Workshop on Dynamic SOcial Networks (DySON)

Monday, 8 June 2015 • 09:00 – 13:00

WS-27: Dynamic Social Networks (DySON)

Organizer: Symeon Papavassiliou (National Technical University of Athens, Greece)

Social cyber-physical and mobile networks have gained considerable interest. They are now well-known as the principal channels for communication, increasing marketing potentials, tools for enabling social research, and policy forums, all of which eventually indicate a more than ever increasing penetration of networks in human lives. DySON mainly covers the technical aspects of the interplay between social and wireless mobile and other cyber-physical networks, and focuses on original contributions regarding their structure, behavior, and optimization. Emphasis is placed on the interplay between social and mobile wireless networks. DySON, will present the highest quality contributions regarding analysis, control and optimization from the perspective of complex network analysis, promoting the most interesting interdisciplinary and cross-disciplinary analytical methodologies. DySON is centered both on formal methods, as well as on noteworthy technical contributions of more practical flavor. It will present papers combining knowledge from several fields and addressing the corresponding challenges, while opening new frontiers and opportunities in relevant research.

WS-27-02: Keynote: Timelines Analysis and competition over popularity, influence and visibility in social networks.

Room: ICC Capital Suite 2

Chair: Francesco De Pellegrini (Create-Net, Italy)

The major social networks use timelines to display content that a user receives from those sources that he follows. A content that arrives at a timeline is placed at the top of the list and each other content is pushed down by one step. If the timeline is finite (as in twitter) then this causes the last element in the timeline to be pushed out. Moreover, the lower the content is on the timeline the smaller its influence is. In this talk we shall first present analysis of the timeline process and of the probability to be visible on the timeline. We shall further describe the influence process of content which takes into account not only the location on the timeline but also aging of content. We shall then study the impact of the burstiness of the arrival of contents on the timeline process. We shall finally introduce game theoretical models to describe the competition over popularity and over visibility of content in the timeline. We shall study two specific game theoretic problems. The first is a timing game: when is it best to send a content. The second is a resource allocation game for optimal control of the flow of content.The work describes ongoing collaborative work with many co-authors: Alexandre Reiffers, Nahum Shimkin, Anurag Kumar, Yezekael Hayel and others.
