ITS系统中知识模型的设计与实现

On the Design & Implementation of Knowledge Model in ITS System

ITS系统中,知识表示是一个关键问题。如何表示好知识关系,构建领域知识模型,难度很大。本文讨论了ITS系统中知识点间关系的表示,特别对于知识点间依赖关系的设计与表示,提出了一个知识图模型,结合了树和有向图的表现形式,并给出了一些构建原则,能够较好解决当前知识表示中存在的不足。最后用相应的关系数据模型给予实现。

The knowledge representation is a key problem in ITS system. It is difficult to express the good knowledg.e relation and construct a field knowledge model. This paper discusses the representation of the relation between deferent knowledge in ITS system, especially the design and representation of dependence relation, and puts forward a model integrating the tree and direction graphs and some constructing principles. This model earl solve the problems existing in the knowledge representation. Finally it implements the model by using the related data.
