Chapter 2 MULTIMEDIA INFORMATION NETWORKS IN SOCIAL MEDIA

The popularity of personal digital cameras and online photo/video sharing community has lead to an explosion of multimedia information. Unlike traditional multimedia data, many new multimedia datasets are organized in a structural way, incorporating rich information such as semantic ontology, social interaction, community media, geographical maps, in addition to the multimedia contents by themselves. Studies of such structured multimedia data have resulted in a new research area, which is referred to as Multimedia Information Networks (MINet). MINets are closely related to social networks, but especially focus on understanding the topics and semantics of the multimedia files in the context of network structure. This chapter reviews different categories of recent MINet systems, summarizes the popular inference methods used in recent works, and discusses the applications related to MINets. We also discuss a wide range of topics including public datasets, related industrial systems, and potential future research directions in this field.
