A Method for Converting Thesauri to RDF/OWL

This page supplements a paper that describes a method to convert thesauri to RDF and OWL.

The results of the case studies presented in that paper are published here. The cases concern conversions of two thesauri: MeSH (Medical Subject Headings) and WordNet.

Case 1: MeSH (Medical Subject Headings)

The original XML source and DTDs (2004 version) can be downloaded from National Laboratory of Medicine download section. Note that only the XML files for Descriptors and Qualifiers (and associated DTD) were converted. XSLT was used to convert the original XML to RDF/OWL.

Step 1a Step 1b Step 2a Step 2b Step 3
Schema mesh1a.rdfs mesh1b.rdfs mesh2a.owl mesh2b.owl mesh3.owl
Data mesh1a.rdf (129 MB) mesh1b.rdf (125 MB) N/A N/A N/A
Conversion mesh.zip N/A N/A N/A N/A

Case 2: WordNet

The original Prolog source (release 2.0) can be downloaded from WordNet download section. Prolog programs (SWI-Prolog) were written for the conversion from Prolog data to RDF/OWL. Recent SWI-Prolog distributions include a semantic web library, which is used in the conversion programs.

Data wordnet1a.rdf (47 MB) N/A N/A N/A N/A
