An evaluation of medical knowledge contained in Wikipedia and its use in the LOINC database describes a system that uses Wikipedia information for part of LOINC information.

The rearchers describe a Java software tool, Wikipedia to LOINC matcher (WLMA), for mapping Wikipedia articles with LOINC parts.

The tool has a number of components:

  1. Handling of Wikipedia disambiguiation pages
  2. Re-querying
  3. Examination of article category
  4. Use of Unified Medical Language System to find the semantic type of LOINC parts
  5. Extraction of the introduction sectio of Wikipedia articles
  6. Exclusion of LOINC parts with "derivatives", such as "AB", "AG", "RNA" and "IgM"

[edit] Data

  • 1705 LOINC parts were used for the matching

[edit] Results

  • 1416 matches, 289 no matching
  • 1299 complete matches (true positive), 15 partial matches and 102 non-matches
  • 15 of the 289 no matching was found to match Wikipedia articles with manual query (false negative)

That is, 1299 +15 +15 = 1329 out of 1705.

The description from Wikipedia was made part of LOINC.
