Research interest:

My main research works are in computational linguistics. That is, using computational methods to process Chinese text, extract useful information, and build Chinese NLP related resources.  My expertise is in lexical semantics, text mining, opinion analysis, knowledge discovery. 

My other interest in on open systems development to address issues in support interoperability of computer systems, especially in encoding methods for Chinese language processing. I am still actively contributing to the technical development of open systems related standards.

My Teaching :

·         Courses taught: PolyU courses include COMP100(Introduction to IT), COMP212 /COMP2421 (computer Organization and Architecture), COMP323(Foundations of Chinese Computing), COMP417/(Data Warehousing and Data Mining), COMP567(outpost), COMP5132(Information System Acquisition and Integration), FH6051(Computational Linguistics, COMP 6402(Natural Language Processing Techniques), and COMP5512(Information Technology and Logistics).  I have experience teaching courses in Data Structures, Database Systems, Operating Systems, Distributed Systems, Programming Languages, etc.. Most of the teaching materials are now posted under Blackboard system.

·         Other activities: I have gone on to two service learning trips organized by my colleagues, , one in Gansu in 2008(organized by Stephen, Grace, and Vincent, and one in 2010 in Cambodia(organized by Stephen and Grace). My role is to lend a helping hand during the trip. It was a great opportunity to learn, to serve, and to help out.  I would encourage all students to join some service learning activities.
