James Pustejovsky (born 1956)[1] is an American computer scientist. He is the TJX Feldberg professor of computer science at Brandeis University in Waltham, Massachusetts, United States. His expertise includes theoretical and computational modeling of language, specifically: Computational linguistics, Lexical semantics, Knowledge representation, temporal and spatial reasoning and Extraction. His main topics of research are Natural language processing generally, and in particular, the computational analysis of linguistic meaning. He holds a B.S. from MIT as well as a PhD from the University of Massachusetts, Amherst.
Pustejovsky first proposed generative lexicon theory in lexical semantics in an article published in 1991,[2] which was further developed in his 1995 book of the same name. His other interests include temporal reasoning, event semantics, spatial language, language annotation, computational linguistics, and machine learning.
