Slide Presentation of the 2007 Annual Meeting of AHRQ

Lightweight Terminology

• Infrastructure includes interfaces to
  • NCI caBIG EVS
  • UMLS through JDBC and Relational Database
  • Hooks for Common Terminology Service (CTS)
• But we don't seem to need them
  • Knowledge master files and (trusted) data sources contribute codes, terms and synonyms.
  • We periodically run our word-indexer
    • To index words, phrases and codes
    • Context sensitive, i.e., by field
      • In case of observation value by observation code
  • User enters text (any of the synonyms),
    • Auto-completion maps to concept in the background
    • Unrecognized term stored as original text
