Due to the lack of a uniform schema for Web documents and the sheer
amount and dynamics of Web data, both the effectiveness and the efficiency
of information management and retrieval of Web data is often unsatisfactory
when using conventional data management and searching techniques.
To address this issue, we adopted a web mining and web community analysis
based approach, where web community is defined as a set of closely related
Web-based documents/objects. Based on the analysis of Web document
contents, hyperlinks and/or user access logs, we have developed various
approaches or algorithms to construct and analyze Web communities, and
then to make recommendations / personalization.
The first part of this talk will discuss web community analysis and construction.
The second part of the talk will introduce some e-research projects related
to e-health, e-Water and e-Law/legal information management, and discuss
the experience on these cross domain research collaborations.
