Therefore, due to the abovementioned problems, the big data analysis using data mining and machine learning techniques should be considered in social network environment. We have finally selected nineteen manuscripts for this special issue after the first, second review processes. Each manuscript selected was blindly reviewed by at least three reviewers consisting of guest editors and external reviewers. The paper entitled BMulti-Scale Local Structure Patterns Histogram for Describing Visual Contents in Social Image Retrieval Systems,^by Baik et al. [1] proposes a local descriptor for personalized social image collections by utilizing twenty distinct structure patterns in salient edge maps at multiple scales. This allows both fine-grained and coarse-grained features to be
