Towards Automatic Acquisition of Ontological Knowledge - 2004

Explore a comprehensive lecture on automatic acquisition of ontological knowledge presented by Dr. Patrick Pantel from the Information Sciences Institute at USC in 2004. Delve into semi-automatic methods for extracting fine-grained semantic relations between verbs, including similarity, strength, antonymy, enablement, and temporal happens-before relations. Learn about the VerbOcean resource and its creation using lexico-syntactic patterns over the Web. Discover current work on ontologizing lexical resources and the challenges of assigning and disambiguating grammatical templates to ontology nodes. Understand the potential benefits of this research, including improved unsupervised word sense disambiguation and the personalization of ontologies like WordNet to specific domains. Gain insights from Dr. Pantel's expertise in semi-automatic ontology construction, text mining, knowledge acquisition, and machine learning, developed through his distinguished academic career and research work at USC's Information Sciences Institute.
