ABSTRACT
Natural language processing systems are increasingly integrating lexicons with ontologies for word sense disambiguation (WSD). Manually acquiring a lexicon that is integrated with a large ontology and other semantic resources can be difficult and inefficient in part due to the complexity of ontologies and inconsistency of entity extractors supporting WSD applications. A major contributing factor to the difficulty is the creation of selectional restrictions with respect to particular semantic resources. This paper presents a process for acquiring complex expressions for selectional restrictions via search through an ontology.
