These datasets include ratings as well as social (or trust) relationships between users. Data are from LibraryThing (a book review website) and epinions (general consumer reviews). Those specific user ratings allow for detailed analysis of user preferences. By capturing the social (or trust) relationships between users, this dataset enables the study of how social connections influence user behavior and recommendations.
