Methods for Porting Resources to the Semantic Web

Abstract

Abstract. Ontologies will play a central role in the development of the Semantic Web. It is unrealistic to assume that such ontologies will be developed from scratch. Rather, we assume that existing resources such as thesauri and lexical data bases will be reused in the development of ontologies for the Semantic Web. In this paper we describe a method for converting existing source material to a representation that is compatible with Semantic Web languages such as RDF(S) and OWL. The method is illustrated with three case studies: converting Wordnet, AAT and MeSH to RDF(S) and OWL.

GenTax: A Generic Methodology for Deriving OWL and RDF-S Ontologies from Hierarchical Classifications, Thesauri, and Inconsistent Taxonomies

“…[15] shows the reuse and semantic enrichment of an existing hierarchical standard, and demonstrates this for the Art and Architecture Thesaurus (AAT). [16] and [8] are consequent works of this stream of research. An important characteristic of [16] and [8] is that the authors leave the limits of OWL DL in order to capture semantics contained in the original thesaurus, namely to be able to treat classes as instances and vice versa.…”

An important characteristic of [16] and [8] is that the authors leave the limits of OWL DL in order to capture semantics contained in the original thesaurus, namely to be able to treat classes as instances and vice versa. [9] presents a formal theory of classifications; [17] is an extension of this work and proposes how lightweight ontologies can be derived from such specifications.…”

Bringing the IPTC News Architecture into the Semantic Web

“…The "SKOSification" of thesauri in the cultural heritage domain has lead to a general method for porting thesauri to the Semantic Web [22,3,2]. This method advocates four steps (preparation, syntactic conversion, semantic conversion, standardization) and provides a number of guidelines for each step.…”

A Methodology for Deriving OWL Ontologies from Products and Services Categorization Standards

“…Wielinga et al (2001) show the reuse and semantic enrichment of an existing taxonomy and demonstrates this for the Art and Architecture Thesaurus (AAT). Wielinga et al (2004) and van Assem et al (2004) are consequent works of this stream of research. An important characteristic of Wielinga et al (2004) and van Assem et al (2004) is that they leave the limits of OWL DL in order to capture semantics contained in the original taxonomy, namely to be able to treat classes as instances and vice versa.…”

An important characteristic of Wielinga et al (2004) and van Assem et al (2004) is that they leave the limits of OWL DL in order to capture semantics contained in the original taxonomy, namely to be able to treat classes as instances and vice versa. An important distinction between the proposal of Wielinga et al (2004) and the work presented in our paper is that they treat the taxonomic relationship in the input taxonomy as a special form (i.e.…”
