Description

eorges Dupret graduated as a civil engineer in Applied Mathematics from the University of Louvain, Belgium. He obtained his PhD from the University of Tsukuba, Japan for his work on spatial data forecasting based on Artificial Neural Network. At the same time, he worked for the IBM TRL Research Laboratory in the field of Information Retrieval for the automatic identification of relevant topics and issues in a call center transaction data. This involved the efficient approximation of Singular Value Decomposition of sparse, huge matrices. He continued this work in the IBM Research Laboratory in Z├╝rich, Switzerland and extended it to Quality Insurance transactions. After two years as a researcher in the Center for Web Research in Santiago, Chile, he is now working for Yahoo! Research Latin America. Topics of interest are web mining, clickthrough data analysis and modelization, query disambiguation and recommendation and automatic taxonomy construction.
