Abstract

We present a new fuzzy extension of the classical effectiveness measures of information retrieval by a new way to calculate the relative cardinality of a fuzzy set. Previous approaches using Zadeh's cardinality are compared to our new approach in an experimental stage. The experiments have been carried out with a genetic algorithm where the fitness function to optimize is a combination of the fuzzy recall and fuzzy precision measures. Results included at the end of the paper show the goodness of our proposal.
