Image-oriented economic perspective on user behavior in multimedia social forums: An analysis on supply, consumption, and saliency

Abstract

This work addresses the novel problem of analyzing individual user's behavioral patterns regarding images shared on social forums. In particular, we present an image-oriented economic perspective: the first activity mode of sharing or posting on social forums is interpreted as supply; and another mode of activity such as commenting on images is interpreted as consumption. First, we show that, despite the significant diversity, images in social forums can be clustered into semantically meaningful groups using modern computer vision techniques. Then, users' supply and consumption profiles are characterized based on the distribution of images which they engage with. We then present various statistical analyses on real-world data, which show that there is significant difference between the images users supply and consume. This finding suggests that the flow of images on social network should be modeled as a bi-directional graph. In addition, we introduce a statistical approach to identify users with salient profiles. This approach can be useful for social multimedia services to block users with undesirable behavior or to identify viral content and promote it.

Social Psychological Analysis of College Students' Abnormal Consumption from the Perspective of "Social Identity"

“…The basic meaning of "social identity theory" is that an individual realizes that he belongs to a specific social group, and being a member of this group will bring him or her emotional and value significance [8]. As a research sample, the influencing factors of students' learning self-control are too complicated or have no universal research significance, so that the control level of irrelevant variables is required to be higher in the research [9]. Paying attention to education consumption and guiding people to establish a reasonable concept of education consumption is of great strategic significance to personnel training and social development.…”

“…Paying attention to education consumption and guiding people to establish a reasonable concept of education consumption is of great strategic significance to personnel training and social development. Therefore, the sample selection of regular school groups is not suitable for detailed research on the influencing factors of students' learning self-control at the micro level [9].…”
