Building of the Predicate Recognition System for the NLP Ontology Learning Module.

The practical approach to recognizing a description logic predicate in a natural language sentence is presented. The approach is based on using the open source tool - Link Grammar Parser in combination with Protégé-OWL API. Machine learning method of recognition based on naïve Bayes allows distinguishing kind of previously learned binary predicate and roles of its attributes. The predicate recognition system had been included into ontology learning module of the CROCUS application.
