Anchoring Dutch Cultural Heritage Thesauri to WordNet: Two Case Studies

Abstract

In this paper, we argue on the interest of anchoring Dutch Cultural Heritage controlled vocabularies to WordNet, and demonstrate a reusable methodology for achieving this anchoring. We test it on two controlled vocabularies, namely the GTAA thesaurus, used at the Netherlands Institute for Sound and Vision (the Dutch radio and television archives), and the GTT thesaurus, used to index books of the Dutch National Library. We evaluate the two anchorings having in mind a concrete use case, namely generic alignment scenarios where concepts from one thesaurus must be aligned to concepts from the other.
