Topic: Game with a Purpose Abstract In recent years, human computation has emerged to be a potent approach for solving many challenging problems that computer automation was not able to address efficiently. The famous example of CAPTCHA, in which people identify alphanumeric characters for authentication purposes while simultaneously (and unconsciously) contribute to digitizing pre-computer age publications, is one of the most impactful use of human computation. In this talk, I will share our experience in building a gamified environment for serious research purposes to harness the power of human computation. Our serious game platform is designed around the principles of Congestion Game Theory to study human strategies in task delegation under various conditions. Equipped with unobtrusive data collection technology, our platform has collected a large scale dataset of over 150,000 decision trajectory data records from 2,700 games played by over 400 unique users so far. Preliminary analysis has yielded interesting results that can have significant implications for research in designing human-inspired resource allocation strategies which are important to network optimization.

Topic: Interaction Group Identification in Social Networks - A Game-Theoretic Approach Abstract There are often enormous interactions among users of online social networking services. Based on their interactions and the corresponding contents, the users can be clustered into interaction groups with different interests. In this study, we propose a game-theoretic approach to formulating the dynamics of users' participation into interaction groups on a social network formed by users' interrelationships. A partition of the social network into interaction groups corresponds to an equilibrium of the game. In the proposed approach, each node is represented by a selfish agent that performs actions to join or leave interaction groups according to its utility. For the purpose of validation, we conduct experiments on a real-world data set collected from Facebook. The experimental results demonstrate the effectiveness of the proposed approach in identifying interaction groups in social networks. Dr. Jin is an Associate Professor with the CAS Key Lab of Network Data Science and Technology, Institute of Computing Technology, Chinese Academy of Sciences (CAS). He obtained the Ph.D. degree in computer science from Hong Kong Baptist University in 2005. His research interests include social computing, multi-agent systems, performance modelling and evaluation. He has published over 95 papers in international journals, including IEEE ToC, IEEE TWC, IEEE TPDS, and conferences, including CIKM, WWW, AAMAS, ICC, AINA. He co-authored two monographs published by Springer and Tsinghua University Press in 2004 and 2003, respectively. He received the IEEE Best Paper Award at the IEEE 21st International Conference on Advanced Information Networking and Applications (AINA'07). He has served on the technical and executive committees of more than 50 conferences and workshops.
