My current research interests are knowledge discovery from large databases and information retrieval. In particular, I am interested in data mining from the Internet and data mining from multimedia repositories. The research work I am conducting focuses on web mining related to the content of web documents, the structure of the hypertext documents, and the usage of the World Wide Web.
My research on Web Mining includes: (1) Meta Web, an architecture for abstracting web content and structure and facilitating resource discovery and implicit knowledge extraction; (2) WebML, a declarative query language for web mining; (3) Web access log mining for user browsing behaviour understanding and adaptive web site construction; (4) Analysis of web usage for e-commerce and automatic on-line catalogues.
I am also interested in Content-based Image Retrieval and visual asset management. My recent research has focused on pattern discovery from multimedia repositories such as image and video collections. The application of these techniques for medical imaging is of particular interest to me.
Another research interest is data visualization and manipulation for large data collections or for data mining and analysis results.
