基于本体化知识模型的知识库构建模式研究

Design Pattern of Knowledge Base Based on Ontology Knowledge Model

在研究了知识模型及知识库相关理论和技术的基础上,结合本体论,提出了一种基于本体的知识模型,并从领域知识、推理/方法知识和任务知识三个角度给出了本体化知识模型基于BNF范式的表达式;基于所建立的本体化知识模型,在对知识进行可拓性分析的基础上,提出了一种知识库结构模式,对于知识模型与知识库的匹配问题进行了讨论,并在理论研究的基础上,给出了利用SQLServer数据库系统建立的知识库示例。

On the basic of the research about knowledge model and knowledge base,a kind of knowledge model based on the ontology theory is set up.Also,the knowledge model is defined by three knowledge categories of domain knowledge model,reason/means knowledge model and task knowledge model.These categories are the set which made up of knowledge atom and knowledge entity.According to the knowledge model,a design pattern of knowledge base is put forward,which discusses the match mechanism about the model and knowledge base.At last,a sample of knowledge base based on data Base is realized.
