The proliferation of Web-based information services, heterogeneous
information content and resources, and ubiquitous Internet access have
brought great challenges to integration and search of information. Dr. Lee
is developing architectures, algorithms and tools that facilitate efficient
retrieval, integration, search, analysis, mining, and visualization of
information from disparate and large information sources. He is particularly
interested Information related to, while not limited to, space and time. He
is also involved in re-architecting and implementing the next generation
CiteSeer (http://citeseer.ist.psu.edu/) in order to tackle the scalability
and other critical performance and research issues. One primary design goal
of this new architecture is to provide more flexible and versatile web
services for specialized information search and system integration on the
Internet. Finally, the Internet information services will eventually be
mobilized and personalized such that the users may access to information
without geographical limits. He is looking into technologies for supporting
various services, including multimedia (such as voice, data, text, video
streaming) for mobile users.
Research in this direction is supported in part by a grant from ARDA (the
advanced research and development activities) which is a joint Department of
Defense/Intelligence Community organization.
