The aim of this paper is to present a logical framework in which the concepts of trust and
reputation can be formally characterized and their properties studied. We start from the …

Evaluating trust in Multi-Agent Systems (MASs) is of prime importance for the success of
agent-based applications where agents interact and operate in uncertain and dynamic …

We propose a method for constructing Dempster-Shafer belief functions modeling the trust of
a given agent (the evaluator) in another (the target) by combining statistical information …

Trust is a mechanism for managing the uncertainty about autonomous entities and the
information they store, and so can play an important role in any decentralized system. As a …

Large-scale multiagent systems have the potential to be highly dynamic. Trust and
reputation are crucial concepts in these environments, as it may be necessary for agents to …

Computational trust and reputation models have been recognized as one of the key
technologies required to design and implement agent systems. These models manage and …

Abstract Information provided by a source should be assessed by an intelligent agent on the
basis of several criteria: most notably, its content and the trust one has in its source. In turn …

Trust is an extremely helpful construct when reasoning under uncertainty. Thus, being able
to logically formalize the concept in a suitable language is important. However, doing so is …

Trust is used to minimise the uncertainty in the interactions of the agents especially in case
of conflicting information from different sources. Besides conflicts among information there …

Before presenting the contents of the special issue, we propose a structured introductory
overview of a landscape of the weighted logics (in a general sense) that can be found in the …
