Title:  What does relevance mean for health information on the Web?

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.
