The use of linguistic variables and fuzzy propositions in the LL-Fuzzy concept theory

The use of linguistic variables and fuzzy propositions in the interval-valued LL-Fuzzy contexts can be an interesting tool to extract a more complete information from them. In this paper, we analyze three different situations. First, we obtain significant relations in order to study all the objects and attributes of the interval-valued LL-Fuzzy context by means of the interval-valued LL-Fuzzy concepts. After that, we show how to replace the erroneous values to be able to study in a suitable way the context. Finally, we use the linguistic labels to obtain a subcontext that represents our interest of study. We also show an experimental evaluation in the paper.
