Guest editorial: Recent advances on big social data

摘要

Big data has been an important issue in information science communities. Recently, limits on the size of datasets that are feasible to process in a reasonable amount of time were on the order of exabytes of data. Scientists in many different domains (e.g. meteorology, genomics, connectomics, complex physics simulations, and biological and environmental research) regularly encounter limitations due to large datasets. In particular, these limitations strongly affect social network applications (e.g. Internet search, finance and business informatics). Social Understanding and Mining has been a complex and hot topic for a large number of research areas in recent years.
