exploring semantic means

Daniel Tunkelang, Chief Scientist of Endeca

Endeca is a leading provider of enterprise information access. While Endeca is not a “semantic web” company (we’re more of an XML / XQuery shop), we share Tim Berners-Lee’s dream of exposing the semantic content of data to reduce the tedious and brittles processes that people use today in order to meet their information needs, whether on the web or in the enterprise. Our emphasis is on exploratory search, as contrasted with the “10 blue links” approach that characterizes conventional search engines. Come join us for a tour of how we are enabling a conversation between humans and data through content enrichment and set-oriented retrieval and analysis.

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
