An interactive tool based on priority semantic networks

The main advantages of the semantic networks as formalism for knowledge representation are well known: simplicity, naturalness, visionless, and clarity. However, they have the following disadvantages: poor representation of arbitrary relations, insufficient expressiveness, unclear semantics, difficult implementation of some operations, and difficult control of the inheritance. In the present paper, the formal definition of a new kind of semantic network, called Priority Semantic Network (PSN) is given. On this basis, an algorithm of transformation of PSN into a list of concepts and semantic links is presented. The architecture and user interface of a tool, in which this algorithm is embedded, are also discussed.
