Finding Parts in Very Large Corpora

Matthew Berland, and Eugene Charniak

January 1999


We present a method for extracting parts of objects from wholes (e.g. ``speedometer'' from ``car''). Given a very large corpus our method finds part words with 55%\ accuracy for the top 50 words as ranked by the system. The part list could be scanned by an end-user and added to an existing ontology (such as WordNet), or used as a part of a rough semantic lexicon.
