Abstract: To deal with the challenges of information diffusion pattern mining problem which the communication content is unknown and innocent data occupies a very high ratio of the observed data, the article proposes a probability model predicting the relativity of the communications between users, which infers the information diffusion. In addition, it proves the inferring problem NP-hard, and proposes NetMine algorithm to get a near optimal solution. Experiments show that the proposed NetMine algorithm outperforms other state-of-art algorithms.
