Title:  Collective-decision Making in Social Networks and its Resistance to Bribery

Speaker: Ms. Bayan Alarifi, Software Engineering Department, CCIS.

Abstract:.

The emergence of virtual communities created a need to better understand social relations and their dynamics in the online world. A line of research has been devoted to understand these virtual interaction spaces as they come with different aspects to what we have in real life, such as anonymity. Sociological concepts such as friendship, bribery, trust and reputation can have a significant effect on the online user experiences. Thus, a mature understanding can inspire a much more efficient and effective take on the design of multi-agent social systems today. This work studies trust relations and collective-decision making where individuals are influenced by their peers in forming their opinions, looking at what happens when a malicious external agent bribes certain individuals in order to misrepresent their evaluation, and therefore influence all their friends. A quantitative model, and a tool is developed to show whether or not a certain social network is bribery-proof, and suggest the best bribing strategy that can be applied, through game theoretic reasoning.
