在充分复用丰富的医学知识组织体系基础上,构建以UMLS为主导的多本体融合的医学数字资源语义互联模式,即一种基于全局本体统控、多种本体融通的模式框架。以UMLS为主导的多本体融合模式由三个基本层和两个链接层构筑。从UMLS本体的全局统控、多本体融合的语义标引机制、多本体融合的语义检索模式、多本体融合的信息集成构架这4个方面详细阐述医学数字资源语义互联的机理。从自然语言处理、智能检索、本体学习、知识发现和专业知识聚类等方面分析医学数字资源语义互联的功能。
On the basis of fully reusing a rich medical knowledge organization system, a multi-ontology-based multi-ontology medical digital resource semantic interconnection model based on UMLS is constructed, namely a model framework based on global ontology control and multiple ontology facilities. The multi-ontology fusion model dominated by UMLS consists of three basic layers and two link layers. This paper elaborates the mechanism of semantic interconnection of medical digital resources in detail from four aspects: global control of UMLS ontology, semantic indexing mechanism of multi-ontology fusion, semantic retrieval mode of multi-ontology fusion and information integration framework of multi-ontology fusion. From the natural language processing, intelligent retrieval, ontology learning, knowledge discovery and professional knowledge clustering and other aspects of the medical digital resources semantic interoperability.
