Integration of Japanese Medical Device Adverse Event Terminologies.

The purpose of this study is to integrate Japanese medical device adverse event terminologies for evaluating terminological consistency. We represented hierarchy and relations among terms using Resource Description Framework (RDF). There were 3521 classes and 14650 properties. As a result of evaluating the consistency of the description in SPARQL, it was evident that the same notations existed within different terminologies (category terms and terms) and some terms had plural definitions.
