\ Trust is an essential feature of any system where entities have to\ collaborate among them. Trust can assist entities making decisions\ about what is the best entity for establishing a certain collaboration.\ It would be desirable to simulate behaviour of users as in social environments\ where they tend to establish relationships or to trust users\ who have common interests or share some of their opinions, i.e., users\ who are similar to them to some extent. Thus, in this paper we first\ introduce the concept of context similarity among entities and from it\ we derive a similarity network which can be seen as a graph. Based\ on this similarity network we dene a trust model that allows us also\ to establish trust along a path of entities. A possible applications of\ our model are proximity-based trust establishment. We validate our model in this scenario.

During the last years, many trust and reputation models have been proposed, each one targeting different contexts and purposes, and with their own particularities. While most contributions focus on defining ever-increasing complex models, little attention has been paid to the process of building these models inside applications during their implementation. The result is that models have traditionally considered as ad-hoc and after-the-fact solutions that do not always fit with the design of the application. To overcome this, we propose an object-oriented development framework onto which it is possible to build applications that require functionalities provided by trust and reputation models. The framework is extensible and flexible enough to allow implementing an important variety of trust models. This paper presents the framework, describes its main components, and gives examples on how to use it in order to implement three different trust models.
