Query expansion improves retrieval effectiveness for MEDLINE citations. Using MetaMap for concept association is a viable alternative to retrieval feedback, with combined methods offering optimal results.

Area of Science:

  • Information Retrieval
  • Medical Informatics
  • Natural Language Processing

Background:

  • Statistically-based systems require effective query expansion for MEDLINE citation retrieval.
  • Retrieval feedback is a known method for enhancing user queries.

Purpose of the Study:

  • To evaluate MetaMap as an alternative query expansion technique.
  • To compare MetaMap-based query expansion with retrieval feedback.
  • To determine the optimal query expansion strategy for MEDLINE retrieval.

Main Methods:

  • Utilizing the MetaMap program to associate UMLS Metathesaurus concepts with user queries.
  • Conducting experiments to compare MetaMap-based expansion against retrieval feedback.
  • Analyzing retrieval effectiveness based on different query expansion strategies.
