  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. Skeptical reactions Practical feasibility An unrealized idea Censorship and privacy Doubling output formats Need so much religion, so little time 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 toinformation seeking than google

  9. what would google do? PageRank tf-idf SYSTEM: rank using IR model USER: information Need query select from results

  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!
