A Multi-dimensional and Event-Based Model for Trust Computation in the Social Web

In this paper, we propose a general-purpose Trust Layer that fits and exploits the emerging concept of Social Web. Key features of our proposal are the consideration of several dimensions for trust computation and the exploitation of social interaction dynamics over the Web, through the definition and the evaluation of event patterns and trust rules. Besides presenting our trust model, we discuss a case study on the ACM Digital Library social environment.
