Generalized Separation Scores for Ranking Partially Ordered Data
摘要
The paper addresses the problem of scoring and ranking multidimensional ordinal data, by integrating existing “posetic” procedures, with tools from fuzzy logic. In particular, we consider and generalize the recently proposed separation scores, by computing them via triangular norms, the fuzzy logic equivalent of the classical set intersection operator \(\cap \) . The resulting scoring procedures is more consistent, from a mathematical point of view, and more flexible, in practical applications. Generalized separation scores are developed and illustrated through the analysis of a small real dataset, pertaining to political pluralism in Eurasia countries.
