Online social software systems enable individuals to build representations of their network of social ties, and such information can be used for the analysis of network structure and the position of individuals in the network. However, social ties representing relationships as “friendship” have intensity or strength as an intrinsic, essential feature, and this needs to be taken into account in network models. This paper reports on fuzzy techniques that deal with imprecise information on the strength of social ties, and provides an extended model of brokerage that accounts for such imprecise information.
