新的面向对象知识表示方法

New object-oriented knowledge representation method

针对传统知识表示方法缺乏过程性知识表示能力、不具备动态特征、难以表示装备保障领域知识的问题,在借鉴框架表示法、语义网络表示法的基础上,结合面向对象思想,提出了一种新的知识表示方法——动态对象网络(DON)。DON表示法以类来表示概念,将知识表示为概念以及概念间的关系。给出了概念的详细结构及其演化机制,关系的描述方式,并将守护方法思想引入概念中,在此基础上探讨了DON中的推理机制,为灵活、动态表示装备保障领域知识,实现装备保障信息的共享和融合提供了基础。

Aiming at the limitations of traditional knowledge representation, such as lack of ability to represent processing knowledge, short of dynamic characteristics and difficulty to represent knowledge in domain of equipment support, a new object-oriented knowledge representation method called Dynamic Object Network （DON） was proposed, which combined object-oriented technology with the frame and the semantic network. Dynamic object network represent concept with class, considering knowledge as concepts and relationships between the concepts. This paper proposed detailed structure of concept and its evolution, representation of the relationship and introduced watch method to the concept structure, and then discussed the reasoning of the dynamic object networks. The dynamic object network offer a base for represent knowledge in domain of equipment support and realization of information-sharing and information fusion.
