Constructing a Corpus-based Ontology using Model Bias. FLAIRS 2006

Recent work in lexical resource construction has recog-nized the importance of contextualizing the knowledge in existing resources and ontologies with information derived from text corpora. This paper describes the in-tegration of a corpus-based lexical acquisition process with a large, linguistically motivated lexical ontology. This semi-automatic bootstrapping process is used to produce refinements, additions, and modifications to the type specifications for the arguments to predicates in this ontology. In addition, the procedure is used to ver-ify and modify the lexical extensions of the entity types in the ontology
