A New Electronic Medical Record Retrieval System Based on Ontology and Mapping Algorithm

摘要

Information technology and medical technology have developed rapidly, making evidence based medicine has become an inevitable trend of electronic medical record. However, as non-standard of the medical concept of the lack of unified nomenclature system norms, leading to a concept can be expressed by a variety of names. And traditional searching methods can not be semantic query expansion, recalls rate and precision rate is not high. In this paper, ontology was introduced in the electronic medical record, and we also present a mapping algorithm and similarity algorithm to achieve expansion of the semantic of concept, to improve the recall rate and precision.
