Title: Information Retrieval and Databases: Synergies and Syntheses


1
Information Retrieval and Databases Synergies
and Syntheses
  • Peter Clark
  • Mathematics and Computing Technology
  • Boeing Phantom Works
  • The Boeing Company

2
Information Retrieval and Databases Synergies
and Syntheses
  • Boeing faces huge challenges with mixed data
  • parts, dimensions, locations, costs, schedules,
  • procedures, functions, protocols, design
    principles,
  • Documentation for a 747
  • would not fit inside the aircraft
  • even if it could, the aircraft would be too heavy
    to fly
  • (and, every 747 is different!)

Key Challenges in Integrating IR and DB Approaches
Premise
  • Synergy requires explicit, shared semantics

Structure chasm ? Semantics chasm?
Challenges
  • Extracting the semantics of unstructured data
  • Encoding the semantics of structured data
  • Defining useful, shared ontologies
  • Machine inference
  • Leveraging common-sense knowledge

4
Integrating IR and DB approaches Two Snapshots
within Boeing
  • ESDS
  • An expert system for standards knowledge
  • ? deductive database canned text paragraphs
  • Synthesizes custom page on the fly
  • Resource Locator
  • Texts tagged with concepts (from a Thesaurus)
  • Retrieval based on semantic distance
