- 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."

- "Bereits Anfang Dezember 2009 hat das Bundeskabinett die Errichtung der Deutschen Digitalen Bibliothek (DDB) beschlossen, deren Start 2011 erfolgen soll. Kultur- und Medienstaatsminister Bernd Neumann erklärte: »Durch die DDB werden in Zukunft Datenbanken von über 30 000 Kultur- und Wissenschaftseinrichtungen in Deutschland vernetzt und über ein einziges nationales Portal allen Bürgern zugänglich gemacht werden. Sie ist ein Jahrhundertprojekt in der digitalen Welt und leistet einen herausragenden Beitrag zur Bewahrung unserer kulturellen Identität und zum Urheberrechtsschutz.« Vorgesehen ist, dass die DDB digitale Kopien von Büchern, Bildern, Archivalien, Skulpturen, Noten, Musik und Filmen aus Kultur- und Wissenschaftseinrichtungen (Bibliotheken, Archiven, Museen, Mediatheken, Kulturdenkmalen, wissenschaftlichen Instituten et cetara) umfasst. Die DDB ist ein Gemeinschaftsvorhaben von Bund, Ländern und Kommunen. Der Aufbau der zentralen Infrastruktur wird mit Mitteln aus dem Konjunkturprogramm II des Bundes finanziert, der Dauerbetrieb ab 2011 zur Hälfte von Bund und Ländern."
