Recommender Systems Questions
The role of trust in personalized recommender systems with social trust is to enhance the accuracy and effectiveness of recommendations. Trust plays a crucial role in these systems as it allows users to rely on recommendations provided by others within their social network. By considering the trustworthiness of the recommender, the system can filter and prioritize recommendations based on the user's preferences and the trust they have in the sources. This helps in reducing information overload and increasing the likelihood of users accepting and acting upon the recommendations. Additionally, trust also fosters user engagement and satisfaction, as users are more likely to trust and value recommendations from sources they trust.
