摘要
知识库是基于语义的信息检索进行推理和知识积累的基础和关键,而本体Ontology则是知识库的基础。对基于本体的领域知识库架构及知识推理系统进行了分析研究,以高中生物学知识库的构建为应用背景阐述了领域本体概念树的抽取过程,并应用建模工具Protégé构建了OWL语言描述的生物学领域知识库实例,为下一步实现知识推理完成了知识表示。
The basis and key of knowledge accumulation and reasoning for information retrieval based on semantics is knowledge base. Firsdy this paper researched and analyzed domain knowledge base and knowledge reasoning system based on ontology. Secondly it elaborated the extraction process of concept tree of domain ontology by building the knowledge based on the knowledge of senior high school biology. Thirdly it built a biology domain knowledge base of OWL by using Protege, acquiring knowledge expressing which will be the next step for knowledge reasoning.
