Recommender Systems Questions
The role of social trust in recommender systems is to enhance the accuracy and effectiveness of recommendations by incorporating social connections and recommendations from trusted individuals. Social trust allows users to rely on recommendations from friends, family, or other trusted sources, leading to a higher likelihood of acceptance and satisfaction with the recommended items. It helps overcome the cold-start problem and information overload by filtering and prioritizing recommendations based on the trustworthiness of the sources. Additionally, social trust can foster a sense of community and engagement within the recommender system, as users can discover new items through their trusted connections and share their own recommendations with others.
