Abstract

Many approaches to the trust study exist in literature. In our view,just a socio-cognitive approach to trust would be able to analyzethe sub-components (the basic beliefs) on which the final decisionto trust or not is taken. In this paper we show a firstimplementation and advance of the socio-cognitive model of trustdeveloped in [1, 2] using the so-called Fuzzy Cognitive Maps.With this implementation we show how the different componentsmay change and how their impact can change depending from thespecific situation and from the agent personality. We present acase study in the medical domain, with the choice between aDoctor and a Medical Automatic System. Another naturalapplication of the model is a classical collaborative scenario,where each agent needs to evaluate the trustworthiness of theother agents in order to collaborate or delegate a task.
