Abstract

This paper introduces a new model for the representation of ontologies. We expose our own definition of the term ontology, and we define the concepts, objects, attributes and classes manipulated. Then, we introduce the notion of "specific difference", which is central in our work. Each concept owns a specific difference, which is an attribute belonging to it, and which constitutes its main characteristic. While representing a particular ontology, it allows to specify which characteristic is the most representative of a concept, in order to differentiate it from its siblings and to specialise it from its parent. An ontology by differentiation (using the specific difference) is therefore constituted by a hierarchy of concepts, each concept being defined from a more abstract one by the addition of a specific difference. The construction of such an ontology also implies the use of a methodology for the acquisition of knowledge. This aspect of our work is therefore developed in this paper. The methodology is defined as a combination of diverse existing techniques, which we adapt to the acquisition of ontologies by differentiation
