In this paper we shall propose a knowledge representation method, the deduction process in a knowledge representation and reasoning system using this method and therefore the answer function of such a system. This is an algebraic method because some concepts of universal algebra are used. More precisely, we introduce the concept of knowledge base with… (More)

In this paper we describe the structure of a distributed knowledge system organized on three levels. This description is based on the concept of semantic schema

In this paper we introduce the concept of cooperating system of semantic schemas. This structure is a tuple ({Si}i=1, E) (n ≥ 2) such that S1,. . .,Sn are distinct regular semantic schemas and E is a distinguished component. The formal computation in Si is a usual computation in a semantic schema and this kind of computation was defined in [3]. From the… (More)

In this paper we reconsider the computations accomplished in a semantic schema. We reconsider also the computations in a master-slave systems of semantic schemas introduced in [6] as a cooperating system of such structures. We show that a master-slave system is adequate to represent distributed knowledge. To relieve this fact we describe such a system named… (More)
