基于本体的CAPP知识库管理系统研究

Study of CAPP Knowledge Base Management System Based on Ontology

为了合理有效地利用工艺知识,本文研究了工艺知识的获取和分类,提出了一个基于本体的工艺知识表示模型,将本体作为具体知识表示的元知识,与此同时,给出了一个基于本体的知识库框架结构,讨论了基于本体的知识检索和工艺知识库的维护,最后给出实例进行了验证。

To utilize process knowledge reasonably and effectively, we study its acquisition and classification and then propose a process knowledge representation model based on ontology, which is regarded as the meta-knowledge of specific knowledge representation. Meanwhile, we present an ontology-based knowledge base framework and disscuss the knowledge retrieval based on ontology and the process knowledge base maintenance. Finally, we present an instance to verify the process knowledge management.
