On the use of Choquet integrals in the reduction of the size of L-fuzzy contexts

Studies about the reduction of the size of the L-fuzzy concept lattices have been addressed over the past. The number of objects and attributes of the L-fuzzy context is one of the most important factors that influence the size of the L-fuzzy concept lattice. In this paper, we tackle the problem of reducing the L-fuzzy context size. In order to do this, Choquet integrals can be a good tool for aggregating values. The possibility of giving importance not only to the individual observations, but also to the groups provides an appropriate way to solve the problem.
