A Fuzzy-Based Inference Mechanism Of Trust For Improved Social Recommenders, Renato Costa, Luiz Fernando Capretz

Electrical and Computer Engineering Publications

This paper presents a stochastic model based on Monte Carlo simulation techniques for measuring the performance of recommenders. A general procedure to assess the accuracy of recommendation predictions is presented and implemented in a typical case study where input parameters are treated as random values and recommender errors are estimated using sensitive analysis. The results obtained are presented and a new perspective to the evaluation and assessment of recommender systems is discussed.
