Contexts obtained from several expert opinions
Ana Burusco, Robin Gonzalez · 2002
Wille (1982) proposed a method to analyse the information presented through a table or context. His theory, called the formal concept analysis, allows us to classify the knowledge using hierarchies of concepts. From this point, we develop the L-fuzzy concept theory to study the contexts where the relationship between an object set and an attribute set is an L-fuzzy relation. In this paper, we attempt to represent the opinion of several experts in some objects and attributes and, to do it, we analyse the L-fuzzy concept theory in the case of a lattice of multisets L. Finally , we illustrate the results with an example.
