Abstract :
The article deals with a problem of modelling and propagating trust in trust networks (social networks, recommender systems, integrating systems). We briefly recall some of the solutions and approaches proposed by other authors and we focus on a trust model based on IFS theory (Atanassov´s intuitionistic fuzzy set theory). Then we present a draft of a method of calculating trust propagation with a use of a relative cardinality of IFS.
