Design And Implementation Of Medical Information Retrieval System Based On Semantic Analysis

With the rapid development of the Internet,medical information is increasingly rich,more and more ordinary users and health care related personnel tend to use the Internet to obtain the appropriate medical information.In view of the frequent updating of Internet information,the user needs more and more accurate search results,the general retrieval technology has been unable to meet the requirements of users,so the semantic analysis of information retrieval technology has become a new research hotspot,will gradually become a lot of areas Useful tool.It is a kind of more powerful retrieval technology which combines traditional information retrieval technology and artificial intelligence technology.It analyzes the retrieval request from the perspective of semantic understanding,and matches from the retrieval of concept and its relation.The current situation is that the usual search engine for medical information is not done specifically to deal with,resulting in keyword-based medical professional search retrieval quality and efficiency are not high.The main reason is that there is no annotation of the document-related semantics,nor the user's request for semantic analysis in advance,but simply the user's request made at the character level to match the mechanical.Therefore,the in-depth research and exploration of medical information retrieval technology based on semantic analysis has become a hot research topic in this field.The main content of this paper is to study the medical ontology construction of the medical information retrieval system of the medical ontology and the semantic processing of the users based on the medical ontology,and design a medical information based on semantic analysis Retrieval system-Medica1 Search,from the system used by the relevant technology,detailed requirements and implementation principles and other aspects of a detailed description,and design,implementation and testing.
