Properties Analysis of Inconsistency-based Possibilistic Similarity Measures
Ilyes Jenhani, Salem Benferhat, Zied Elouedi.
This paper deals with the problem
of measuring the similarity degree
between two normalized possibility
distributions encoding preferences or
uncertain knowledge. Many existing
definitions of possibilistic similarity
indexes aggregate pairwise distances
between each situation in possibility
distributions. This paper
goes one step further, and discusses
de nitions of possibilistic similarity
measures that include inconsistency
degrees between possibility distributions.
In particular, we propose a
postulate-based analysis of similarity
indexes which extends the basic ones
that have been recently proposed in
a literature.
