Possibilities and Limitations of Modeling Trust and Reputation

Abstract. We all highly depend and rely on the trustworthiness of information and services provided by various parties and institutions. Reputation systems are one possibility to support individuals in distinguishing trustworthy partners from malicious and unreliable parties. In this paper, we discuss possibilities and limitations of different types of reputation systems and their underlying trust models. We address in especially the properties of trust relations, the quantification and representation of trust values as well as reasoning and computation with trust.
