Abstract
Billions of user images, which are shared on social media, can be widely accessible by others due to their sharing nature. Using machine-generated labels to annotate those images is a reliable for user connections discovery on social networks. The machine-generated labels are obtained from encoded vectors using up-to-date image processing and computer vision techniques, such as convolution neural network. By analyzing 2 million user-shared images from 8 online social networks, a phenomenon is observed that the distribution of user similarity based on their shared images follows exponential functions. Users who share visually similar images are likely having follower/followee relationships, regardless of the origins and the content sharing mechanisms of a social network. This phenomenon is nicely formulated for a multimedia big data recommendation engine as an alternative to social graphs for recommendation. By utilizing the formulation of the distribution, it is proven the proposed engine can be 46% better than previous approaches in F1 score and achieves a comparable performance of friends-of-friends approach. To the best of our knowledge, this is the first attempt in related fields to characterize such phenomenon by massive user-shared images collected from real-world SNs, and then formulate into practical analytics engine for connection discovery.
