This work suggests the use of multi-linear regression for determining the weights of individual criterion and computing the overall ratings of each item in multi-criteria CF for enhancing its accuracy through multi- linear regression.

Abstract

Recommender system (RS) is a web personalization tool for recommending appropriate items to users based on their preferences from a large set of available items. Collaborative filtering (CF) is the most popular technique for recommending items based on the preferences of similar users. Most of the CF based RSs work only on the overall rating of the items, however, the overall rating is not a good representative of user preferences for an item. Our work in this paper, is an attempt towards incorporating of various criteria ratings into CF i.e., multi-criteria CF, for enhancing its accuracy through multi-linear regression. We suggest the use of multi-linear regression for determining the weights of individual criterion and computing the overall ratings of each item. Experimental results reveal that the proposed approach outperforms the classical approaches.

This work proposes to use Support Vector regression to determine the relative importance of the individual criteria ratings and proposes to combine user- and item-based regression models in a weighted approach, which outperforms both recent single-rating algorithms based on matrix factorization and previous methods based on multi-criteria ratings in terms of the predictive accuracy.

According to real data-based experiments, it is possible to produce more accurate recommendations by utilizing multi-criteria item-based collaborative filtering algorithm instead of a single criterion rating-based algorithm.
