Social Media for Business

Social Media Analytics with Facebook -- The Case of Higher Education Institutions BIBAKFull-Text 3-12
  Claudia Brauer; Edward W. N. Bernroider
Social Media Analytics has developed into a new research field within information science in the last years. Due to this fact, currently only a few research results about the usage of Social Media Analytics exist. To fill this gap, we conducted an international delphi study among selected higher education institutions (HEIs) in Germany, Austria and Switzerland which are applying Social Media Analytics related to Facebook. The results demonstrate that the majority of HEIs use more than one Social Media Analytics software tool and consider different Facebook metrics pre-dominantly on a monthly basis to evaluate and to develop their Facebook activities. We conclude that many HEIs lack an integrated Social Media Analytics strategy, under-utilize the real-time capabilities of Social Media Analytics and would benefit from Social Media Analytics.

Engaging Online Review Writing Experience: Effect of Motivational Affordance on Review Quality BIBAKFull-Text 13-21
  Xiaofang Cai; Patrick Y. K. Chau
Online review has become an important repository for consumers to make online buying decisions. However, writing online reviews is a voluntary behavior lacking guidelines and it is hard to guarantee the review quality generated. How to improve online review quality has become a challenge to online retailers and review aggregators. In this study, we explore the design of review writing interface in order to provide engaging writing experience for online reviewers. Using the motivational affordance theory as the theory basis, we define the motivational factors and corresponding design elements, which support reviewers to fulfill their motivation to write their online reviews. We explore how the engaging experience supported by cognitive and social affordances will affect reviewers' writing performance.

Topic-Based Stance Mining for Social Media Texts BIBAFull-Text 22-33
  Wei-Fan Chen; Yann-Hui Lee; Lun-Wei Ku
Recent techniques of opinion mining have succeeded in analyzing sentiment on the social media, but processing the skewed data or data with few labels about political or social issues remains tough. In this paper, we introduce a two-step approach that starts from only five seed words for detecting the stance of Facebook posts toward the anti-reconstruction of the nuclear power plant. First, InterestFinder, which detects interest words, is adopted to filter out irrelevant documents. Second, we employ machine learning methods including SVM and co-training, and also a compositional sentiment scoring tool CopeOpi to determine the stance of each relevant post. Experimental results show that when applying the proposed transition process, CopeOpi outperforms the other machine learning methods. The best precision scores of predicting three stance categories (i.e., supportive, neutral and unsupportive) are 94.62%, 88.86% and 10.47%, respectively, which concludes that the proposed approach can capture the sentiment of documents from lack-of-label, skewed data.
What Do Patients of Different Medical Illness Say About Their Doctors Online? An Analysis of Online Physician Reviews BIBAKFull-Text 34-40
  Ming-Hsin Phoebe Chiu; Chia-Lin Chang
This study aims to understand the role and function of online physician reviews as a process of health information communication, as well as the applications on medical practice and patients and caregivers' medical decision-making process. It collected online physician reviews from two Taiwan-based health information websites -- Good Doctor and Health and DocHos. The analysis framework comprised four aspects: (1) length of reviews; (2) moment in the medical encounter process is reviewed; (3) themes of the reviews; and (4) review intents. In addition to analyzing the structural and textual characteristics of online physician reviews, this study took a step further to identify the relationship between patients of different medical and how they evaluated a medical encounter. In this paper, findings were reported and implications in improving physician-patient communication and patients' empowerment were discussed.

Privacy by Design: Examining Two Key Aspects of Social Applications BIBAKFull-Text 41-52
  Ben C. F. Choi; Joseph Tam
Social applications do not only acquire users' personal information but potentially also collects the personal information of users' social networks. Despite considerable discussion of privacy problems in prior work, questions remain as to how to design privacy-preserving social applications and how to evaluate its effect on privacy. Drawing on the justice framework, we identify two key aspects of social, namely information acquisition and exposure control and examine the effects on user evaluation of social applications. Furthermore, we investigate the impact of this evaluation on usage intention. In doing so, we provide new insight into embedding privacy in technology development.

To Believe or Not to Believe a Call to Action: An Empirical Investigation of Source Credibility BIBAKFull-Text 53-63
  Craig Claybaugh
How well can individuals detect deception from information sources? This study examines consumer evaluations of a real CRM product brochure and a fraudulent one that imitates it. The forged brochure contains malicious manipulations designed to decrease trust in the product and oversell the abilities of the CRM system. This study seeks to see how manipulations of the material are perceived by the individuals and how that impacts their willingness to believe the source credibility of a message.
Keywords: Source credibility; Deception; Trust; Media assurance
Understanding the 'Quality Motion' of Wikipedia Articles Through Semantic Convergence Analysis BIBAKFull-Text 64-75
  Huijing Deng; Bernadetta Tarigan; Mihai Grigore; Juliana Sutanto
To better inform the users of the articles quality, Wikipedia assigns quality labels to the articles. While most of the existing studies of the Wikipedia phenomenon took the quality ratings provided by Wikipedia as the outcome variable of their research, a few yet growing number of studies ask expert raters to rate the quality of selected Wikipedia articles because of their doubts in Wikipedia's ratings. This study aims to check if Wikipedia's ratings really reflect its stated criteria. According to Wikipedia criteria, having abundant and stable content is the key to article's quality promotion; we therefore examine the content change in terms of quantity change and content stability by showing the semantic convergence. We found out that the quantity of content change is significant in the promoted articles, which complies with Wikipedia's stated criteria.

Social Media in Health Care BIBAKFull-Text 76-85
  Brenda Eschenbrenner; Fiona Fui-Hoon Nah
To identify existing streams of research and develop an agenda for future research, we reviewed and synthesized the existing literature relevant to social media in health care. In particular, our review encompassed two themes -- Patient Use of Social Media and Healthcare Organization/Professional Use. Within these overarching themes, we focused on four subthemes (i.e., two under each main theme): community/public health and patient support/use, as well as medical litigation & compliance risk and health education & information sharing. From this review, we have also proposed future research topics and questions to further cultivate this salubrious research domain.

The Value of Expert vs User Generated Information in Online Health Communities BIBAFull-Text 86-95
  Jie Mein Goh; Elena Yndurain
Online health communities are becoming an important source of information whereby users of these platforms, especially patients, participate for knowledge sharing and emotional support. This research examines the perceived value of expert generated information and user (patient) generated information and how it is influenced by different types of information that a user seeks. First, we propose a framework to classify the types of information based on the different types of information patients typically seek out on online health communities using a knowledge based perspective. Then based on this framework, we provide a set of propositions on the perceived value of expert generated versus user driven responses derived by patients. We expect that expert generated responses to have greater perceived value by patients as compared to community driven responses depending on the type of information patients are asking. Specifically, information uncertainty requiring tacit knowledge and high affect such as treatment experiences has greater value when generated by other patients. On the other hand, information uncertainty requiring explicit knowledge and low affect such as understanding the nature of diseases has greater value when generated by expertise. The proposed framework can help to extend the line of research on online health communities and inform health professionals, health organizations or developers of such communities.
A Study of the Uses of Instant Messaging in the Government Offices BIBAKFull-Text 96-105
  Rachael K. F. Ip; Akina K. W. Ho
In recent decades, the pervasiveness of information and communication technologies (ICTs) has changed the communication patterns of the majority of the Internet users. This phenomenon is further intensified by the popularity of instant messaging (IM) chat. IM-chat has not only impacted on personal social communication, but also has significantly changed the way organizations communicate internally and externally. This study aims at examining the impact of three personal level factors on workplace IM uses and the associated communication satisfaction. Our findings reveal that habit and boundary crossover have positive impact on workplace IM uses and communication inhibition has a positive influence on the relationship between workplace IM uses and the associated communication satisfaction. Based on our findings, implications for research and practices are discussed.

Leveraging Social Media for the Fishing Industry: An Exploratory Study BIBAKFull-Text 106-117
  Azrin Shah Ismail; Haliyana Khalid
One of the main challenges in the fishing industry today is the art of connecting buyers and sellers effectively so that information about products, price, quantity and location is synchronized. A lack of communication and technology skills has forced fishermen and fishing industry authorities to depend on intermediaries to market their products, leading to higher prices for consumers. This paper explores the potential use of social media to reduce intermediaries in the fishermen market supply chain. It also aims to understand the critical success factors in using social media as a platform to promote the market.

The Design of IdeaWorks: Applying Social Learning Networks to Support Tertiary Education BIBAKFull-Text 118-129
  Lele Kang; Shaokun Fan; J. Leon Zhao
Online education has progressed from having students passively read and watch materials to having them proactively engage in interactions with other students and teachers. Social network technologies enable students to interact with each other, leading to a new platform for online education. Based on the social learning theory, we design a new social learning network system, named IdeaWorks. Two empirical studies, a usability study and an impact study, were conducted to examine how the social learning network system (i.e., IdeaWorks) has an impact on students' learning activities. The results of the usability study show that IdeaWorks' design performs well on user interface, functionality, and process. Generally, users have a high level of usage intention towards IdeaWorks. The results of the impact study show that learning via IdeaWorks, as well as learning in traditional classrooms, enables users to perceive a high level of social presence, cognitive presence, satisfaction with the course, and satisfaction with the group. However, the impact study also showed that we should enhance IdeaWorks to support instructional communication and group communication in the context of online education.

Contribute Knowledge Continuously or Occasionally? BIBAKFull-Text 130-141
  Yi-Cheng Ku; Chih-Hung Peng; Chih-Ping Wei; Yin-An Chen
This study focuses on continued knowledge contribution. We hypothesize that continued knowledge contribution of members in opinion-sharing communities is influenced by five factors: the number of reviews written, the average of helpfulness scores received from other members, the average of helpfulness scores given to other members, the ratio of the number of negative reviews to the total number of reviews, and the number of trustors. We collect data from Epinions.com and find that these five factors have significant impacts on continued knowledge contribution. These findings have significant theoretical and practical implications for knowledge sharing.

The Effect of Structural Holes on Social Capital and Individual Performance Within Social Media Networks BIBAKFull-Text 153-164
  Yoanna Long; Roberto Mejias
The increasing use of social media has transformed the way that individuals interact with each other and has accelerated the exchange of information and knowledge. Social media has also created the phenomenon of social capital defined as the expected collective or economic benefit derived from the cooperative interaction between individuals and groups. Our research paper explores the effect on structural holes on social capital and participant performance. Structural holes have been defined as weak links to other social media groups outside the primary social network group. Research posits that weak links generate more alternate sources of new information and knowledge than strong links and thus, create more social capital and affect individual performance within a social network. Our results discuss the effect of frequency of user logins, posts counts and hierarchy (as a measure of structural hole) on experience and activeness as a measure of individual performance.

Serving the Social Customer: How to Look Good on the Social Dance Floor BIBAKFull-Text 165-174
  Nicola J. Millard
Customers are increasingly coming to expect brands to deliver customer service on the social media dance floor. The dilemma is that brands don't always understand the mechanics of the dance. The first step to looking good on the social media dance floor is to watch and listen to the dancers -- so this study investigates what customers are actually engaging with on social media (primarily Twitter, Facebook and forums) with respect to brands. It takes two 1 week snapshots of customer (not brand) activity on social media for 13 brands in 6 vertical sectors across 2 time periods (one sample during 2011 and one in 2014). We discovered that customers were actively engaging with brands on a number of levels -- from complaints to complements and beyond -- that different sectors had different challenges, that saying sorry wasn't necessarily enough to satisfy customers and that social dancing often requires brands to do a coordinated conga through multiple channels and complex internal processes.

Are Spectacles the Female Equivalent of Beards for Men? How Wearing Spectacles in a LinkedIn Profile Picture Influences Impressions of Perceived Credibility and Job Interview Likelihood BIBAKFull-Text 175-184
  Sarah F. van der Land; Lotte M. Willemsen; Suzanne A. J. Unkel
This study builds on our previous work on beardedness [1] and explores whether wearing spectacles in a LinkedIn profile picture affects a female candidate's prospects of being invited for a job interview and whether this is contingent on the type of job vacancy. Results of a 2 (spectacle use: spectacles versus no spectacles) × 3 (job type: expertise, trustworthiness, attractiveness) experiment conducted among 139 participants show that bespectacled candidates are perceived as having more expertise and -- to our surprise -- also being more attractive than candidates not wearing spectacles. Moreover, a candidate's perceived credibility is a significant predictor of the intention to invite the candidate for a job interview. Theoretical and practical implications of these findings are discussed.

Mining Social Media for Enhancing Personalized Document Clustering BIBAKFull-Text 185-196
  Chin-Sheng Yang; Pei-Chun Chang
Social media is nowadays an excellent platform for gathering user intelligence for supporting business intelligence applications. Social tagging system (aka. folksonomy) is a critical mechanism for collaboratively creating, organizing and managing the wisdom of crowds. The knowledge gained from social tagging system should be tremendous assets for conducting and improving various business intelligent applications. Consequently, the purpose of this study is to examine the values of folksonomy on an important business intelligent task, namely personalized document management. Specifically, we employ Delicious, a pioneered social bookmarking service, to construct a statistical-based thesaurus which is then applied to support personalized document clustering. According to our empirical evaluation results, social tagging system indeed improve the quality of the statistical-based thesaurus in comparison with that constructed on the basis of a general-purpose search engine in generating personalized document clusters.

The Influence of Individual Affective Factors on the Continuous Use of Mobile Apps BIBAKFull-Text 197-206
  Yi-Hsuan Yeh; Belinda Chen; Nien-Chu Wu
Mobile apps have attracted a substantial amount of attention in mobile commerce. Usage behavior of consumers is always an important issue in this research area. The objective of this study is to explore what factors will affect an individual's continuance intention to use mobile apps. We proposes a research model that integrates the Task-Technology Fit (TTF) and Theory of Reasoned Action (TRA), which are augmented with concepts of affective factors. We conduct an online survey and the results show that a higher degree of TTF and VTF (Value-Technology Fit) resulted in a more positive attitude towards using the mobile app. SN and attitude had strong significant impacts on users' continuance intention to use the app. However, TTF and VTF had no significant effect on the continuance intention to use the app.

Identifying Appraisal Expressions of Online Reviews in Chinese BIBAKFull-Text 207-218
  Pei Yin; Hongwei Wang; Wei Wang
With the development of Web2.0 technology, an increasing number of consumers are giving comments on products over the Internet, thus opinion mining rises in response to the requirement of retrieving valuable information in speed. After thoroughly analyzing the style of language and the ways of expression in Chinese, this paper proposes a semantic lexicon-based method to identify the appraisal expressions in Chinese online reviews. A comparative experiment based on cellphone online reviews in Chinese is conducted in this research, and the result indicates that the proposed method is quite promising and outperforms the two baselines (a statistic orientation method and a semantic orientation method). Moreover, the method is applied to a comparative evaluation of two popular cellphones, demonstrating the theoretical significance and the practical value of this research.

The Knowledge Gap: Providing Situation-Aware Information Assistance on the Shop Floor BIBAFull-Text 232-243
  Mario Aehnelt; Bodo Urban
Situation-aware information assistance strongly depends on the quality of available contextual background knowledge for an application domain and on its automatic processing. In this paper we present a conceptual approach towards using cognitive architectures to provide information assistance and allow complex decision making based on expert knowledge. We transfer our approach into a technical concept which was finally implemented as part of the Plant@Hand assembly assistance system within a mobile workshop trolley. The paper gives insights into our work on formalizing knowledge and providing ad-hoc mechanisms for planning, assisting and controlling assembly tasks on the manufacturing shop floor.
An Interactive Assessment Instrument to Improve the Process for Mobile Service Application Innovation BIBAKFull-Text 244-255
  Karen Carey; Markus Helfert
In recent years, the adoption and use of new mobile service applications have not proliferated, consequently many applications fail to generate a profit [1, 2]. One reason for this is poor decision making in the process of mobile service innovation [1, 3, 4]. This paper details the construction of an interactive assessment instrument to improve decision making in this innovation process. To design the interactive assessment instrument, we follow a Design Science Research Methodology (DSRM) -- a methodology which is new to HCI [5]. Adhering to the DSRM, the paper details the iterative design and evaluation cycles required to build and evaluate the instrument. The paper concludes that the designed assessment instrument improves the innovation process, by providing transparency, while also facilitating communication and understanding amongst team members. Additionally, the paper demonstrates that the DSRM can be of great use to design and evaluate interactive IT artifacts within the HCI field.

The Influence of Location and Social Network on Customers' Acceptance of Mobile Marketing: Evidence from Group Buying Field Experiment BIBAKFull-Text 256-266
  Xi Chen; Ruibin Geng; Chee Wei Phang
With the rapid development and widespread popularity of smart phone devices, location-based social networking service (LBSNS) creates an era of GeoLife2.0 where people can share life experiences and connect to each other with their location histories. Previous academic studies have also realized the crucial role of location and social network on mobile marketing. However, many of them have been conceptual work using structural equation modeling, and the effects of these two factors are never considered at the same time. In our study, mobile marketing is exemplified as a time-limited, group-based "two for the price of one when you get a friend to buy together" promotion campaign advertised via mobile devices. Field experiment was conducted to explore the influence of location and social network on consumers' decision to accept mobile promotions. We then conducted follow-up surveys that revealed users' personality features and psychological states as supporting materials to explain our field experiment observations.

Dishonest Behavior at Self-Service Checkouts BIBAKFull-Text 267-278
  Susan Creighton; Graham Johnson; Paul Robertson; Jan Law; Andrea Szymkowiak
Self-service technology could be argued as creating less personal transactions when compared to traditional checkouts involving a sales assistant for the entire transaction process, which may affect customer behavior. The aim of our study was to investigate the perceived influence of social presence at self-service checkouts by staff and its perceived effect on dishonest customer behavior. Twenty-six self-service checkout staff took part in a series of semi-structured interviews to describe customer behaviors with self-service. With respect to actual physical social presence, staff reported that more customer thefts occurred when the self-service checkouts were busy and their social presence was reduced. Staff also reported that perceived and actual social presence is likely to reduce thefts. Future research will elaborate to which extent the perceived social presence via technological systems might support staff in their task to assist customers and reduce dishonest behavior.
Keywords: Self-service; Social presence; Dishonest behavior
Consumer Adoption of Social Commerce BIBAKFull-Text 279-287
  Nick Hajli; Xiaolin Lin
The paper considers the emergent, so called, 'social commerce' imperative which enables consumers to generate active WEB content and engage commercially with providers through social networking systems. It is apparent that little research currently addresses the need for an understanding of consumer adoption in this respect and therefore further critical issues involved in contemporary consumer research. Our contribution relates to a consideration of adoption behaviour through the formulation of the technology acceptance model (TAM), social commerce constructs and trust. We consequently present specific insights into consumers 'intention to buy' through social commerce engagement. The results of our research also inform providers with an initial important awareness of the impact of social media within a commercial context.

Helping Customers Help Themselves -- Optimising Customer Experience by Improving Search Task Flows BIBAKFull-Text 288-299
  Sue Hessey
Large consumer-facing enterprises can offer a wide range of products and services to their customers. In parallel, often the quantity of information offered online to customers to support these services is similarly large in scale -- so how can an enterprise optimize online support to improve customer satisfaction and lower support costs to the business? To address this problem we have used quantitative and qualitative methods to identify the most significant topics concerning customers over a 14-week period. These analyses in turn informed our user test design, which investigated individual search-for-help behaviors. The output from these analyses was used to form recommendations for high-priority, low cost interventions in the User Interface design of the support website, so that customers are more willing and able to help themselves.

Digital Rights Strategies in a Virtual World Marketplace BIBAKFull-Text 300-311
  Yuanrong Hu; Si Fan; Qiuhong Wang
This paper adopts the Heckman two-step model to analyze the impact of copyright strategy on sales performance of digital product, using the panel data comes from online virtual goods transaction website Xstreet.com. The results show that (1) significant relationship exists between sales performance and copyright strategy of digital product, but the influence of each copyright strategy on sales performance are different; (2) A seller's copyright structure within same product line can also affect sales performance of a digital product, thus in order to optimize the copyright combinations, a seller should fully consider the copyright strategy within the whole product line.

Research on Virtual Item Purchase Intention in Taking Part in Mobile Device Games: Taking the Middle and Old Aged Players for Example BIBAKFull-Text 324-334
  Chia-Yu Kao; Chenwei Chiang
This study targets middle and old aged players' mobile game participations, as well as their purchase intention of virtual items, and an internet-based survey is conducted. Results show that when players are in the flow channel, motivations such as competition and self-assurance, game playability, artistry, and sociability, increase players' purchase intention for virtual items. On the other hand, entertainment of motivation and mobility of playability, decrease players' willingness to purchase virtual items. Younger players demonstrate significant difference than middle and old aged players on mobile games. However, gaming market of middle and old aged players shouldn't be overlooked. More in depth investigation of middle and old aged players' needs for mobile games is helpful for designing better games and campaigns attracting middle and old aged players, and increase their purchase intention for virtual items.

Key Factors in Developing Omnichannel Customer Experience with Finnish Retailers BIBAKFull-Text 335-346
  Satu Peltola; Harri Vainio; Marko Nieminen
Change in consumer behavior towards increased use of digital services throughout the buying process drives retailers to rethink their services. Contemporary shoppers engage in a mixture of real-life and digital activities combining events in brick-and-mortar stores with online and mobile browsing. Our interviews with seven Finnish retailers show that the changing consumer behavior affects not only services but also other operations including organizational structure and supply chains. For analysis purposes, we modified customer journey maps to record and illustrate user activity. We conclude that a good omnichannel customer experience lies in the unity of retailer's organizational culture, pricing, operations, and communications. Instead of full-range digital and physical service offering, seamless and intuitive linking of consumer touch-points appears as a promising path. Our results contribute to better understanding of omnichannel customer experience indicating the need for a more profound approach in omnichannel development to more traditional channel and customer interface development.

The Role of Brand Loyalty and Social Media in E-Commerce Interfaces: Survey Results and Implications for User Interfaces BIBAKFull-Text 347-357
  Dimitrios Rigas; Hammad Akhtar Hussain
This paper explores the role of brand loyalty and social media in e-commerce interfaces. A survey consisting of 118 respondents was contacted to address the questions relating to online shopping and brand loyalty. The issues investigated included the link between the frequency of access and time spent on an e-commerce user interface, and brand loyalty, gender and age profile differences, and the role of social media to branding and on-line shopping. It was found that online loyalty differs from offline loyalty and loyalty also differed across genders, showing that males may develop loyalty easier than females when shopping online. Information shared about products on social media by friends and family played an important role in purchase decision making. Website interface and ease of navigation were also key aspects for online shopping. The research concluded with some pointers towards multimodal interfaces that aid loyalty with the use of interactive multimodal social media.

The Mediating Role of Perceived Security: An Empirical Study of Mobile Wallet Adoption in USA BIBAKFull-Text 358-369
  Norman Shaw
Because the USA is introducing 'chip and pin' card standards in 2015, payment terminals are being implemented that have the capability of reading plastic cards that are simply waved in proximity to the terminal. With the aid of a 'mobile wallet' app, smartphones are able to substitute for the physical card and complete contactless payments. The transaction flows through an ecosystem that is comprised of the smartphone manufacturers, software developers, mobile network providers and financial institutions. However, consumer adoption has been slow and, in order to help practitioners with their investment decisions, this study seeks to explain the factors that influence intention to use. Theory extends the technology acceptance model with the constructs of perceived security and personal innovativeness. An empirical study supports the hypotheses and explains the mediating role of perceived security.

Productpedia -- A Collaborative Electronic Product Catalog for Ecommerce 3.0 BIBAKFull-Text 370-381
  Wee-Kek Tan; Hock-Hai Teo
Despite the advancements made in ecommerce technologies over the past years, the inability to define and exchange semantically rich and accurate product information among ecommerce websites/applications has continued to intrigue researchers. This problem has taken on greater urgency because it impedes the realization of the full benefits of Ecommerce 3.0. The present research conceptualizes, designs and implements a cloud computing-based platform that enables global merchants to maintain a collaborative Electronic Product Catalog (EPC) known as Productpedia. This collaborative EPC platform addresses numerous shortcomings of prior researches by (1) maintaining a single centralized EPC database; (2) negating the need to synchronize and convert data; (3) creating an integrated meta-model ontology for merchants to define previously unclassified product information without the involvement of domain experts; and (4) enabling an Open Application Programming Interface based on RESTful web services to facilitate direct modification of the EPC database by even third-party applications.

The Moderating Role of Perceived Effectiveness of Provider Recommendations on Consumers' Satisfaction, Trust, and Online Repurchase Intention BIBAKFull-Text 382-391
  Hongpeng Wang; Rong Du; Shizhong Ai; Zhe Chi
Despite the importance of online provider recommendations in e-commerce transactions, there is still little understanding about how provider recommendations impacts on customer retention. Addressing this gap, this study introduces a key construct, perceived effectiveness of provider recommendations (PEPRs) to investigate the differential moderating effects of PEPRs on the relationships between satisfaction, trust and repeat purchase intention. The research models are designed based on a research model and an online survey is conducted with 130 respondents. We draw conclusions that (1) PEPRs negatively moderate the relationship between satisfaction with vendor and trust in vendor and (2) PEPRs positively moderate the relationship between trust in vendor and repurchase intention. These findings are important theoretical contributions to know that first-hand experience can be to some extent replaced by supplementary information. In addition, we give some managerial countermeasures towards the new situation.

An Exploratory Study of Website Localization Strategies: The Effect of Exogenous Factors BIBAKFull-Text 392-402
  Tailai Wu; Chih-Hung Peng; Yani Shi; Choon Ling Sia
This paper explores the relationship between website localization and their exogenous factors. Three exogenous factors are studied: online transaction availability, product types and history length. Based on the previous studies, this paper distinguishes website localization design strategies from website localization degree. Through a content analysis of Fortune 1000 companies' websites, this paper finds that website localization strategies are positively related to website localization degree and that product types positively associate with website localization degree. Besides, all the exogenous factors are relevant to some specfic website localization strategies.

Consumers' Purchase Intention of Online Product Customization Using Different Terminals with/without Default Template BIBAKFull-Text 403-413
  Jiaheng Xie; Wangsheng Zhu; Kanliang Wang
To provide more personalized products, many vendors allow consumers to design their products by selecting attribute by attribute, a technology commonly called customization. Complexity of customizing process has been a concern for consumers, and default template was introduced to solve this dilemma. With the rapid development of mobile internet, mobile terminals, such as tablets and smart phones, play ever vital roles in conducting e-commerce. The shift from desktop computers to mobile terminals may generate changes in the response of consumers viewing identical content as digital interfaces fundamentally change the experience of the content they access. However, little attention has been paid to the impacts of different terminals on consumers' purchase intention. This research aims to find out the impact of default template on consumers' purchase intention, and the interaction effect that terminal and need for uniqueness have on the relationship. A lab experiment was conducted to test the proposed hypothesis. The result shows that default template increase consumers' intention to buy. Besides, terminal and need for uniqueness have moderating effect on the relationship.

An Empirical Study of User Decision Making Behavior in E-Commerce BIBAKFull-Text 414-426
  Dongning Yan; Li Chen
The large number of customer reviews and inconsistent writing style make it difficult for users to digest information and make online purchasing decisions. In light of human decision making theory, an in-depth understanding of user decision making behaviors serves as the foundation of effective information displays. In this paper, we conduct a formative study to empirically investigate user decision making behaviors in online hotel booking, in particular, with respect to customer reviews. Through analysis of the results, we identify the information decision makers are inclined to seek and the decision strategies they utilize to process information in three stages of online purchasing.

Exergames for Older Adults: Towards Sustainable and Transferrable Health Benefits BIBAKFull-Text 429-436
  Young Anna Argyris; Taiwoo Park
This study presents an exergame called Pressure-Ball game that is designed to increase health among institutionalized older adults. As many older adults develop sedentary lifestyle in which their physical activities are reduced, it is important to engage them in a mild exercise activity. The mild exercise activity can increase their confidence in fitness levels and reduce fear of injuries; thereby building active lifestyle that can be sustainable and transferrable to other domains of life. To assess health benefits brought about by Pressure-Ball game, we propose a longitudinal study that employs a series of experiments in retirement homes in Midwest. The completed research has potential to provide health benefits to aging population.

Reimagining Project Management Applications via Gamification BIBAFull-Text 437-445
  Charles Butler
The objective of this paper is to present a prototype design of a project management application which has been designed to leverage the power of gamification. The specific set of gamified features contained within the prototype follow the model set forth in previous work which attempted to aid gamification designers in the selection and implementation of the most effective mechanics for whatever the intended purpose. This was done by mapping a number of gamification mechanics to existing effects in behavioral economics, which allows designers an unconventional insight into the behavioral reasons as to why various methods of gamification affect a user-base. It should also be noted that unlike some gamification implementations which can, at times, be seen in a negative light by being excessively game-like, the focus here is on bringing gamification into the business setting in a serious and professional manner in order to ease adoption among all users.
A Study on Mobile Fitness Application Usage BIBAKFull-Text 446-457
  Ben C. F. Choi; Nathaniel T. Lee
Although the importance of physical activity in a healthy lifestyle is well known, little attention has been paid thus far to systematically understand users' continued usage of mobile fitness applications. The objective of this paper is to understand the determinants of usage of mobile fitness applications beyond initial adoption. The research model is tested with data collected from fifty users of mobile fitness applications. The results indicate that expectation confirmation is the key predicator of attitudes towards the application, such as perceived usefulness, perceived enjoyment, and satisfaction. Furthermore, users' attitudes are found to determine continued usage intention. Overall, this paper contributes by integrating intrinsic motivation into the expectation-confirmation model for mobile fitness application usage.

Developing a Context Model of Process Variants for Business Process Integration BIBAKFull-Text 458-468
  Jorge E. Giraldo; Demetrio A. Ovalle; Flavia M. Santoro
Since the integration of business process variants can be affected by contextual information the aim of this paper is to propose the development of a context model for Business Process Integration that considers the propagation of process changes towards process variants of the reference model. The method used to develop such a model focuses on following stages: (1) conceptualization of process variants, by building a related ontology, (2) identification of contextual elements, (3) definition of operational and organizational constraints; (4) formalization of contextual situations in the variants, and (5) construction of a reasoning mechanism for searching and retrieval of process variants. In order to validate the context model proposed we implemented both a prototype and a case study that consider each of the five stages proposed. The obtained results demonstrate the effectiveness of using this kind of approaches for business process integration.

Designing Enterprise System Information Architecture Using Task Data BIBAKFull-Text 469-480
  Dawei Huang
Much of today's information architecture for enterprise tools is organized in a complex and feature oriented way -- frustrating the users and requiring tons of learning to be efficient. We introduced a task taxonomy research project that studied a few hundred database users to understand their responsibilities, roles, and tasks. We created a task taxonomy model filled with large quantitative data on tasks. We found task hierarchy emerged from the model and it had a strong relationship with user roles -- implying role-based workspace design principles. With the task hierarchy data, the degree of relevance of task hierarchy could be estimated and applied for enterprise information architecture designs.

Kindle: How Gamification Can Motivate Jobseekers BIBAKFull-Text 481-492
  Bart van der Kruys; Vassilis Javed Khan
Prolonged unemployment can lead to depression and a loss of self-esteem. Gamification is a strategy that engages and motivates groups of people by implementing game mechanics and dynamics in an existing non-gaming system. This paper studies the possibility of using gamification to motivate job seekers. To test the effectiveness of the ideas proposed in this paper, a between-subjects study was executed. Those results, although preliminary, do suggest the potential of including gamification features in job seeking systems.

Enhancing User Experience of Enterprise Systems for Improved Employee Productivity: A First Stage of Case Study BIBAKFull-Text 493-500
  Honglei Li
User experience has been regarded as the focus of technology design following the diffusion of information technology into the society level. There are many researches discussing user experience as a concept from the software testing and design perspective and seldom the specific dimensions of user experience are investigated. This research attempted to conduct a case study to explore the psychological dimensions of user experience from the interpersonal relationship theoretical perspective. Specifically, a case study on the usage of SAP ERP system has been conducted and 8 enterprise systems users have been interviewed to reflect on their interactions with the ERP system. The interpersonal relationship features is reported missing from the current enterprise systems design. Implications to both researchers and practitioners are provided.

Designing Mobile Applications for Organizational Routines BIBAKFull-Text 501-512
  Kenny Lienhard; Thomas Boillat; Christine Legner
As tablet computers and smartphones have become widespread, organizations are increasingly using mobile applications for supporting routines, i.e., repetitive patterns of activity that occur throughout an organization. However, prior studies see user interactions mostly as a silo -- able to help individual users perform better -- but not embedded in an organizational context of a user group or company. In order to address this gap, the paper at hand looks into the roles of mobile applications in supporting routines, and the related principles for mobile application design. We present two mobile applications that support domain experts in two diverse contexts, automotive car dealerships and hospitals. Based on their analysis, we were able to identify patterns as well as a number of design principles for mobile applications supporting organizational routines.

Effects of the Use of Points, Leaderboards and Badges on In-Game Purchases of Virtual Goods BIBAKFull-Text 525-531
  Fiona Fui-Hoon Nah; Lakshmi Sushma Daggubati; Amith Tarigonda; Raghu Vinay Nuvvula; Ofir Turel
Game design elements are major factors in gamification. In this study, we seek to examine the impact of game design elements on users' in-game purchases of virtual goods. The purchase of virtual goods due to players' intrinsic motivation has been studied but little is known about the purchase of virtual goods due to the use of game design elements (i.e., Points, Leaderboards and Badges) built into the games. Extending our knowledge to this realm can help researchers to better understand gamers' behaviors, and game designers and marketers to better promote and sell virtual goods in online games.

Teleworkers and Their Use of an Enterprise Social Networking Platform BIBAKFull-Text 532-541
  Daniel Weiss; Laurie E. Damianos; Stan Drozdetski
This study surveyed teleworker usage of a social networking platform within an enterprise. Compared to on-campus employees, teleworkers exhibited earlier adoption, higher percentage of contributions, more variance in work hours, and lower membership in socially-oriented groups (versus work focused groups). The last result seems counterintuitive, and we propose two possible reasons for this phenomenon: the perceived need to cultivate an external perception of productivity, and lack of access to social events tied to specific geographic office locations. In addition, we provide insights, gleaned from interviews, into teleworker use of collaboration tools.

Element Prioritization for Online Service Identity Management BIBAKFull-Text 542-549
  Hoon Sik Yoo; Young Hwan Pan; Ping Shui; Da Young Ju
Services have taken the center stage over products in the industrial world. Thus, there have been many studies that focused on how to define and utilize service identity. The purpose of this study is to discover the elements of service identity that need to be managed with top priority when corporations manage their respective service identity. To discover the elements thereof and assess priorities, this study structured service identity based on the conventional theories. This study defined the specific elements of service identity through expert FGI. Also, this study deducted the priorities as the 14 experts of UI/UX/service design conducted AHP evaluation as to the elements thereof. As a result, this study found that those visual elements such as color, icon and layout had the highest priority. This study also found that the importance of the functional elements was relatively lower, whereas the operational elements had the lowest priority.

Gamification and Persuasion of HP IT Service Management to Improve Performance and Engagement BIBAKFull-Text 550-562
  Yue Yuan; Ke Ke Qi; Aaron Marcus
Currently, IT service management groups in many different companies are facing a common challenge: how to motivate IT service desks to perform more effectively and productively in order to reach desired customer service objectives/goals and promote customer satisfactions. Undoubtedly, IT service desks' performance and engagement will directly influence the delivered service, and the quality of the service will either enhance or degrade customer loyalty to a company's brand and business. Accordingly, we present an effective and feasible way to incorporate gamification and persuasion as the incentive mechanism into the current product, to socially reward IT service desks for their performances, and thereby to increase their motivation to contribute and to improve their performance.

Low Ambiguity First Algorithm: A New Approach to Knowledge-Based Word Sense Disambiguation BIBAKFull-Text 565-574
  Dongjin Choi; Myunggwon Hwang; Byeongkyu Ko; Sicheon You; Pankoo Kim
The Word Sense Disambiguation (WSD) problem has been considered as one of the most important challenging task in Natural Language Processing (NLP) research area. Even though, many of scientists applied the robust machine learning, statistical techniques, and structural pattern matching approach, the performance of WSD is still not able to bit human results due to the complexity of human language. In order to overcome this limitation, currently, the knowledge base such as WordNet has gained high popularity among researchers due to the fact that this knowledge base can extensively provide not only the definitions of nouns and verbs, but also the semantic networks between senses which were defined by linguists. However, knowledge bases are not fully dealing with entire words of human languages because maintaining and expanding the knowledge base is huge task which requires many efforts and time. Expanding knowledge base is not a big issue to concern however, a new approach is the major goal of this paper to solve WSD problem only based on limited knowledge resources. In this paper, we propose a method, named low ambiguity first (LAF) algorithm, which disambiguates a polysemous word with a low ambiguity degree first with given disambiguated words, based on the structural semantic interconnections (SSI) approach. The LAF algorithm is based on the two hypotheses that first, adjacent words are semantically relevant than other words far way. Second, word ambiguity can be measured by frequency differences between synsets of the given word in WordNet. We have proved these hypotheses in the experiment results, the LAF algorithm can improve the performance of traditional WSD results.

A Data Visualization System for Considering Relationships Among Scientific Data BIBAKFull-Text 575-584
  Jangwon Gim; Yunji Jang; Yeonghun Chae; Hanmin Jung; Do-Heon Jeong
With the recent explosive increase in the amount of web-based scientific data in big data environments, various researcher support systems have been developed to help discover desired scientific data and search insights. Scientific and researcher-related data are also applied to social networking services, thus promoting inter-researcher networking. However, much time and effort is put into big data mining to extract information customized to researchers' specific needs. Moreover, systems that facilitate information extraction by schematizing various inter-data relationships are absent. In this paper, we propose a system that facilitates relevant information extraction from scientific data and provides intuitive data visualization. Such data visualization allows efficient relationship expression between scientific data (relationships between researchers, acronyms and technical terms, and synonyms of a technology name), and provides an author disambiguation interface for authors with the same name. As a result, researchers can extract relevant information from big data with scientific data, and obtain significant information based on cleansed and disambiguated data.

Design of Marketing Scenario Planning Based on Business Big Data Analysis BIBAKFull-Text 585-592
  Seungkyun Hong; Sungho Shin; Young-min Kim; Choong-Nyoung Seon; Jung ho Um; Sa-kwang Song
As the amount and the type of data for business decision making are rapidly increasing, the importance of big data analytics is gradually critical for making effective business strategy. However, big data analytics based decision making systems basically requires distributed parallel computing capability in order to make timely business strategy recommendation via processing huge amount unstructured as well as structured business data. We introduce a big data analytics system for automatic marketing scenario planning based on big data platform software such as Hadoop and HBase. The analytics methodology for scenario planning is based on prescriptive analytics which is the most advance methodology consisting of generation of business scenarios and their optimization, among the three analytics of descriptive, predictive, and prescriptive analytics. Additionally, we developed a prototype of marketing scenario planning system and its graphical user interface, as well as the system architecture based on Hadoop eco-system based distributed parallel computing platform.

Applying the Rules of Image Construction to Graphical Representation of Infection Prevention Contextual Data in a Communicable Format BIBAKFull-Text 593-604
  Valeriya Kettelhut; Trevor Van Schooneveld; James McClay; Ann Fruhling
Antibiotic resistant infections are a serious threat for public health. Hospitals are accountable for preventing the infection transmission among patients. Situation awareness interface may improve healthcare workers' awareness about daily aberrations in infection burden and risks associated with infection transmission and underuse of preventive interventions. This study attempted to apply the rules for image contraction to furnish large amount of the electronic health record epidemiological data into a single image that would reduce informational overload and increase infection prevention situational awareness in a distributed group of healthcare workers. This research postulated that contextualization of the infection prevention data may provide critical cues for decision-making and detecting situations when prevalence and variety of antibiotic-resistant carriers reach dangerous thresholds.

Design on the BPEL Engine Generator for Adding New Functions BIBAKFull-Text 605-612
  Donggyu Kwak; Jongsun Choi; Jaeyoung Choi; Hoon Ko
Business Process Execution Language (BPEL) is widely using in various domains because it describes the flow of works depending on their conditions, rules and the call of Web services in service-oriented computing environment, and many experts have been studying the BPEL to use, but still the high cost is required in existing systems. Also, the systems can only add a single function, and it is difficult to design and add new functions as necessary. To overcome this problem, it suggests the new function (?) to be low cost BPEL engine generator by defining XAS4B document that can extend the grammar function of BPEL through XML schema in order to add new functions as necessary and by processing the document. However, new functions, which cannot be found in BPEL grammar, are required in a specific domain. When a new function, which does not exist in the existing language, is required, the domain-specific language should be newly defined and developed in general. One more advantage of the proposed system is able to add new functions without modifying BPEL engine by AspectJ.

A Dynamic Weighted Majority Algorithm for Dynamic Data Relationships Concept Drift Detection BIBAKFull-Text 613-622
  Szu-Yin Lin; Chun-Hsian Lin
In a dynamic environment, the data are changed almost instantly. It is difficult and time-consuming to find the correlation between data. At the same time, the concept drift might happen along with data change in the dynamic environment. In order to stimulate the highly correlated data to support better prediction and detected the concept drift, this study proposes a distributed dynamic data driven Application system (DDDAS)-based dynamic weighted majority (DWM) algorithm to solve the issue. The proposed algorithm tries to find the correlations between data by DWM. Moreover, it is capable of detecting concept drift. The simulation result shows the DDDAS-based DWM algorithm has up to 89% accuracy in simulation case, and able to find the concept drift.

Enhancing the Explanatory Power of Intelligent User Interfaces with Diagrams BIBAKFull-Text 623-632
  Robbie T. Nakatsu
I describe techniques that can be used to enhance the explanatory power of intelligent user interfaces. I focus on advice-giving systems that provide recommendations to end-users on how to solve problems, or help end-users make the right decisions. By explanatory power I am referring to the ability of a system to "explain" its own actions. One approach to endowing a system with explanatory power is to develop some kind of diagram -- a graphical model that shows how something works or makes something easier to understand. I explore, in particular, "dynamic" diagrams in which the end user can explore the diagrammatic structures in a variety of ways to aid in understanding and problem-solving.

A Comparison of Hybrid Neural Network Based Breast Cancer Diagnosis Systems BIBAKFull-Text 633-639
  Hsine-Jen Tsai; Hao-Chun Lu; Tung-Huan Wu; Chiang-Sheng Lee
Breast cancer is the second leading cause of death among the women aged between 40 and 59 in the world. The diagnosis of such disease has been a challenging research problem. With the advancement of artificial intelligence in medical science, numerous AI based breast cancer diagnosis system have been proposed. Many researches combine different algorithms to develop hybrid systems to improve the diagnosis accuracy. In this study, we propose three artificial neural network based hybrid diagnosis systems respectively combining association rule, correlation and genetic algorithm. The effectiveness of these systems is examined on Wisconsin Breast Cancer Dataset. We then compare the accuracy of these three hybrid diagnosis systems. The results indicated that the neural network combining with association rule not only has excellent dimensionality reduction ability but also has the similar accurate prediction with correlation based neural network which has best accurate prediction rate among all three systems compared.

Rule-based Medical Decision Support Portal for the Emergency Department BIBAKFull-Text 640-652
  I-Chin Wu; Tzu-Li Chen; Yen-Yi Feng; Ya-Ling Cheng; Yung-Chih Chuang
Hospital Emergency Department (ED) crowding has led to an increase in patients' waiting times; thus, solving this problem requires a better understanding of a hospital's patient flow and the behaviors of patients. Existing research on ED crowding is sparse and has tended to focus on the present crowding state. Recent studies have addressed the importance of analyzing the length of stay (LOS) to understand the behaviors of patients in the ED. In this research, we proposed a rule-based data-mining approach to investigate the relationship between various types of patient behaviors and their LOS, and to build a model to predict patient LOS. The objective of this study is to build an interactive decision support system (DSS) for Mackay Memorial Hospital, which has the second-largest ED in Taiwan and is a representative institute. Accordingly, the aim of this study is twofold (1) building the DSS based on the proposed medical data-mining process in the ED and (2) visualizing the extracting rules and the statistical data in the proposed rule-based medical decision support (R-MDS) visualization portal. We introduce the system framework with associated modules in this study. We aim to integrate domain knowledge of the hospital ED with the data-mining technique to develop the system and provide interactive DSS using modern visualization techniques. We also believed that the qualified rules can be validated effectively and efficiently by experts with the aid of the proposed system.

Why Innovations of Capital Market IT Systems Fail to Diffuse into the General Public? BIBAKFull-Text 655-666
  Sapumal Ahangama; Danny Chiang Choon Poo
Capital markets represent an important component of the economy of any country. Yet, it has been found that in a majority of countries, participation of the general public in capital markets is at a low level even with the availability of online trading platforms. In this study, we integrate constructs of diffusion of innovation, technology acceptance and trust models to form a context specific model in order to identify the factors influencing the general public in using online trading systems. Implications of a survey study carried out among a diverse group of investors are presented in this paper.

A Critical Examination of the Causes of Failed IS Implementation: A Review of the Literature on Power and Culture BIBAKFull-Text 667-678
  Hassan Aldarbesti; Lazaros Goutas; Juliana Sutanto
As organizational life is becoming increasingly dependent on information systems (IS), proper IS implementation has become imperative. If it is not properly implemented, it may disrupt the organizations' daily operations and strategic decision-making, which can carry significant monetary consequences. Sometimes IS implementation is halted halfway, or at any stage of the implementation process, which may also carry significant monetary consequences to the organizations, especially when the size of the IS implementation projects is large. This paper focuses on the latter. Through our literature review, we discovered that it is the human aspect, instead of the technology aspect, that contributes to most of the failed IS implementations. To better understand how this could take place, our study highlights two possible reasons of failed IS implementation: (1) organizational culture complexity and (2) power and politics in the organization.

The Smart Steering Wheel Cover Design: A Case Study of Industrial-Academic Collaboration in Human-Computer Interaction BIBAKFull-Text 688-698
  Eleonora Ibragimova; Arnold Vermeeren; Peter Vink; Nick Mueller; Leanda Verboom
The transition to a knowledge-based economy has placed expertise and innovation rather than physical resources as the assets driving economic growth and international competitiveness [1]. The result is a relentless pursuit by businesses to innovate as a means to gain competitive advantage in their industry. However, with shorter product lifecycles, increasing product complexity and rising research and development costs, even large firms are struggling to develop new products on their own. Whereas there is a strong demand from businesses to obtain external research and development resources [2], academic institutions represent a large body of knowledge that often sees no practical implementations. This paper discusses the integration practices in new product development on the case study of The Smart Steering Wheel Cover design. A research team from Delft University of Technology collaborated with a mobile solution firm, MOBGEN, to design a system to enhance the safety and fuel-efficiency of drivers. Analyzing the risks and benefits, challenges and opportunities in industrial-academic collaborative projects, recommendations are presented on optimal collaborative practices in the field of human computer interaction.

  Yumei Luo; Cheng Zhang; Yunjie Xu
Investments on information stems (IS) are costly. After the initial adoption of Information Systems, the value of IS to an organization depends on employees' innovative use of various features of IS in the infusion stage. Innovative use of IS, a key activity of technology infusion, depends not only on individual effort, but also on group effort of teams. Grounded on the research of individual-collective process, this paper seeks to build a situational contingency model of how individual innovative use of IS affects group innovative use.

Vision 2020: The Future of Software Quality Management and Impacts on Global User Acceptance BIBAKFull-Text 748-760
  Robin Poston; Ashley Calvert
This paper explores the future evolution of software quality management (SQM), testing, and global user acceptance approaches keeping in mind the evolution in software and technology quality management in general, including new technologies and the increasing adoption of new software development life cycle methodologies such as Agile and Scaled Agile. These evolutions are forcing quality organizations to change the way they approach software quality processes, including increased outsourcing of development, and the need to update traditional testing and user acceptance testing approaches which lag behind with manual and invasive techniques. User acceptance as we know it today must evolve.
   This discussion about evolution should deemphasize the role of the end user in "testing" and emphasize the end user's role in acceptance, adoption, and ability to influence the quality and usability of software much further upstream in the development life cycle. User acceptance teams should increase their role in user experience, the development of usability standards, non-invasive automation techniques gathering usage data, etc. All of these mechanisms should increase the ability of the end user to influence product quality and enhance the user experience and acceptance. Perceptions of end user's participation in user acceptance events need to be transformed away from just another cycle of software testing. User acceptance should not be about testing, but about validating that the end user needs and expectations have been met. All testing and other quality processes should be completed and defects corrected before the end user is engaged in the process of "accepting" the deliverable.
   Thus, this effort will explore the future of SQM and its impacts on global user acceptance. We will discuss how organizations involve users throughout the development life cycle to facilitate adoption, user experience, and usability of new technologies. This discussion will be embedded in the use of futuristic new technologies and development methodologies. To explore these notions, this study gathers input from technology visionaries about best practices approaches for facilitating SQM and user acceptance throughout the development life cycle.

Early-Stage Software Start-up Survival: the Effects of Managerial Actions on Firm Performance BIBAKFull-Text 761-771
  Yunfei Shi; Dongming Xu; Iris Vessey
The emergence of software start-ups contributes to society by driving innovation as well as by creating jobs. Research, to date, mainly concentrates on either start-ups in general or established software firms. Little research has been conducted directly into software start-ups. The objective of this research is to understand how early-stage software start-ups survive. We develop a conceptual model for explaining early-stage software start-up survival. The conceptual model illustrates important resources, capabilities, and managerial actions that facilitate high levels of software start-up performance. Our research contributes theoretically to IS literature in general by developing a theory of how software start-ups survive in the early stages and to resource-based research specifically by explaining the actions management takes in deploying resources and capabilities to achieve high levels of performance.

In this paper, we propose an architecture-oriented design method for human-computer interaction systems. This design method adopts the structure-behavior coalescence (SBC) architecture as a systems model. SBC architecture design method starts from the preparation phase and then goes through the creative thinking, concept, preliminary design, and detailed design phases of SBC architecture construction. SBC architecture design method uses six fundamental diagrams to formally design the essence of a human-computer interaction system and its details at the same time. In the concept phase, architecture hierarchy diagram and framework diagram are used. In the preliminary design phase, component operation diagram and component connection diagram are used. In the detailed design phase, structure-behavior coalescence diagram and interaction flow diagram are used. With the above six diagrams, we then can effectively design the structure, behavior, and information of human-computer interaction systems; resolve uncertainties and risks caused by those non-architecture-oriented design methods.
