evaluation of the navigation effectiveness of an organizational taxonomy built on a general classification scheme and domain Thesauri
Association for Information Science and Technology, 2014Co-Authors: Zhonghong Wang, Christopher S G Khoo, Abdus Sattar ChaudhryAbstract:This paper presents an evaluation study of the navigation effectiveness of a multifaceted organizational taxonomy that was built on the Dewey Decimal Classification and several domain Thesauri in the area of library and information science education. The objective of the evaluation was to detect deficiencies in the taxonomy and to infer problems of applied construction steps from users' navigation difficulties. The evaluation approach included scenario-based navigation exercises and postexercise interviews. Navigation exercise errors and underlying reasons were analyzed in relation to specific components of the taxonomy and applied construction steps. Guidelines for the construction of the hierarchical structure and categories of an organizational taxonomy using existing general classification schemes and domain Thesauri were derived from the evaluation results.

using classification schemes and Thesauri to build an organizational taxonomy for organizing content and aiding navigation
Journal of Documentation, 2008Co-Authors: Zhonghong Wang, Abdus Sattar Chaudhry, Christopher S G KhooAbstract:Purpose – Potential and benefits of classification schemes and Thesauri in building organizational taxonomies cannot be fully utilized by organizations. Empirical data of building an organizational taxonomy by the top‐down approach of using classification schemes and Thesauri appear to be lacking. The paper seeks to make a contribution in this regard.Design/methodology/approach – A case study of building an organizational taxonomy was conducted in the information studies domain for the Division of Information Studies at Nanyang Technology University, Singapore. The taxonomy was built by using the Dewey Decimal Classification, the Information Science Taxonomy, two information systems taxonomies, and three Thesauri (ASIS&T, LISA, and ERIC).Findings – Classification schemes and Thesauri were found to be helpful in creating the structure and categories related to the subject facet of the taxonomy, but organizational community sources had to be consulted and several methods had to be employed. The organization...

a method to convert Thesauri to skos
Lecture Notes in Computer Science, 2006Co-Authors: M F J Van Assem, Veronique Malaise, Alistair Miles, A T SchreiberAbstract:Thesauri can be useful resources for indexing and retrieval on the Semantic Web, but often they are not published in RDF/OWL. To convert Thesauri to RDF for use in Semantic Web applications and to ensure the quality and utility of the conversion a structured method is required. Moreover, if different Thesauri are to be interoperable without complicated mappings, a standard schema for Thesauri is required. This paper presents a method for conversion of Thesauri to the SKOS RDF/OWL schema, which is a proposal for such a standard under development by W3Cs Semantic Web Best Practices Working Group. We apply the method to three Thesauri: IPSV, GTAA and MeSH. With these case studies we evaluate our method and the applicability of SKOS for representing Thesauri.

Integrating ontologies and Thesauri for RDF schema creation and metadata querying
International Journal on Digital Libraries, 2000Co-Authors: Bernd Amann, Irini Fundulaki, Michel SchollAbstract:In this paper we present a new approach for building metadata schemas by integrating existing ontologies and structured vocabularies (Thesauri). This integration is based on the specification of inclusion relationships between thesaurus terms and ontology concepts and results in application-specific metadata schemas incorporating the structural views of ontologies and the deep classification schemes provided by Thesauri. We will also show how the result of this integration can be used for RDF schema creation and metadata querying. In our context, (metadata) queries exploit the inclusion semantics of term relationships, which introduces some recursion. We will present a fairly simple database-oriented solution for querying such metadata which avoids a (recursive) tree traversal and is based on a linear encoding of thesaurus hierarchies.

Integrating Ontologies and Thesauri to Build RDF Schemas
1999Co-Authors: Bernd Amann, Irini FundulakiAbstract:In this paper we present a new approach for building RDF schemas by inte-grating existing ontologies and structured vocabularies (Thesauri). We will present a simple mechanism based on the specification of inclusion relationships between thesaurus terms and ontology concepts and show how these relationships can be exploited to create application-specific RDF schemas incorporating the structural views of ontologies and deep classification schemes provided by Thesauri.
