Automatically Labeling Semantic Classes
Patrick Pantel, Deepak Ravichandran · North American Chapter of the Association for Computational Linguistics · 2004
Systems that automatically discover semantic classes have emerged in part to address the limitations of broad-coverage lexical resources such as WordNet and Cyc. The current state of the art discovers many semantic classes but fails to label their concepts. We propose an algorithm labeling semantic classes and for leveraging them to extract is-a relationships using a top-down approach.
