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.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
