The study of trust has advanced tremendously in recent years, to the extent that the goal of a
more unified formalisation of the concept is becoming feasible. To that end, we have begun …

Trust is a judgement of unquestionable utility-as humans we use it every day of our lives.
However, trust has suffered from an imperfect understanding, a plethora of definitions, and …

Trust allows the behavior evaluation of individuals by setting confidence values, which are
used in decisions about whether or not to interact. They have been used in several fields …

Trust and reputation are two distinct social constructs of high complexity that have been
studied for decades in different areas of knowledge. In order to allow for efficient models of …

The ReGreT system is a trust and reputation mechanism that uses, among other things,
social information to improve the calculation of trust and reputation measures. Using a …

Trust models as thus far described in the literature can be seen as a monolithic structure: a
trust model is provided with a variety of inputs and the model performs calculations, resulting …

Artificial agents do not exist in the world in solitude. They are required to interact with others,
and thus must reason in some fashion about those they interact with. This paper presents a …

We argue that the notion of trust, as it figures in an ethical context, can be illuminated by
examining research in artificial intelligence on multi-agent systems in which commitment …

Computational trust mechanisms aim to produce trust ratings from both direct and indirect
information about agents' behaviour. Subjective Logic (SL) has been widely adopted as the …

To describe the concept of transitive trust in a simplified way, assume that agent A trusts
agent B, and that agent B trusts agent C, then by transitivity, agent A trusts agent C. Trust …
