Abstract

Information provision via digital libraries often separates the writing process from that of information searching. In this paper we investigate the potential of a tighter integration between searching for information in digital libraries and using those results in academic writing. We consider whether it may sometimes be advantageous to encourage searching while writing instead of the more conventional approach of searching first and then writing. The provision of ambient search is explored, taking the user's ongoing writing as a source for the generation of search terms used to provide possibly useful results. A rapid prototyping approach exploiting web services was used as a way to explore the design space and to have working demonstrations that can provoke reactions, design suggestions and discussions about desirable functionalities and interfaces. This design process and some preliminary user studies are described. The results of these studies lead to a consideration of issues arising in exploring this design space, including handling irrelevant results and the particular challenges of evaluation.

Abstract

We describe how to support the process of collaborative browsing and how to integrate support for the social aspects of information searching activities into information systems and particularly their interfaces. The use of library resources is often stereotyped as a solitary activity. However, informal observations indicate significant collaboration between users despite the fact that existing systems fail to support this. We describe the Ariadne system which does attempt to support collaboration by providing a visualization of the search process. Storage of search histories as digital object allows them to be manipulated and communicated. An explicit representation of a search history supports discussion of search strategies and concepts by explicit pointing to prior activities even when one of the participants may be a novice lacking the appropriate vocabulary. Several different types of activity, synchronous and asynchronous, remote and co-located, can be supported by search process re-use. We outline some of the issues of privacy concerned with the storage of users' searches

Abstract

Collaboration is an important aspect of searching online information retrieval systems that requires explicit computerized support. Surveys a number of systems offering varied approaches to supporting collaboration and applies a strucutre for analysing the various aspect of collaboration. The dominant form of collaboration in digital libraries is likely to be remote and asynchronous. Collaborative work in the digital library requires that both the search product and the search process can be captured and communicated. Introduces the ARIADNE system as an example of computerized support for collaboration between bowsers

Abstract

Current institutional repository software provides few tools to help metadata librarians understand and analyse their collections. In this paper, we compare and contrast metadata analysis tools that were developed simultaneously, but independently, at two New Zealand institutions during a period of national investment in research repositories: the Metadata Analysis Tool (MAT) at The University of Waikato, and the Kiwi Research Information Service (KRIS) at the National Library of New Zealand. The tools have many similarities: they are convenient, online, on-demand services that harvest metadata using OAI-PMH, they were developed in response to feedback from repository administrators, and they both help pinpoint specific metadata errors as well as generating summary statistics. They also have significant differences: one is a dedicated tool while the other is part of a wider access tool; one gives a holistic view of the metadata while the other looks for specific problems; one seeks patterns in the data values while the other checks that those values conform to metadata standards. Both tools work in a complementary manner to existing web-based administration tools. We have observed that discovery and correction of metadata errors can be quickly achieved by switching web browser views from the analysis tool to the repository interface, and back. We summarise the findings from both tools' deployment into a checklist of requirements for metadata analysis tools.

Abstract

"How to Build a Digital Library" is the only book that offers all the knowledge and tools needed to construct and maintain a digital library, regardless of the size or purpose. It is the perfectly self-contained resource for individuals, agencies, and institutions wishing to put this powerful tool to work in their burgeoning information treasuries. The second edition reflects new developments in the field as well as in the Greenstone Digital Library open source software. In Part I, the authors have added an entire new chapter on user groups, user support, collaborative browsing, user contributions, and so on. There is also new material on content-based queries, map-based queries, cross-media queries. There is an increased emphasis placed on multimedia by adding a 'digitizing' section to each major media type. A new chapter has also been added on 'internationalization', which will address Unicode standards, multi-language interfaces and collections, and issues with non-European languages (Chinese, Hindi, etc.). Part II, the software tools section, has been completely rewritten to reflect the new developments in Greenstone Digital Library Software, an internationally popular open source software tool with a comprehensive graphical facility for creating and maintaining digital libraries. As with the First Edition, a web site, implemented as a digital library, will accompany the book and provide access to color versions of all figures, two online appendices, a full-text sentence-level index, and an automatically generated glossary of acronyms and their definitions. In addition, demonstration digital library collections will be included to demonstrate particular points in the book. To access the online content please visit our associated website. This title outlines the history of libraries - both traditional and digital - and their impact on present practices and future directions. It is written for both technical and non-technical audiences and covers the entire spectrum of media, including text, images, audio, video, and related XML standards. It is web-enhanced with software documentation, color illustrations, full-text index, source code, and more.
