Abstract

The discovery of community structures in social networks has gained significant attention since it is a fundamental problem in understanding the networks’ topology and functions. However, most social network data tend to be collected from partially observable networks. In this seminar, I address a new problem of seamlessly detecting community structures in the context of such an incomplete network, which deals with a non-trivial integration of graph recovery and community detection. Our proposed framework consists of 1) estimation of the missing part of the network, 2) selection and addition of influential nodes by ranking, and 3) discovery of community structures. The benefits from resulting more complete community structures are finally investigated.
