I have been involved with and worked on a number of research projects in Web IR and bioinformatics areas for the past several years. For example, I worked on a project to develop an information retrieval system for the gene information. Text mining technologies were used to extract a number of essential keywords for some important genes. Based on these keywords, we built an indexing and searching system for a collection of gene information. Currently I am working on a peer-to-peer social information retrieval application called Sixearch.org (6S). The application was designed to address the scalability limitations of centralized search engines by providing a collaborative platform for searching and sharing Web documents among participating peers. In this project, an adaptive query routing algorithm was designed and integrated with a topical crawler and a search engine to provide an alternative search application. A new evaluation framework, instead of the traditional precision and recall approach, was also developed to assess the performance of peer networks. Papers: (plagiarism notice) 1. L.-S. Wu, F.
