【Abstract】 Online social networking is one of the most prominent features and main reasons of the big data era. In this paper, we first present the immense opportunities brought by big data in: advancing the technical level of the Chinese IT industry, leading development of the new Internet economy, and accelerating interdisciplinary research between sociology and information science. Next we analyze key issues in online social networks and point out new challenges of big social data research on semantic understanding and analysis, multi-modal association and fusion, group behavior analysis and mining, multidimensional analysis and visualization, and system development and integration. We then focus on introducing key international and domestic achievements in big data and online social networks. We conclude with a look at future trends in big social data analytics and mining.更多还原
