- W4285153821 abstract "Recommender systems (RSs) are utilized by various e-commerce giants such as Amazon, YouTube and Netflix for providing a personalized experience to the individual users. For this reason, it has become very important to develop and use efficient techniques to provide recommendations. Neighborhood-based collaborative filtering approaches are traditional techniques for recommendations and are very popular due to their simplicity and efficiency. Neighborhood-based recommender systems use numerous kinds of similarity measures for finding similar users or items. Further, defining novel ways to model the notion of similarity is an active thread of research among RS researchers (by using rating data available in the user-item matrix). This work compares and analyzes the performance of various Jaccard-based similarity measures. Primarily, various Jaccard-based similarity measures are examined with their authoritative definitions. We have conducted various experiments using standardized benchmark datasets (MovieLens-100 K, MovieLens-1 M, and Yahoo music) for assessing the performance of these measures. Empirically obtained results demonstrate that the New Weighted Similarity Measure (NWSM) provides better predictive accuracy among all measures." @default.
