The North Carolina State Government Website Archives: A case study of an American government Web archiving project BIBAFull-Text 7-26
  Kristin E. Martin; Kelly Eubank
The North Carolina State Archives and State Library of North Carolina collaborated to develop the North Carolina State Government Website Archives, a collection of captured government websites dating back to the fall of 2005 and available to the public for research. This paper explores the process by which the Web archives were developed -- from the methodology of how to collect information on the Web through the selection process for determining material to be included in the Web archives and the choice of Archive-It, a service available through the Internet Archive, as the technology for running the Web archives. Challenges in the development and deployment of the Web archives are discussed, including controlling the growth of material captured, the capture of unwanted content, managing robots.txt exclusions, and educating state agencies about the importance of websites as government records. The Web archives are available at http://www.ah.dcr.state.nc.us/archives/webarchives/index.html
Czech Web archive analysis BIBAFull-Text 27-37
  P. Zabicka; L. Matejka
This paper introduces current activities of WebArchiv, a Web archiving project of the National Library in Prague. It also presents an analysis of the archive of Czech Web resources built by the project team. Through this analysis, we suggest several Web-harvesting strategies that would help to reduce costs associated with maintaining large amounts of data.
AONS -- An obsolescence detection and notification service for Web archives and digital repositories BIBAFull-Text 39-53
  J. Curtis; P. Koerbin; P. Raftos; D. Berriman; J. Hunter
This paper describes the results of a collaboration between the University of Queensland, the Australian National University and the National Library of Australia which has developed and deployed an automatic obsolescence detection and notification service (AONS) for digital collections. AONS can be configured to run over different types of collections of digital objects -- either institutional repositories (DSpace or Fedora) or Web archives such as the National Library's PANDORA ('Preserving and Accessing Networked DOcumentary Resources of Australia') Archive. This work represents a real-world implementation of the obsolescence detection and notification service originally developed within the University of Queensland's PANIC Project. PANIC (Preservation and Archival of New media and Interactive Collections) was a prototype system based on a semantic Web services architecture which was designed to semi-automate the preservation of digital collections. This paper describes how AONS can be configured to automatically monitor collections for format obsolescence and streamline the subsequent migration of 'at risk' digital objects to current recommended formats, enabling their long-term preservation and accessibility.
Annotating Web archives -- structure, provenance, and context through archival cataloguing BIBAFull-Text 55-75
  P. H. J. Wu; A. K. H. Heok; I. P. Tamsir
Despite the success of Internet access via search technology, such ease of access is still not available in Web archives, as a greater amount of relevant contextual information is essential in accessing Web archives. The degree of relevance of the contextual information has to be customized to suit research on culture and heritage study over time. Information scientists have long been struggling to find a system that can help them organize Web archives so that users can have access to complete and coherent collections. Lessons can be learned from archivists who have an established tradition of linking materials to its origin and ownership or what is termed provenance. In this paper, we demonstrate how Web Annotation for Web Intelligence, more than just an intuitive way of expressing one's thoughts on the materials under study, is in fact an appropriate tool for cataloguing Web archives in order to ensure a high quality of access for users. Informed by the theory of Records Continuum, a demonstration of access to archived Web materials will be presented. We then recommend an effective way of allowing the continual organization of Web archives based on several design principles for a Web annotation system. This system would preserve the evidence and context of the cataloguing process. Such a tool would also help facilitate collaboration among information professionals in organizing complex Web archives. Implementing the recommended Web annotation system will help ensure better-quality archives with more evidence and contextual information preserved within the system.
Towards mining past content of Web pages BIBAFull-Text 77-86
  A. Jatowt; K. Tanaka
While much attention has recently focused on preserving the past content of the Web, there is still a lack of efficient tools for utilizing data stored in Web archives. Web archives constitute large data sources that could be extensively analysed and mined for knowledge discovery. In this paper, we describe the issues involved with mining Web archive data. We discuss several concepts related to collecting and analysing historical content of Web pages and briefly describe two knowledge discovery tasks -- temporal summarization and object history detection.

Pervasive learning games: A comparative study BIBAFull-Text 93-116
  Francika Markovic; Otto Petrovic; Cristian Kittl; Bernhard Edegger
This paper investigates how pervasive games can be used for an efficient transfer of knowledge in learning situations. Pervasive games present an innovative game model which merges the real world and the virtual world. In the present study, this game concept is used in conjunction with mobile phones as a means of interaction and communication enablers to support learning. The paper presents the design of a new pervasive learning game, which was compared with a conventional case-study approach in an empirical study with 100 students in respect to long-term learning results and learning efficiency. The empirical results reveal that the pervasive game leads to higher energetic activation, more positive emotions, and more positive attitudes towards learning content, than the conventional case-study approach.
A study of teachers' use of online learning resources to design classroom activities BIBAFull-Text 117-134

While much progress has been made on the technical design and development of digital libraries, much less is known about how and why education digital library content and associated tools can support and enhance the activities of educators in their professional work. This article elaborates a conceptual framework that characterizes teachers' practices when using online learning resources (called 'teaching as design'), and a professional development model aimed at increasing teachers' capacity for designing learning activities in the context of authentic practice. Findings from two workshop implementations showed positive impacts on teachers' knowledge, attitudes, and subsequent behaviours using online learning resources. An analysis of teacher created activities indicates a relationship between the form of design (offload, adaptation, or improvisation) and the granularity of the learning objects utilized in the activity.
Representing Collections as Compositions to support distributed creative cognition and situated creative learning BIBAFull-Text 135-162
  A. Kerne; E. Koh
We investigate how the creativity support tool combinFormation supports the creativity-oriented course, The Design Process, by representing collections as compositions. Undergraduate students in The Design Process are charged with working in interdisciplinary teams to develop new inventions. combinFormation is a mixed-initiative system that integrates browsing, searching, representing, manipulating, and collecting digital information resources, using the form of the visual composition space. Students use the composition space to develop collections of prior work that support their creative processes of developing new inventions. A quantitative study shows the overall effect of mixed-initiative composition on the performance of student groups on creative projects. To understand the mechanisms of situated creativity support, we follow-up with case-study interviews of two project teams. We develop the frameworks of distributed creative cognition and situated creative learning to analyse the interview data. We find that the mixed-initiative capabilities of procedural generation and human manipulability of visual information representations in the composition space support distributed creative cognition and situated creative learning.
Designing for privacy in personal learning spaces BIBAFull-Text 163-185
  M. Najafian Razavi; L. Iverson
We present the results of a study of information sharing behaviour of the users of a personal learning space. Our study uses grounded theory methodology and involves 12 K12 students who have used a personal learning space for over a year. The resulting grounded theory suggests that users' preferences regarding privacy of their artefacts in such an environment depends on a number of factors, including the current stage in the artefact's life cycle, the nature of trust between the owner and the receiver of information, and the dynamics of the group or community within which the information is being shared. Based on our findings, we propose a framework for understanding and designing privacy control mechanisms for personal learning spaces that reflect users' mental model of information privacy. To illustrate these principles in practice, we describe the privacy management mechanisms of OpnTag, an application we have designed as a test bed for social information management.
Collaborative Learning in a Wiki Environment: Experiences from a software engineering course BIBAFull-Text 187-209
  Shailey Minocha; Peter G. Thomas
The post-graduate course, Software Requirements for Business Systems, in the Department of Computing of the Open University involves teaching systematic elicitation and documentation of requirements for software systems. On a software development project, team members often work remotely from one another and increasingly use wikis to collaboratively develop the requirements specification. In order to emulate requirements engineering practice, the course has been enhanced to include group collaboration using a wiki. In this paper, we describe the wiki-based collaborative activities and the evaluation of the pedagogical effectiveness of a wiki for collaborative learning. Our evaluations have confirmed that the strength of a wiki, as a collaborative authoring tool, can facilitate the learning of course concepts and students' appreciation of the distributed nature of the RE process context. However, there is a need to support the discussion aspects of collaborative activities with more appropriate tools. We have also found that there are certain usability aspects of wikis that can mar a positive student experience. This paper will be of interest to academics aspiring to employ wikis on their courses and to practitioners who wish to realize the potential of wikis in facilitating information sharing, knowledge management, and in fostering collaboration within and between organizations.
REASE -- The repository for learning units about the Semantic Web BIBAFull-Text 211-237
  Jörg Diederich; Martin Dzbor; Diana Maynard
REASE, EASE's repository for Semantic Web learning units, is a unique repository containing a diverse set of learning resources, ranging from annotated slides to video recordings, and from one-hour tutorials to fully-fledged university courses, for both academic and industrial audiences. It aims to accommodate the heterogeneous requirements of different users trying to learn about the Semantic Web. This article provides an introductory description of REASE, and describes the lessons learnt while creating and designing the repository, based on a mixed-method evaluation involving actual REASE users, a clean-room evaluation, and usage statistics gained from a transaction log analysis.
Seekers, sloths and social reference: Homework questions submitted to a question-answering community BIBAFull-Text 239-248
  R. Gazan
An increasing number of students are seeking homework help outside library structures and systems, such as on social reference sites, where questions are answered by online community members who rate one another's answers and provide collaborative filtering in place of traditional expertise. This paper reports the preliminary results of a participant observation and content analysis of homework questions submitted to Answerbag, a social reference site with over one million unique visitors per month. The results suggest that members of the online community are able to distinguish between questions submitted by Seekers -- those who interact with the community and engage in conversation about their questions -- and Sloths, those who post their homework questions apparently verbatim and interact no further. How the community reacts to these distinct types of questioners reflects values similar to those of professional reference providers, and the community structure also allows members to educate questioners about community standards and the ethics of information seeking.
