Re: SUO: WordNet Mappings




Also, of course, WordNet is being used more generally for
taxonomy/classification induction over document collections by emerging
software utilizing (generally non-symbolic) NLP technology. Some of
these systems are quite useful, but their value correlates with the
value of the underlying knowledge resources employed (such as WordNet or
ontologies).
