L-Fuzzy Concepts and linguistic variables in knowledge acquisition processes.⋆

Abstract. In this work, we analyze how the linguistic labels of a lin-guistic variable can be a useful tool in the L-Fuzzy Concept Theory. In concrete, we study the L-Fuzzy concepts obtained from a departure set represented by means of these linguistic labels applied to the set of objects or attributes. We also illustrate the results by means of an example. 1 Introduction. The Formal Concept Analysis developed by Wille ([18]) tries to extract some information from a binary table that represents a formal context (X,Y,R) with X and Y two finite sets (of objects and attributes, respectively) and R ⊆ X × Y. This information is obtained by means of the formal concepts which ar
