Dr. Jean Mark Gawron (Co-PI)
Ph.D., University of California at Berkely
Department of Computational Linguistics, SDSU

Dr. Jean Mark Gawron is a computational linguist with 30 years of experience in the field. His areas of research have been logic, logical semantics, parsing, and lexical semantics. In this project he is using dependency parsed data to createdistribution vectors for all words and experimenting with Lin’s sim measure (Lin 1998), cosine, and Latent semantic indexing (Deerwester 1990) as measures of similary between words, which in turn will help build thesauri and ontologies. He is also experimenting with using a cluster of factors involving _citation_analysis_ as a component of the web page classification model. Citation analysis is the study of patterns of reference by authors to other authors and texts. As a field it predates the web (Garfield 55 Pinski and Narin 1976);
