in Chinese language corpora, espcially in his role in developing the LIVAC project. Professor Benjamin K. Tsou received his secondary education in Singapore and obtained his doctorate in Linguistics from University of California, Berkeley. He was the founding Pro-Vice-Chancellor of the City University of Hong Kong, and is currently Director of Language Information Sciences Research Center and Chair Professor of Linguistics and Asian Languages at the City University of Hong Kong. His research interests focus on Sociolinguistics and Corpus Linguistics. He spearheaded the LIVAC Synchronous Corpus in 1994, which to-date, contains over 400,000 marked lexicons from representative Chinese newspapers and electronic media of Hong Kong, Taiwan, Beijing, Shanghai, Macau and Singapore. This is by far the largest Chinese corpus with the widest coverage. The LIVAC (Linguistic Variations in Chinese Speech Communities) synchronous corpus, http://www.livac.org/ pioneered by the Language Information Sciences Research Centre at The City University of Hong Kong, contains texts from representative Chinese newspapers and electronic media of Hong Kong, Taiwan, Beijing, Shanghai, Macau and Singapore. The collection of materials from the diverse communities is synchronized, and so offers an innovative "Window" approach for a whole variety of comparative studies and useful IT applications.
