  1. Intent Mining from Search Results Jan Pedersen

  2. Outline • Intro to Web Search • Free text queries • Architecture • Why it works • Result Set Mining • Disambiguation • Correction • Amplification

  3. The Worst Interface (ca 1990) The Search Interface (ca 2010)

  4. Search wasn’t always like this ttl/(tennis and (racquet or racket))isd/1/8/2002 and motorcyclein/newmar-julie Source: USPTO

  5. Salton’s Contribution • Free text queries • Approximate matching • Relevance ranking • Exploit redundancy • Meta data • Scored-OR Source: cs.cornell.edu

  6. Life of a query Gerry Salton (Scored-OR 10, ([(“Gerry” or “Gerald”),0.3], [“Salton”,0.7])) Index • Separation between user query and backend query • Relevance scoring and ranking • Query-in-context summaries

  7. Why Does it Work?

  8. Semantic Meta-Data

  9. Result Set Mining

  10. Query Expansion • [Gerry Salton]  [Gerry Salton Cornell] • Disambiguation via Expansion • Pseudo Relevance Feedback (Evans)

  11. Life of a query (2) Gerry Salton (Scored-OR 10, ([(“Gerry” or “Gerald”),0.3], [“Salton”,0.7])) Gerry Salton  Gerry Salton Cornell Index • Result Set Analysis • Automated Query expansion • Reranking

  12. Spelling Correction Scored-AND(200, OR(“britinay”, “britney”), OR(“spares”, “spears”)) Blend(Scored-AND(200, “britinay”, “spares”), Scored-AND(200, “britney”, “spears”)) • Session Log Mining • Multiple queries with Blending • Behavioral feedback loop

  13. Web Search Gerry Salton • Speller • Synonyms Third Stage reRanking: 50 (Scored-AND 200,”Gerry”, “Salton”) Second Stage reRanking: 5K First Stage reRanking: 100K News Index Local Index Index Index Index Index 100B • Query Understanding • Federation • ReRanking and Blending

  14. Entity Detection • Grouping • Summarization

  15. Post Result Triggering • Alternative to Answer Blending • Structured Data integration • Off-page data joins

  16. Grouping • Reranked Results • Compressed Presentation • Coherently grouped

  17. Summary • Web Queries are not User Intent • Suffer from ambiguity and errors • Intent can be mined from results • Query Correction • Disambiguation • Grouping and Organization
