Abstract

The important step of model-based reasoning is to construct the abstraction model of physical world. In this paper, we introduce the concept of hierarchical ontology classes within the G-KRA model framework to realize the modeling knowledge sharing and reuse. Three kinds of ontology operators are defined and the formal process of them working is partly given. We also point out that constructing hierarchical ontology classes can be independent of the modeling process. Moreover we show how to automatically build up a hierarchical model of a world W based on the hierarchical ontology classes which is as well updated during the modeling. We expect that this work will rich the way to construct hierarchical model of physical world automatically and efficiently.
