Results of the OAEI 2007 Library Thesaurus Mapping Task

The evaluation was done according to three scenarios. For each scenario, this page presents the raw results that were obtained. For further details, we refer the reader to this report (a longer, more technical version of the Library section included in the OAEI report) and to the slides presented at the Ontology Matching workshop.

The results sent by the three participants are available in the data section of the track.

DSSim (exactMatch) 13.4 31

Results for the annotation translation (book re-indexing) scenario

Results for the automated evaluation, using a gold standard of books indexed against both GTT and Brinkman thesauri:
