{"product_id":"9789491216077","title":"Trust Networks for Recommender Systems","description":"This book describes research performed in the context of trust\/distrust propagation and aggregation, and their use in recommender systems. This is a hot research topic with important implications for various application areas. The main innovative contributions of the work are:\u003cbr\u003e-new bilattice-based model for trust and distrust, allowing for ignorance and inconsistency\u003cbr\u003e-proposals for various propagation and aggregation operators, including the analysis of mathematical properties\u003cbr\u003e-Evaluation of these operators on real data, including a discussion on the data sets and their characteristics.\u003cbr\u003e-A novel approach for identifying controversial items in a recommender system\u003cbr\u003e-An analysis on the utility of including distrust in recommender systems\u003cbr\u003e-Various approaches for trust based recommendations (a.o. base on collaborative filtering), an in depth experimental analysis, and proposal for a hybrid approach\u003cbr\u003e-Analysis of various user types in recommender systems to optimize bootstrapping of cold start users.","brand":"Atlantis Press","offers":[{"title":"Default Title","offer_id":47065028034800,"sku":"9789491216077","price":139.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9789491216077_p0.jpg?v=1763677819","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9789491216077","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
