exploring semantic means - Presentation Transcript

  1. exploring semantic means Daniel Tunkelang Chief Scientist, Endeca
  2. about me
    • 1988 – 1992
    • 1993 – 1998
    • 1999 -
  3. overview
    • a means, not an end
    • exploratory search (HCIR)
    • searching for meaning
  4. do you like our owl?
  5. a means, not an end The Semantic Web will improve the connections between knowledge on the web and software.
  6. so much religion, so little time
    • Skeptical reactions
    • Practical feasibility
    • An unrealized idea
    • Censorship and privacy
    • Doubling output formats
    • Need
    vs.
  7. what semantic means to (people who pay) me
    • using linguistic and statistical approaches to derive meaning from unstructured text
    • using semantic web approaches to represent meaning in content and query structure
  8. exploratory search
    • what i really care about
    • what you should care about too
    • especially if you see more to information seeking than google
  9. what would google do? information Need query select from results rank using IR model USER: SYSTEM: tf-idf PageRank
  10. assumptions of relevance-centric approach
    • self-awareness
    • self-expression
    • model knows best
    • answer is a document
    • one-shot query
  11. human-computer information retrieval
    • don’t just guess the user’s intent
      • optimize communication
    • increase user responsibility and control
      • require and reward human intellectual effort
    “ Toward Human-Computer Information Retrieval” Gary Marchionini
  12. let’s make this concrete
    • Colleague: Hey Daniel! You should check out what this guy Steve Pollitt’s been researching. Sounds right up your alley.
    • Daniel: Sure thing, I’ll look into it.
  13. google him!
  14. google scholar him?
  15. hcir-inspired interface
  16. tags provide summarization and guidance
  17. my information need evolves as i learn
  18. how did we do that?
    • wisdom of crowds
    • corpus analysis
    • scope the problem
    • target exploratory search
  19. if you prefer sports to computer science
  20. a more current slide…
  21. hcir can get fancy
  22. and there’s query structure side of semantics
  23. a more current example All reviewers Reviewers Under 18
  24. one last example
    • “…As an example, I may be interested in the tensions between government and newly nationalized banks over the bonus culture that taxpayers are now funding (a hot topic in the UK currently)…”
    • --a commenter at The Noisy Channel, in a discussion of exploratory search for news
  25. still in private beta…
  26. following the information scent
  27. to explore the news
  28. in closing
    • let’s not quibble over protocols
    • exploration is the killer app for semantic tech
    • it’s real, and it’s fabulous!
  29. thank you
