Polish Academy of Sciences}, language={eng}, abstract={In big systems, such as social networks or data integration systems, a matter of trust or reliability is significant when assesing the value of information that one source is receiving from other sources. As it was disscused in a literature, the most natural way to model trust is to model it in a dual and gradual form of trust and distrust degrees. Such duality can be represented in a convienient way by a theory of Attanassov’s intuitionistic fuzzy sets (IFSs theory) and this representation is discussed in the present article. Moreover, the article deals with a problem of trust propagation and presents a new way of propagation based on relative scalar cardinality of IFSs.}, type={Text}, title={Developments in fuzzy sets, intuitionistic fuzzy sets, generalized nets and related topics.
