Reputation Put to the Test: a Testcase for a Cognitive Reputation Model

Abstract—The wide diffusion of open and decentralized environments like the Web makes it possible for actors to interact with previously unknown peers. As a consequence, trust has become a hot topic in the field of computer science. Many attempts to formalize concepts like trust and reputation have been carried out in the literature, most remarkably the one by Herzig et al. [5]. However, Herzig et al. focus on describing a conceptual framework but do not provide any concrete instantiation of it, thereby not showing any evidence about the effectiveness of their approach. This paper fills the gap by presenting such an instantiation based on agent technologies. Although our instantiation targets a Wikipedia-related scenario and exploits the Jason [1] and CArtAgO [13], [14] frameworks, the methodology we present is general and can be applied to different scenarios and agent technologies.
