'''ABSTRACT:'''
There is a rich literature on formal notions of trust. Each formalism often focuses on specific features of trust (e.g. the way trust is transmitted between agents) to obtain formal notions that can be applied in a computational framework. What is lacking, however, is a cohesive and comprehensive study of the notion of computational trust, one that singles out all the main features a computational notion of trust ought to possess. In this talk I will give a broad review of the current literature on computational trust, highlighting common features that the different notions of trust possess in those different formalism. The aim of the talk is to identify and make explicit all the features that are believed to be fundamental for a computational notion of trust. This should provide a starting base for a cohesive future research on trust in computational frameworks.

of trust. Ranging from cognitive models (where the mental states of trusting agents are the

base for trust values) to game-theoretic models (where trust depends on subjective

probabilities attributed to events), the literature on computational trust is a huge jungle of

ABSTRACT: There are numerous models that attempt to give a clear and precise formalisation of the notion of trust. Ranging from cognitive models (where the mental states of trusting agents are the base for trust values) to game-theoretic models (where trust depends on subjective probabilities attributed to events), the literature on computational trust is a huge jungle of different approaches and different representations of the notion of trust. Each one of those representations bear peculiar features that allows an application of the concept of trust to specific scenarios. Nonetheless, the literature suffers from a lack of cohesion both from a linguistic (different words for the same concepts) and from a theoretical point-of-view. My talk will focus on those issues, with an emphasis on the latter. The aim is to pin the core features of computational trust down, to obtain some necessary conditions each mathematical model ought to fulfil in order to qualify as a model of computational trust. Doing so will also give me the chance to clarify the terms involved, abstracting away from subtleties related to specific applications. The contribution of this talk is, therefore, two-fold: it provides a guide for newcomers to the subject, who will benefit from a linguistic clarification of the technical language of the subject, and it provides a solid starting point for all who wish to pursue research on computation trust.
