Mine What Web Search Engine Finds

• Current Web search engines: convenient source for mining

  • keyword-based, return too many answers, low quality answers, still missing a lot, not customized, etc.

• Data mining will help:

  • coverage: “Enlarge and then shrink,” using synonyms and conceptual hierarchies
  • better search primitives: user preferences/hints
  • linkage analysis: authoritative pages and clusters
  • Web-based languages: XML + WebSQL + WebML
  • customization: home page + Weblog + user profiles
