We present an extended trust model for detecting malicious activities in online social networks. The major idea is to perform a trust propagation process over a heterogeneous social graph in which different social activities are well modeled. We develop two trustworthiness measures and evaluate their performance of detecting malicious activities using a real Twitter data set.
