Research On Medical Domain Ontology Building Based On Thesaurus

Popular in Internet era, information on the web showed a mass rapid growth, how can the information sea to find the information they need, and not an easy thing. Based on the above problems, some people put forward the conception of Internet into semantic net, the semantic web as the future direction of development. In view of its implementation, the experts proposed the introduction of ontology in semantic web. The ontology can solve the semantic retrieval of the core issues, can make the body image as a" semantic bridge", the bridge end is formal grammatical description, the other end is an abstract concept model.The main content of this paper includes the following sections:First, introduces the research background, this article put forward the research goal and the significance, the present research situation at home and abroad is analyzed, finally the technology roadmap. Related basic theory, introduce the basic concept of ontology, types, modeling primitives, and comparative analysis of the various existing ontology building tools.Secondly, taking mesh as the primary medical domain ontology construction process, elaborates the construction rules, proposed four-dimensional general medical ontology model and the improvement, expounds the mesh table for the basic construction of medical domain ontology design steps, finally elaborated disease ontology retrieval function.Finally, constructs the ontology domain ontology evaluation related to, in the aspects of body excellent or not made comprehensive review. Then the article carries on the summary, and put forward to future work expectations.The main train of thought is the medical subject headings for the foundation, based in Jilin province hospital work experience, combined with the author's information management learning experiences, information retrieval and classification of diseases combined, using medical subject headings, constructing multidimensional to coronary heart disease associated with a breakdown of disease of disease based on ontology model, focuses on the study of in this disease coronary heart disease arrhythmia breakdown, research on the disease more single-minded, so the application is relatively accurate, the diseases under the two category breakdown of retrieval is more efficient.Production method of combining western scholars proposed by Hadzic et al, four-dimensional general disease ontology model, the model is improved, proposed inclusion six dimension model, by the ontology constructing method frequently used in the seven step and prot e g e tool, first time in China the medical field heart disease arrhythmia ontology construction test. Through the establishment of concepts, concept between inherited, constraint, examples of relationship between the expression of cardiac arrhythmia domain knowledge, finally try to realize a portion of the body retrieval function.
