Expansible measures of specificity
Ronald R. Yager · International Journal of General Systems · 2012
We introduce the measure of specificity and describe its basic features. We discuss the class of linear specificity measures. We note that while this class of specificity measures is very useful for comparing the quality of information about variables over the same domain they can have some difficulties when the variables have domains of different cardinality. In order to handle these types of comparisons, we need expansible specificity measures. After formalizing the property of expansibility, we suggest a number of expansible specificity measures.
