Abstract
Online user communities exhibit distinct temporal dynamics in response to popular topics or breaking events. I want to introduce SEERA, an open-source end-to-end framework, to identify future user communities in a text streaming social network. SEERA models inter-user topical affinities at each time interval via streams of temporal graphs and learns temporal vector representations for users. This all takes place while users’ topics of interest and hence their inter-user topical affinities are changing over time. SEERA predicts yet-to-be-seen user communities based on the final positions of users’ vectors in the latent space. Notably, our framework serves as a one-stop-shop to future user communities for Social Information Retrieval and Social Recommendation systems. Empirical results on a Twitter dataset show the convenience of SEERA in building an effective news article recommender system.
Keywords: Community Prediction, Social Information Retrieval, Temporal Graph Embedding, News Article Recommendation
