报告摘要：

In this talk, we propose a new class ofclustered temporal point process model to model the posting patterns of usersof Sina Weibo, the largest twitter-type online social media in China. Theproposed model captures both inhomogeneity in the initial posting time as wellas the clustering pattern in the subsequent posts following the initial post.We develop two EM-type algorithms for estimating the parameters in the proposedmodel, based on which we cluster the different user patterns. We apply ourproposed methods to two social media datasets.
