摘要: 提出了一种基于本体论实现产品全过程知识共享的方法。对产品知识进行了层次化的表示,并借助 ODLBKIF和基于角度知识描述语言进行了说明。同时,给出了基于本体论的知识推理方法。借助角度知识,对领域知识进行描述,且给出知识的通信机制,设计了基于本体论的应用系统共享产品全过程知识的体系结构。最后,通过实例模型提供了研究成果在实际建模系统中的应用。

Abstract: A method to realize knowledge sharing in the whole process of product based on ontology is proposed. The hierarchical denotation of product knowledge is demonstrated by means of ODLBKIF and the described language based on aspect knowledge. Furthermore, in virtue of aspect knowledge, the domain knowledge reasoning method and the communication mechanism is explained and the sharing knowledge architecture of product process is built. Finally, a valid example is presented to demonstrate the validity and practicability of the study.

Key words: Aspect knowledge, KIF, Knowledge sharing, Ontology, DCS, information fusion, relative entropy, degradation feature extraction
