摘要
选取医学领域中具有代表性的心血管疾病作为知识工程的研究对象,以本体论作为指导理论,针对心血管概念体系研究了语义相关度计算方法,该方法可以定量地分析资源描述框架语言中的概念、特性之间的相关度,并便于进行本体的语义查询中的概念集扩充和查询结果排序.
The cardiology disease in medical domain is chosen as the representative research object of the knowledge engineering. Using ontology as the guiding theory, the computation method for the semantic correlation is studied in the conceptual hierarchy of cardiology disease. Such method can be used to analyze the correlation between concepts and attributes quantitatively, which is described by RDF. The groundwork of expansion of conceptual set and taxis of querying result for semantic search based on ontology is proceeded.
