A Review of CRIWG Research BIBAKFull-Text 1-15
  Pedro Antunes; José A. Pino
This paper presents a meta-analysis of the CRIWG conference. The study is organized in three main sections: bibliometric analysis, analysis of references and subject analysis. The bibliometric analysis indicates that CRIWG is significantly above the average citation index of similar papers published in LNCS. The analysis of references shows a significant dependence on ACM papers and very low cross-referencing between CRIWG papers. The subject analysis reveals that CRIWG slightly favors positivist evaluations, although almost half of the papers do not present any type of evaluation. We conclude this study with a discussion over strengths, weaknesses, opportunities and threats.
Keywords: Meta-analysis; CRIWG review

Knowledge Elicitation, Construction and Structuring

Supporting Collaborative Knowledge Creation in Mobile Working Scenarios BIBAKFull-Text 16-24
  Gustavo Zurita; Nelson Baloian
Knowledge Creation (KC) is a critical activity inside organizations. It has been said to be a differentiating factor and an important source of competitiveness. Tacit knowledge is an important asset of any organization. Because it is not formalized is difficult to share. KC supporting systems help people inside an organization to share this tacit knowledge. This paper presents the design, and implementation of a KC system called MCKC, for Mobile Collaborative Knowledge Creation, supporting face-to-face knowledge creation and sharing in mobile scenarios, allowing people to create new knowledge and share their tacit knowledge with their co-workers, using visual metaphors, gestures and sketches to implement the human-computer interface.

Collaborative Conceptual Modeling Using an Ontology BIBAKFull-Text 25-32
  Arkalgud Ramaprasad; Steven Diduca; Abhinaya Javier; Tarun Misra; Ganesh Parasuraman; Pratibha Prabhakaran; Himanshu Sharma; Devi Subramanian; Anuroopa Thangaraja; Ankita Vij
This paper describes the method of collaborative conceptual modeling using an ontology. The method was used for the design of a student lifecycle management system at a University. The problem was presented to the students of a Knowledge Management class by the Decision Support staff of the University System. Starting with a core knowledge management framework used for the class the students, in collaboration with the instructor, developed the student lifecycle management ontology to synthesize the requirements. The class presented the ontology to the Assistant VP of Decision Support and her staff for validation, together with prototype dashboards based on the ontology. They found the ontology to be comprehensive, insightful, and useful.

A Mobile Computer System to Support Collaborative Ethnography: An Approach to the Elicitation of Knowledge of Work Teams in Complex Environments BIBAKFull-Text 33-48
  Luiz Carlos L., Jr. Silva; Marcos R. S. Borges; Paulo Victor R. de Carvalho
The paper presents a collaborative ethnography approach for knowledge elicitation of work teams in complex environments. It discusses the concepts of cognitive systems, distributed cognition, and presents a review of methods commonly used in the elicitation of knowledge both in the case of traditional and complex environments. Then, it points to some advantages of a collaborative approach in comparison to other non-collaborative approaches. An evaluation plan of the collaborative ethnography approach based on experimentation, and the development of a mobile system to support the proposed methodology is also presented. This system aims to stimulate collaboration and an organization in the ethnographic knowledge elicitation process.
Keywords: Ethnography; mobile
A Method for Identification and Representation of Business Process Deviations BIBAKFull-Text 49-64
  Lilian Bitton Migon; Marcos R. S. Borges; Maria Luiza Machado Campos
Nowadays, process management represents a fundamental initiative to provide competitive advantages to organizations. The ability to build and operate such processes can provide competitive advantages to these organizations. In this paper, we present an approach for elicitating and discovering problems in business processes that combines the technique of group storytelling with the theory of constraints. This article suggests that group storytelling allows the collection of knowledge to identify the gaps and deviations that exist in business processes, while the theory of constraints provides a language for representing them. We conducted and reported an experimentation of the proposed method in the petroleum field sampling process, with the support of a groupware tool.

Computer Supported Reflection of Good Practice BIBAKFull-Text 65-80
  Till Schümmer; Martin Mühlpfordt; Jörg M. Haake
Knowledge exchange and collaboration in problem solving processes are important factors for learning organizations. Involving practitioners with joint interests in discussions of shared challenges and solutions is an important step in the identification and sharing of good practice. A process facilitating such reflection workshops for practitioners and a tool supporting this process are introduced. The approach is based on computer supported collection of challenges and solution ideas. It uses semantic nets for identifying and connecting practitioners with related interests. First trials show promising results.

Establishing On-Line Corporate Training in Distributed, Synchronous eCollaboration: A Field Study BIBAKFull-Text 81-96
  Tero Päivärinta; Bjørn Erik Munkvold
Whereas technologies for eCollaboration are maturing, a need for learning eCollaboration in distributed organizations continues. This paper presents the experiences from establishing corporate training in distributed, synchronous eCollaboration. The training package was delivered solely on-line with synchronous interaction among the participants and the instructors. The study contributes to the scarce body of research on computer-supported collaborative learning in professional and corporate contexts. The reported experiences illustrate several challenges to establish corporate on-line training of eCollaboration: promotion of awareness of the benefits of learning eCollaboration, management of varying pre-skills of employees participating in distributed and synchronous eCollaboration, lack of common conventions for selecting and using tools for particular organizational eCollaboration scenarios, inclusion of synchronous eCollaboration in the corporate eLearning strategy, and alignment of focused eCollaboration competencies to ever-evolving corporate eCollaboration infrastructure, policies and IT operations.

Decision Support

Integrating Spatial Data and Decision Models in an E-Planning Tool BIBAKFull-Text 97-112
  Pedro Antunes; Cláudio Sapateiro; Gustavo Zurita; Nelson Baloian
We review several decision models to derive six fundamental requirements to collaborative spatial decision-making: perceiving changes in spatial data; retaining interpretation mindsets; externalizing actions and expectancies in spatial data; organizing divergent and convergent working modes; supporting the recognition of situation-action elements; and managing task/pattern structures. A review of the current state of the art shows limited support to some of these requirements, in particular task/pattern and divergent/convergent support. An e-planning prototype was developed to demonstrate the impact of these requirements in collaborative spatial decision-making. Results from a preliminary experiment indicate the prototype enables people to contribute, explain, exteriorize and share their ideas in relation with spatial references.

Supporting the Decision Implementation Process BIBAKFull-Text 113-120
  André Campos; Adriana Santarosa Vivacqua; Marcos R. S. Borges
As the environment becomes competitive, organizations must develop the ability to quickly adapt to changes, becoming flexible and responsive. The decision making process should be quicker and more assertive, leading to action. Organizations need to make the right choices and implement them as decided. It is important that organizations be aware of the implementation of decisions and its impact. Monitoring the implementation of the decision and analyzing its results is the main way of assessing the decisive process itself. Extensive work has been done on decision making, but not on decision implementation. The goal of this research is to increase adherence of the implementation to the decision made. Given that large sums of money are spent on the decision making phase, implementations that do not adhere to the decisions may lead to undesired results, frustrating decision makers. In this paper, we present a method and a system to support decision implementation. With this research, we seek to contribute to the decision making process, specifically during implementation phase.

A Framework and an Architecture for Context-Aware Group Recommendations BIBAKFull-Text 121-128
  Tim Hussein; Timm Linder; Werner Gaulke; Jürgen Ziegler
In this paper, we propose a generic framework to generate context-aware recommendations for both single users as well as groups. We present the concept of context views and a corresponding architecture implementing the framework as well as exemplary recommendation workflows for group recommendations.

Collaboration Support

Concurrent Modeling in Early Phases of the Software Development Life Cycle BIBAKFull-Text 129-144
  Petra Brosch; Philip Langer; Martina Seidl; Konrad Wieland; Manuel Wimmer; Gerti Kappel
Software engineering deals with the development of complex software systems which is an inherently team-based task. Therefore, version control support is needed to coordinate the teamwork and to manage parallel modifications. If conflicting modifications occur, in standard approaches the developer who detected the conflict is responsible for the conflict resolution alone and has to resolve the conflict immediately.
   Especially in early project phases, when software models are typically employed for brainstorming, analysis, and design purposes, such an approach bears the danger of losing important viewpoints of different stakeholders and domain engineers, resulting in a lower quality of the overall system specification. In this paper, we propose conflict-tolerant model versioning to overcome this problem. Conflicts are marked during the merge phase and are tolerated temporarily in order to resolve them later in a collaborative setting. We illustrate the proposed approach for the standardized modeling language UML and discuss how it can be integrated in current modeling tools and version control systems.
Keywords: team-based modeling; model versioning; conflict tolerance
The Integration of Collaborative Process Modeling and Electronic Brainstorming in Co-located Meetings BIBAKFull-Text 145-160
  Thomas Herrmann; Alexander Nolte
Within a workshop, tools and methods have been employed to support process modeling together with creative ideation for identifying the relevant elements of the process. The process-design workshop was part of a project which aims at implementing new ways of data input and transfer for the coordination of services for elderly people. We have chosen tools and methods which seemed to be appropriate to support an efficient process design which integrates creativity and the differing perspectives of the participating stakeholders. This workshop led to a case study which revealed strengths and weaknesses of our approach and helped us to identify further recommendations and requirements for the integration of collaborative modeling and creativity support.

Integrating Context-Enriched Explanations and Communication in an Adaptive Collaboration Environment BIBAKFull-Text 161-168
  Syed Sajid Hussain; Dirk Veiel; Jörg M. Haake; Stephan Lukosch
Distributed collaboration among teams involves dynamically changing situations. Making collaboration environment fit the needs of these situations is supported by system-initiated adaptation based on user and team context. Such adaptations may confuse the users, because they cannot remember all adaptation policies. In this paper we propose an approach to present context-enriched explanations to help them understand the adaptation behavior. Also, we describe a social network analysis strategy to identify socially related and current situation relevant communication partners. Integrated on demand communication is facilitated among these partners for discussion and learning about adaptation policies.

A Tool for Training Students and Engineers in Global Software Development Practices BIBAKFull-Text 169-184
  Miguel J. Monasor; Aurora Vizcaíno; Mario Piattini
Global Software Development (GSD) is an emerging trend in which virtual teams work on the same projects at a distance. Despite the advantages of this shift, the collaboration between distant members becomes more difficult. Team members interact by using collaborative tools, and this collaboration is affected by time, cultural and language differences. These drawbacks lead to the need to train students and software engineers in the new collaborative skills required.
   These skills can only be trained by involving learners in practical experiences, but this is not always possible since it necessitates collaboration with distant institutions (universities/firms). We have focused our work on the development of a tool with which to train these skills through the use of a virtual training environment for GSD that avoids this difficulty by placing learners in virtual GSD scenarios in which they will develop the skills needed to work on global software projects.

Awareness Support in Global Software Development: A Systematic Review Based on the 3C Collaboration Model BIBAKFull-Text 185-201
  Igor Steinmacher; Ana Paula Chaves; Marco Aurélio Gerosa
The developers' physical distribution in Global Software Development (GSD) imposes challenges related to awareness support during collaboration. In this paper, we present a systematic review of the literature that describes studies that improve awareness support in a GSD scenario, identifying which of the dimensions of the 3C model, namely communication, coordination, and cooperation, are supported by these studies. Results indicate that coordination is far the most explored dimension, while awareness support in communication is very poorly studied. The research also identified a high number of tools introduced in the GSD domain and some new research opportunities.

Awareness Checklist: Reviewing the Quality of Awareness Support in Collaborative Applications BIBAKFull-Text 202-217
  Pedro Antunes; Cláudio Sapateiro; José A. Pino; Valeria Herskovic; Sergio F. Ochoa
A proposal of a method to assess awareness support is made. This proposal is intended for the use of collaborative applications developers at any time during development. It consists of a checklist. It is made with the inclusion of design elements obtained by the analysis of Quality Assurance ideas applied to collaborative systems. The proposal is illustrated with its use in two cases.

Supporting Asynchronous Workspace Awareness by Visualizing the Story Evolution in Collaborative Storytelling BIBAKFull-Text 218-232
  Jana Schumann; Tanja Buttler; Stephan Lukosch
Workspace awareness support is mandatory for group support systems. In this paper, we present a novel approach to asynchronous awareness by means of traceability support. We integrate and evaluate our approach in the web portal of CASTing, a tool for audio-based collaborative storytelling. We describe the development of a prototype that visualizes how the collaborative story evolved over time. Our visualization helps group members assess who has modified the shared story, what exactly has been modified and when it has been modified. We evaluate different awareness factors in an experiment. The experiment proved that our visualization approach enables users to acquire workspace awareness by accessing information about previous work of other users.

Groupware Design

Dealing with Device Collaboration Rules for the PCSCW Model BIBAKFull-Text 233-248
  Kahina Hamadache; Luigi Lancieri
In this paper, we describe the design, the development and the use of devices collaboration rules for the PCSCW (Pervasive Computing Supported Collaborative Work) Model. These rules rely on the precise description of roles, tasks, actions, resources required by these actions and constraints associated to these resources to select the proper way to make devices cooperate with the final objective to facilitate the collaboration of humans. We suggest that by defining constraints on resources as triplets composed of a parameter, a value and an associated criticality it allows us to quantify, estimate, compare and then choose between several candidate rules. The finality given by these rules is a simple but efficient way to make devices choose automatically the most appropriate way to cooperate.

Enabling Collaboration Transparency with Computational Reflection BIBAFull-Text 249-264
  Pedro García López; Enrique Fernández-Casado; Carles Angles; Maria Ferre
The conversion of legacy single-user applications to collaborative multi-user tools is a recurrent topic in groupware settings. Many works tried to achieve collaboration transparency: to enable collaborative features without modifying the source code of the single-user application. In this paper, we present a novel blackbox solution that achieves complete transparency by intercepting user interface libraries and input events. This is the first blackbox solution constructed on top of lightweight wrapper technologies (Aspect Oriented Programming) and unlike previous approaches it provides support to both AWT and Swing applications. Our solution solves four important problems: event broadcasting, management of external resources (random numbers), contextual information (telepointers) and transparent launching support. We validated our approach with several Swing-based and AWT-based tools demonstrating that our wrapper is generic and imposes very low overhead.
Plasticity of Interaction Interfaces: The Study Case of a Collaborative Whiteboard BIBAKFull-Text 265-280
  Gabriela Sánchez; Sonia Mendoza; Dominique Decouchant; Lizbeth Gallardo-López; José Rodríguez
The development of plastic user interfaces constitutes a promising research topic. They are intentionally designed to automatically adapt themselves to changes of their context of use defined in terms of the user (e.g., identity and role), the environment (e.g., location and available information/tools) and the platform. Some single-user systems already integrate some plasticity capabilities, but this topic remains quasi-unexplored in CSCW. This work is centered on prototyping a plastic collaborative whiteboard that adapts itself: 1) to the platform, as it can be launched from heterogeneous computer devices and 2) to each collaborator, when he is working from several devices. This application can split its interface between the users' devices in order to facilitate the interaction. Thus, the distributed interface components work in the same way as if they were co-located within a unique device. At any time, group awareness is maintained among collaborators.

Developing a Framework of Common Information Space (CIS): Grounded Theory Analysis of Airport CIS BIBAKFull-Text 281-296
  Nallini Selvaraj; Bob Fields
The notion of Common Information Space (CIS) has been proposed in the field of Computer Supported Cooperative Work (CSCW) as a conceptual framework for analyzing cooperative work processes. The area is still in its formative years and requires more research to contribute to its development. This paper presents findings from an investigation undertaken for such an endeavor. Three perceptions of CIS are presented, which are, CIS as a socio-technical arrangement, dynamic arrangement, and dependency management arrangement. These have been derived from review of existing research contributing to CIS notion development and Grounded Theory analysis of collaborative work process in air traffic control setting. The findings presented in this paper provide a comprehensive and consolidated view of the notion development. The paper contributes to the ongoing discussion of CIS notion development by making theoretical as well as methodological contribution.

Social Networking

The Mind's Eye on Personal Profiles: How to Inform Initial Trustworthiness Assessments in Virtual Project Teams BIBAKFull-Text 297-304
  Ellen Rusman; Jan van Bruggen; Peter B. Sloep; Martin Valcke; Rob Koper
Personal information is an important precursor for the trust formation process in virtual project teams. However, till today it has remained unclear what specific personal information most trustors prefer. Insight in their preferences as well as in their foundation could support the development of templates that provide communication support to virtual teams. In this paper, we describe and empirically test an approach that links trustors' common information preferences and a TrustWorthiness' ANtecedents (TWAN) framework. Thus, we provide 'the mind's eye' on interpreting and valuing information elements.

Supporting Informal Interaction in a Hospital through Impromptu Social Networking BIBAKFull-Text 305-320
  Alberto L. Morán; Juan Rodríguez-Covili; David A. Mejia; Jesús Favela; Sergio F. Ochoa
Social networking systems allow users to keep in touch with relatives and friends in the absence of physical proximity. These tools are also increasingly supporting productive interactions in diverse working environments. In this paper, based on the understanding of informal communication in hospitals, we identify opportunities for the use of social networking software in support of hospital work. This has inspired the design of meetU, a tool aimed at supporting impromptu social networking through an ad-hoc communication infrastructure. The services offered by the system are illustrated through interaction scenarios, which were also used to evaluate the system with a group of medical interns.

Ambient Displays for Integrating Older Adults into Social Networking Sites BIBAKFull-Text 321-336
  Raymundo Cornejo; Jesús Favela; Monica Tentori
Social networking sites (SNS) help users sustain and strengthen ties with friends and relatives. However older adults who are less technically inclined individuals are often left aside these SNS felling as outsiders within their own family that uses this media to socialize. To assist these non-technical older adults we developed two ambient displays aimed at seamlessly integrate them into SNS. The first prototype, ePortrait, shows to older adults the photographs uploaded by their relatives in a SNS and the second prototype, eBowl, provides means to communicate their status through the manipulation of physical objects. The results of an evaluation shows that ambient displays are capable of monitoring older adults' context and provide them with continuous information about their social network in a subtle, peripheral and expressive manner. As a consequence, older adults use the information conveyed by such displays to enhance conversations with new topics helping them feel more integrated with their family.

Mobile Collaboration

A Simple and Portable Command Post to Coordinate Search and Rescue Activities in Disaster Relief Efforts BIBAKFull-Text 337-344
  Rodrigo Bartels; Valeria Herskovic; Alvaro Monares; Sergio F. Ochoa; José A. Pino; Marcos R. S. Borges
The lack of communication channels and support information can make the critical search and rescue of survivors after a disaster an ineffective process resulting in losses. This work addresses this problem by proposing a simple and portable command post application based on mobile devices and ad-hoc networks. The application provides support to communication and collaboration aiming to speed up the SAR process. The system architecture and some implementation issues are also presented.

Digital Workbook: A Mobile Learning Environment to Support Collaborative Examinations BIBAKFull-Text 345-352
  Iván D. Claros; César A. Collazos; Luis A. Guerrero; Sergio F. Ochoa
It is already known that some collaborative assessment processes can provide students not only the possibility to show how well they have understood knowledge content, but also the opportunity to enhance and increase such knowledge. Such learning activities also allow instructors to diagnose the quality of the instructional process. However there is evidence that this type of activities involve an important effort. This article presents a mobile learning environment named digital workbook, which was designed to support students and instructors when applying a Collaborative Examination Technique. The tool was evaluated in a Computer Science undergraduate course, and the obtained results are highly encouraging.

Evaluating a Prototype for Geo-referenced Collaborative Psychotherapy with Mobile Devices BIBAKFull-Text 353-362
  Luís Carriço; Gustavo Zurita; Marco de Sá; Nelson Baloian; João Faria; Isabel
Social competency training, as part of psychotherapy, for children and teenagers, requires them to engage on outdoor activities in which they have to complete tasks such as talking to someone or visiting a specific place. Currently, the inability for therapists to monitor their patients, to promote collaborative efforts and to reinforce positive attitudes is a major issue that affects both the therapy process and its results. In this paper we present an evaluation experience of a mobile prototype for a geo-referenced collaborative system that supports in-situ group therapy. The system aims to provide means for therapists to monitor their patients, their locations and achievements and includes communication mechanisms that facilitate cooperation between patients and therapist. We describe the concept behind the project, our initial low-fidelity prototypes and the experiments that were undertaken to validate them. Initial results are discussed and future work is defined.
