IEEE CIS Montreal Chapter Seminar Announcement

Title: WordSpace as a technique for text data-mining By: Dr. Lorne Bouchard

  Date and time: April 1, 2010 at 10:30

Where: UQAM, President-Kennedy building, # PK-4610 201, President-Kennedy Ave (Metro Place-des-Arts)

This seminar is organized in conjunction with DIC (Doctorat en Informatique Cognitive) at UQAM. The presentation will be in French

Mounir Boukadoum, Ph.D., SMIEEE CIS Montreal Chapter Chair

Abstract

WordSpace is a data mining technique that can be used to elucidate meaning in textual information. As with earlier work on information retrieval, WordSpace is based upon a geometric model of high dimensionality, the dimensionality of the space being subsequently reduced in order to extract the sought results. Random indexing, based upon the work of Kanerva and Plate on the representation of symbolic data in neuronal nets, avoids the dimension reduction step by directly constructing a reduced dimensional space. The talk will illustrate the technique with examples taken from the literature and will show how to easily deploy it using the many open source programs that are available.

Presenter’s Short Biography

Dr Lorne Bouchard received the B.A. (Mathematics-Physics) magna cum laude frorm College Sainte-Marie, Montreal, in 1960, the B.Sc.A. (Engineering Physics) magna cum laude from Ecole Polytechnique, Montreal, in 1964, the M.Sc. (Computer Science) from University of Manchester, Manchester (UK), in 1966, and the Ph.D. (Mathematics) from Boston University, Boston (USA), in 1979. He joined UQAM in 1970 and is of the pioneers behind its current Computer Science programs. After holding various academic positions as teacher and program manager, both at the national and international level, he “retired” in 2006 only to come back as adjunct professor and continue his activities with undiminished energy. His current research interests are in the areas of knowledge engineering and natural language processing, with application to web information spotting.
