My research interests are:
- Enhancing Web information access through Web retrieval,
Web page classification, Web user analysis, and so on;
- Full text database retrieval technique; etc.
I am also interested in research and development of scholarly
information service systems such as an electronic journal and
a scholarly article navigator.
