  2. For Today . . . • Landscape of Search in 2008 • Update on Established Services • New Services • Creating Custom Search Engines

  3. Why do I need more than Google? • The Google effect -- • the single most powerful force in today’s Internet • a private profit-driven company • owns more information on individuals’ search behavior, companies and organizations than any other entity

  4. Why do I need more than Google? • Great potential for misuse/abuse of this information for financial gain • Societies seldom leave basic services (utilities, medical and traffic regulation) totally to the “free market” • Is web search now a “basic service” ???

  5. Search dominance --- • Potential skewing for commercial, political or social purposes • Database composition • Ranking • Privacy • No single search engine can crawl the whole web • Limits search features, results display, consumer and shopping information • http://google-watch.org

  37. Linked CSE • Sites can be added “in bulk” • Select among your sites for individual queries through specification files • Requires user to host and maintain their own XML specification files • Migration from stored to linked versions possible • More difficult to add single sites • Use G’s Search API’s to integrate other Google services into a CSE

  40. Semantic Search Systems • Expensive and time-consuming for general web search; more possible in subject-specific contexts “What is palladium used for?” • Link-based crawler results: London’s Palladium Theatre • Include the concept map “used for” Sites about the element palladium • Hakia, Powerset, Cognition Search

  41. Post SearchWhat do we do AFTER a search? • The search engine size wars are over • WANTED: Services that help manage, share and update • Web search results • Tagged sites WITH scalability confidentiality “collaborability” across all platforms, devices and file formats
