Towards semantic search and inference in electronic medical records : an approach using concept-based information retrieval
Koopman, Bevan, Bruza, Peter, Sitbon, Laurianne, & Lawley, Michael J. (2012) Towards semantic search and inference in electronic medical records : an approach using concept-based information retrieval. Australasian Medical Journal, 5(9), pp. 482-488.
This paper presents a novel approach to searching electronic medical records that is based on concept matching rather than keyword matching.
The concept-based approach is intended to overcome specific challenges we identified in searching medical records.
Queries and documents were transformed from their term-based originals into medical concepts as defined by the SNOMED-CT ontology.
Evaluation on a real-world collection of medical records showed our concept-based approach outperformed a keyword baseline by 25% in Mean Average Precision.
The concept-based approach provides a framework for further development of inference based search systems for dealing with medical data.
