WO3: Acquisition Of Lexical Information

We describe here a procedure to combine two different existing techniques for Ontology Enrichment with domain-specific concepts. The resulting algorithm is fully unsupervised, and the level of precision is higher than when they are used separately, so we believe that both algorithms benefit from each other. The experiments have been performed by extending WordNet with concepts extracted from "The Lord of the Rings"
