In the present paper, we introduce an extension of the conceptual graph model suitable to the representation 7 of data which are modelized using fuzzy sets. We extend the specialization relation of the conceptual graph model to fuzzy conceptual graphs. Lastly we introduce a new way of comparing conceptual graphs, using the 9 idea that a graph may be(More)

— This paper presents a new type of fuzzy sets, called " Hierarchical Fuzzy Sets " , that apply when the considered domain of values is not " flat " , but contains values that are more specific than others according to the " kind of " relation. We study the properties of such fuzzy sets, that can be defined in a short way on a part of the hierarchy, or(More)
