- Abstract
- Grounded on a strong belief that ontologies enhance the performance of information retrieval systems, there has been an upsurge of interest in ontologies. Its importance is identified in diverse research fields such as knowledge engineering, knowledge representation, qualitative modeling, language engineering, database design, information integration, object-oriented analysis, information retrieval and extraction, knowledge management and agent-based systems design (Guarino, 1998). While the role-played by ontologies, automatically lends a place of legitimacy for these tools, research in this area gains greater significance in the wake of various challenges faced in the contemporary digital environment. With the objective of overcoming various pitfalls associated with current search mechanisms, ontologies are increasingly used for developing efficient information retrieval systems. An indicator of research interest in the area of ontology is the Swoogle, a search engine for Semantic Web documents, terms and data found on the Web (Ding, Li et al, 2004). Given the complex nature of the digital content archived in digital libraries, ontologies can be employed for designing efficient forms of information retrieval in digital libraries. Knowledge representation assumes greater significance due to its crucial role in ontology development. These systems aid in developing intelligent information systems, wherein the notion of intelligence implies the ability of the system to find implicit consequences of its explicitly represented knowledge (Baader and Nutt, 2003). Knowledge representation formalisms such as 'Description Logics' are used to obtain explicit knowledge representation of the subject domain. These representations are developed into ontologies, which are used for developing intelligent information systems. Against this backdrop, the paper examines the use of Description Logics for conceptually modeling a chosen domain, which would be utilized for developing domain ontologies. The knowledge representation languages identified for this purpose are Web Ontology Language (OWL) and KArlsruhe ONtology (KAON) language. Drawing upon the various technical constructs in developing ontology-based information systems, the paper explains the working of the prototypes and also presents a comparative study of the two prototypes.

- "1. The EU projeet Renardus Renardus is a project funded by the European Commission as part of the Information Society Technologies (IST) programme, part of the European Union's 5th Framework Programme. Partners in Renardus include national libraries, research centres and subject gateway services from Denmark, Finland, Germany, The Netherlands, Sweden and the UK, co-ordinated by the National Library of the Netherlands. The project aims to develop a Web-based service to enable searching and browsing across a range of distributed European-based information services designed for the academic and research communities - and in particular those services known as subject gateways. These gateways are services that provide access to Internet resources. They tend to be selective with regard to the resources they give access to, and are usually based an the manual creation of descriptive metadata. Services typically provide users with both search and browse facilities, and offen offer hierarchical browse structures based an subject classification schemes (Koch & Day, 1997). Predecessor projects like the EU project DESIRE have already developed solutions for the description of individual resources and for automatic classification at the level of an individual subject gateway using established classification systems. Renardus intends to develop a service that can cross-search and cross-browse a number of distributed subject gateways through the use of a common metadata profile and by the mapping all locally-used classification schemes to a common scheme. A thorough review of existing data models (Becker, et al., 2000) was used as the basis for the agreement of a minimum set of Dublin Core-based metadata elements that could be utilised as a common data model. A comprehensive mapping effort from the individual gateways' metadata element sets and content encoding schemes to the common profile has taken place. This provides the infrastructure for interoperability between all participating databases and thus is the necessary prerequisite for cross-searching."

- Abstract
- The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.
