ABSTRACT
Trust-based recommender systems emerged as a solution to different limitations of traditional recommender systems. These social systems rely on the assumption that users will adopt the preferences of users they deem trustworthy in an online social setting. However, most trust-based recommender systems consider trust to be a static notion, thereby disregarding crucial dynamic factors that influence the value of trust between users and the performance of the recommender system. In this work, we intend to address several challenges regarding the dynamics of trust within a social recommender system. These issues include the temporal evolution of trust between users and change detection and prediction in users’ interactions. By exploring the factors that influence the evolution of human trust, a complex and abstract concept, this work will contribute to a better understanding of how trust operates in recommender systems.

Understanding the moderating roles of types of recommender systems and products on customer behavioral intention to use recommender systems
This study investigates how consumers assess the quality of two types of recommender systems-collaborative filtering and content-based--in the context of e-commerce by using a modified version of the unified theory of acceptance and use of technology (...
Trust-based collaborative filtering: tackling the cold start problem using regular equivalence
RecSys '18: Proceedings of the 12th ACM Conference on Recommender SystemsUser-based Collaborative Filtering (CF) is one of the most popular approaches to create recommender systems. This approach is based on finding the most relevant k users from whose rating history we can extract items to recommend. CF, however, suffers ...
Multi-faceted trust and distrust prediction for recommender systems
Many trust-aware recommender systems have explored the value of explicit trust, which is specified by users with binary values and simply treated as a concept with a single aspect. However, in social science, trust is known as a complex term with ...
