Developers Are People, Too Presentation Transcript

  • 1. Developers are People, Too Mor Naaman Yahoo! Research Berkeley *Any views or opinions expressed during this panel are those of the author only and do not represent those of Yahoo, Yahoo! Research, or Flickr -- sometimes they do not even represent the author himself.
  • 2. People are Strange People are Strange. http://flickr.com/photos/genial23/334807527
  • 3. Why do People Tag?
    • Well, mostly, they don’t
    • But if they do (say, on Flickr):
    “ Why We Tag”, CHI2007
  • 4. Explanation, please
    • Simple
      • Source: Rashmi Sinha
    • Powerful
    • Tied with their natural motivations
  • 5. Our Mission
    • Automatically generate tag semantics
    • Few places to start
      • Word-based models
        • E.g., Flickr Clustering
        • E.g., Subsumption
        • E.g., LSI
    • Metadata can help, too
  • 6. tagmaps.research.yahoo.com “ World Explorer”, JCDL2007
  • 7. Extracting Event/Place Semantics “ Extracting Tag Semantics”, SIGIR2007
  • 8. Developers are people, too! http://flickr.com/photos/fotex/217896072/
  • 9. Developer Needs
    • Requirements for developing applications that make use or manipulate metadata:
    • Simple
    • Powerful
    • Tied with their natural motivations
    Just like people!
  • 10. I too am a Web2.0 Developer
    • My team will support a format:
      • If it’s simple
      • If it’s useful for us
      • If it “plays nice” with key applications
    • So far:
      • RSS and GEO-RSS
      • KML and GPX
      • EXIF (read only)
      • Flickr Machine Tags
  • 11. Machine Tags??
    • “ Machine tags are not RDF but they could play RDF on TV.”

  • 12. What’s the Point?
    • Format is emerging
      • Reflects needs of developers
      • Reflects properties of data
    • Simple
    • Powerful
  • 13. What’s the Problem?
    • Namespace/semantics not defined
      • Multiple formats for same semantics
      • Multiple semantics for same subjects/predicates/objects…
    • It’s up to us to make sense of it
      • Us == researchers
    • Schema mapping, pattern extraction and recognition, semantic analysis…
  • 14. Discuss: The Semantic Web is Dead Welcome to the Emerging-Semantics Web!
  • 15. Send me your wrath More fun and games: www.yahooresearchberkeley.com Mor Naaman http://infolab.stanford.edu/~mor
