Area of Science:

  • Medical Informatics
  • Natural Language Processing

Background:

  • Surgical procedure descriptions contain valuable clinical knowledge.
  • Extracting this knowledge automatically is challenging due to linguistic variability.

Purpose of the Study:

  • To upgrade the MultiTALE syntactic-semantic tagger for knowledge extraction from surgical procedure expressions.
  • To evaluate the performance of the upgraded tagger on a sample of surgical expressions.

Main Methods:

  • The MultiTALE tagger was enhanced for analyzing natural language surgical procedure expressions.
  • A random sample of surgical expressions was used for evaluation.

Main Results:

  • The upgraded MultiTALE tagger achieved 81% accuracy in analyzing the selected surgical expressions.
