摘要/Abstract

摘要： 针对KRA抽象模型的表示框架进行扩展, 将感知过程分解为初步感知过程和抽象感知过程两部分: 初步感知过程将该模型提供的一个框架R表示世界W在初步感知系统P的作用下映射为P(W), 该过程不改变W中具体对象的实体属性; 抽象感知过程将P(W)在感知系统P^*的作用下映射为P^*(W), P^*(W)中的对象称为抽象对象, 抽象对象的类型根据感知者预先定义的抽象对象库O_a的不同而不同. 这种建模过程的细化可生成W的不同抽象模型, 使推理得到简化.

Abstract: The authors extended the representing framework Rof the KRA model so as to divide the perception into primary perception and abstraction perception. In the process of primary perception,Wunder the primary perception system P is mapped as P(W) where the attributes of the objects in Wdo not change. In the process of abstraction perception, Wunder the abstraction perception system P^* is mapped as P^*(W). The objects in P^*(W)are abstraction objects, the types of which are related to the abstraction objects database predefined by the agent. The specified modeling process can generate various abstraction models of W, making the reasoning simplified.

Key words: abstraction model, general KRA abstraction model, pri mary perception, abstraction perception 
