Artificial Intelligence Lab, Department of MIS, University of Arizona / Identified as an important management concept five years ago (Gamer 1999), knowledge management (KM) aims to enable organizations to capture, organize, and access their intellectual assets. This paper proposes a prototype system that applies a knowledge management approach to support concept-based multimedia information retrieval by integrating various information analysis and image processing techniques. The proposed system uses geographical information as its testbed and aims to provide flexibility to users in terms of specifying their information needs and to facilitate parallel extraction ofinformation in different formats (i.e., text, image). Our testbed selection is based not only on the fact that geographical information has become an important resource supporting organization decision making, but also on the diversity of its information media and the fuzziness of geo-spatial queries. We hope that the proposed system will improve the accessibility of geographical information in different media and provide an example of integrating various information and multimedia techniques to support concept-based cross-media information retrieval.

Tagging has proven attractive to art museums as a means of enhancing the indexing of online collections. This paper examines the state of the art in tagging within museums and introduces the steve.museum research project, and its study of tagging behaviour and the relationship of the resulting folksonomy to professionally created museum documentation. A variety of research questions are proposed and methods for answering them discussed. Experiments implemented in the steve.museum research collaboration are discussed, preliminary results suggested, and further work described.

The quality of metadata in a digital library is an important factor in ensuring access for end-users. Several studies have tried to define quality frameworks and assess metadata but there is little user feedback about these in the literature. As collections grow in size maintaining quality through manual methods becomes increasingly difficult for repository managers. This research presents the design and implementation of a web-based metadata analysis tool for digital repositories. The tool is built as an extension to the Greenstone3 digital library software. We present examples of the tool in use on real-world data and provide feedback from repository managers. The evidence from our studies shows that automated quality analysis tools are useful and valued service for digital libraries.

This brief position statement relates to a more sustained argument presented in published paper, available at: http://dlist.sir.arizona.edu/2477. / This position paper presents and argument for "A Humanities Program," as a contribution to the mapping work for the arts and humanities in information science, prepared for the â Mapping Work in the Arts and Humanities: A Participatory Panel Discussionâ at ASIS&T 2008, organized by SIG-AH. Panelists: Kristin Eschenfelder (moderator and chair). Panelists: Marija Dalbello, Paul Marty, Stephen Paling (panel organizer), Scott Simon, John Walsh, Megan Winget and Lisl Zach.

The presentation was part of The 6th European Networked Knowledge Organization Systems (NKOS) Workshop at the 11th European Conference on Research and Advanced Technology for Digital Libraries (ECDL), Budapest, Hungary September 21, 2007 (http://www.comp.glam.ac.uk/pages/research/hypermedia/nkos/nkos2007/programme.html) / The presentation will briefly introduce a series of major principles for bringing subject terminology to the network level. A closer look at one KOS in particular, the Dewey Decimal Classification, should help to gain more insight into the perceived difficulties and potential benefits of building taxonomy services out and on top of classic large-scale vocabularies or taxonomies.

Annotated bibliography on information visualization for digital librarians. Focuses on overviews of information visualization, key technologies, primary sources, visualization techniques with a digital library application, and materials that are understandable without an engineering background. Some Web-based sources offer demonstration software.

This article discusses the National Science Digital Library (NSDL), a National Science Foundation (NSF) project as an infrastructure or test bed for large-scale and integrated research at the intersections of digital libraries and digital learning. An aggregated evaluation service, modelled on the Text Retrieval Conferences (TREC) and an evaluation materials clearinghouse are starting points for solving the digital learning problem in digital libraries research.

The disciplinary culture theory presumes that if a scholar has been familiar with self-archiving through an existing subject-based repository, this scholar will be more enthusiastic about contributing his/her research to an institutional repository than one who has not had the experience. To test the theory, this article examines self-archiving practices of a group of physicists in both a subject repository and an institutional repository. It does not find a correlation between a disciplinary culture and self-archiving practices.
