This study describes and evaluates a novel trust model for a range of collaborative applications. The model assumes that humans routinely chose to trust their peers by relying on few recurrent presumptions, which are domain independent and that form a recognisable trust expertise. We refer to these presumptions as trust schemes, the specialised version of Walton’s argumentation schemes. Experimental evidence is provided about trust schemes efficacy with a detailed experiment over an online community of 80.000 members. Results show how proposed trust schemes are more effective in trust computation when they are combined together and when their plausibility in the selected context is considered.
