Abstract:

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.

Key words: abstraction model, general KRA abstraction model, multiabstraction model, domain relation
