广义KRA抽象模型

General KRA Abstraction Model

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Oa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.

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.
