The use of two relations in L-fuzzy contexts

C Alcalde, A Burusco, R Fuentes-González - Information Sciences, 2015 - Elsevier
In the analysis of relations among the elements of two sets it is usual to obtain different
values depending on the point of view from which these relations are measured. The main …

Study of the Relevance of Objects and Attributes of L-fuzzy Contexts Using Overlap Indexes
