Abstract

Trustworthiness in Online Social Networks has become essential to discriminate the goodness of both different information as well as the users it originates. Here a model for news spreading in directed online social networks (OSNs) that takes into account trustworthiness-related issues is introduced. In particular we add a credibility network on top of the acquaintance network naturally present in OSNs to model the changing of each node’s opinion about his/her neighbors every time a piece of news comes from them over the OSN. We examine three different scenarios of news spreading over OSNs and propose a model suitable for each scenario, evaluating its applicability using a real world weighted directed network.
