ABSTRACT:
Information retrieval researchers have paid more attention to topical relevance rather than information quality. However, health information of bad quality could lead to personal endangerment, especially since health information is so widespread on the Internet. Users of search engines should be provided with search services that return high quality results, eliminating web pages with low quality information from the result list.

This talk will mainly introduce an approach for building a health portal search for that purpose. Other topics covered in the talk include a comparison of the performance between domain-specific and general-purpose search engines; and an automatic tool to evaluate the quality of medical web sites.
