The study of the \(L\)-fuzzy concept lattice. (English) Zbl 0827.06004

Summary: The \(L\)-fuzzy concept theory that we have developed in “Aplicación de técnicas \(L\)-fuzzy a la representación formal del conocimiento conceptual” [III Congreso Español sobre Tecnologías y Lógica Fuzzy, Santiago de Compostela (1993)] sets up classifications from the objects and attributes of a context through \(L\)-fuzzy relations. This theory generalizes the formal concept theory of R. Wille [“Restructuring lattice theory: An approach based on hierarchies of concepts”, Ordered sets, Proc. NATO Adv. Study Inst., Banff/Can. 1981, 445-470 (1982; Zbl 0491.06008)].
In this paper we begin with the \(L\)-fuzzy concept definition that generalizes the definitions of the formal concept theory, and we study the lattice structure of the \(L\)-fuzzy concept set, giving a constructive method for calculating this method. At the end, we apply this constructive method to an example that has been studied by other methods.
