Outline of Final Research Achievements

This study aimed to develop a clinical information retrieval system that utilize life-science knowledge resources for query expansion. We developed a generic method to convert HL7 version 2.5 messages into the RDF, and also converted five kinds of existing drug databases into RDF and provided explicit links between the corresponding items among them. With those linked drug data, we then developed a method for query expansion to search the RDF-ized HL7 v2.5 messages using semantic information on drug classes. An evaluation of the proposed method in use case for detecting adverse drug events showed that the execution time of the developed queries increased with the amount of clinical data without diverging.
