In this paper, in order to represent their connotative meaning, we explore vector based interpretations of the elements of an intuitionistic fuzzy set (IFS). Using one of these interpretations, we propose the spot-difference concept as a measure of differences between preferences about the membership and non-membership of each element. Considering the similarity as a concept related to the differences (the more differences, the less similarity), we make use of all the spot-differences to obtain a similarity measure. Additionally, we introduce the spot-differences footprint as a supplement to analyze the similarity between two IFSs.
