扩展的G-KRA抽象模型

将广义知识重构与抽象模型框架下的初步感知过程扩展为多重感知过程, 根据物理世界W中对象所属域的不同生成多重域抽象模型, 并讨论了两种情况下域抽象模型Wi和Wj间的域关系： W的多重域模型W_i和W_j中的构成对象交集为空（即W_i和W_j中不存在有跨域行为的实体）； W的多重域模型W_i和W_j中的对象实体存在跨域行为. 扩展后的框架R丰富了物理世界W的模型表示, 使对象感知由平面感知变为立体感知, 应用多种领域知识生成相互关联的不同域模型, 增强了模型的推理能力.

Extended G-KRA Abstraction Model

The primary perception process of the generalized knowledge reformulation and abstraction model was extended to multi perception process and multiabstraction models were constructed by identifying the domains that the objects of the physical world W belong to. Furthermore, the domain relations between multiabstraction models W_i and W_j are formally defined from two points of view, i.e., the intersection of their objects sets is empty (there is no such an entity involved in two different domains); there are at least one entity involved in two different domains. The extended G KRA abstraction model enriches the representation of W compared with the model from a single point of view, it percepts W from the multiple one. Knowledge of various domains can be applied to achieving multiabstraction models and the reasoning ability is enhanced.
