Exploiting Domain Thesaurus for Medical Record Retrieval

Abstract

InfoLab at the University of Delaware participated in the TREC 2012 Medical Records Track. This paper explains our method and describes experiment results. One limitation of existing keyword matching based retrieval functions is the problem of vocabulary mismatch. To overcome this limitation, we propose to first map topics and visits to bags of concepts using domain thesaurus, and then model the relevance based on the similarities between those concepts.
