Bilattice-Based Aggregation Operators for Gradual Trust and Distrust
نویسندگان
چکیده
Trust and distrust are two increasingly important metrics in social networks. Since many of these networks are very large, it is only natural that not all users know each other. To this aim, propagation and aggregation operators are often used to estimate (dis)trust relations for users that are not directly connected through the network. In this paper, we introduce bilattice-based aggregation approaches and show that they can be used to accurately predict trust and distrust predictions for the social networking site CouchSurfing.org.

Practical aggregation operators for gradual trust and distrust
Trust and distrust are two increasingly important metrics in social networks, reflecting users’ attitudes and relationships towards each other. In this paper, we study the indirect derivation of these metrics’ values for users that do not know each other, but are connected through the network. In particular, we study bilattice-based aggregation approaches and investigate how they can be improve...
متن کاملOrdered Weighted Averaging Approaches for Aggregating Gradual Trust and Distrust
In this paper, we focus on the aggregation problem for (trust, distrust) couples in trust networks. In particular, we study approaches based on classical and induced ordered weighted averaging (OWA) operators.
متن کاملGradual trust and distrust in recommender systems
Trust networks among users of a recommender system (RS) prove beneficial to the quality and amount of the recommendations. Since trust is often a gradual phenomenon, fuzzy relations are the pre-eminent tools for modeling such networks. However, as current trust-enhanced RSs do not work with the notion of distrust, they cannot differentiate unknown users from malicious users, nor represent incon...
متن کاملTrust networks in recommender systems
Trust is not only essential in our daily lives, its importance in virtual networks should not be underestimated either. For example, we only use information found on the web when we trust the source, and we do not give our credit card details on sites we distrust. With the advent of the semantic web [2], intelligent web agents will be taking over more and more human tasks. Therefore, there is a...
