Integrating Terminologies and Services using Semantic Web Standards

Abstract

Many healthcare terminology standards and classi cations such as ICD, SNOMED, CPT have emerged in last few years and are widely used in various healthcare applications to encode and represent patient records. However, almost all terminologies are represented using di erent data models and in- volve incompatible formats. For consistent understanding of patient records, terminologies should be represented using a canonical format. This thesis proposes a semantic model, build using HL7-CTS2 and SKOS to bridge the gap between the terminologies. The semantic model accommodates heteroge- neous medical terminologies as a federated terminology distribution service. A RESTful framework is also developed over the semantic model to pro- cess the terminological contents for a proof of concept. The service allows browsing and navigation for searching terminology contents in an integrated platform. Moreover, the proposed system is expected to enhance the seman- tic interoperability beyond the traditional health care applications.
