Bullet 1: Semantic Heterogeneity

  • Achilles heel of data warehouse projects
      • And information integration
      • And soon of web services
  • Easy part is euros to/from dollars
      • Harder is French salary to/from U.S. salary
      • Hardest is latex gloves to/from rubber hand protectors
slide3

Bullet 1: Semantic Heterogeneity

  • Worked on ever since I have been an adult
      • With little progress
  • At some point we need to work on the important stuff…..
slide4

Bullet 2: Google for Structured Data

  • What is the current temperature in Lowell?
  • Is Flight 214 on time?
  • Where can I buy pocket protectors?
slide5

Bullet 2: Google for Structured Data

  • Data model
      • Not likely to be text
  • Query language
      • NL doesn’t work (and won’t anytime soon)
  • Integration of 10** 6 sites
      • Semantic heterogeneity……
      • Site finding --UDDI is a start
      • Scalability -- 10**6 gateways?
