Sorry for multiple copies. The submission deadline of the AAAI WIT-EC 2014 has been extended to April 25, 2014. CALL FOR PAPER AAAI 2014 WORKSHOP ON INCENTIVE AND TRUST IN E-COMMUITIES (WIT-EC'14) http://trust.sce.ntu.edu.sg/wit-ec14/ The 3nd WIT-EC workshop will be held together with the Twenty-Eighth AAAI Conference on Artificial Intelligence (AAAI'14), July 27-31, 2014, in Quebec, Canada. Trust and incentive have bidirectional relationships. As trustworthiness measures are used as part of incentive mechanisms to promote honesty in electronic communities, incentive mechanisms motivate participants to contribute their truthful opinions that are useful for trust modeling. Hence, trust and reputation systems should not only provide a means to detect and prevent malicious activities but also design a mechanism to discourage dishonesty attitudes amongst participants. The evidential success of combining these two concepts inspires and encourages researchers in the trust community to enhance the efficacy and performance of trust modeling approaches by adopting various incentive mechanisms. The main objective of this workshop is to bring together researchers and practitioners of both fields, to foster an exchange of information and ideas, and to facilitate a discussion of current and emerging topics relevant to building effective trust, reputation and incentive mechanisms for electronic communities. Topics of interest include, but are not limited to: - Social, cognitive trust, reputation - Computational trust, reputation - Incentive Mechanisms - Cross-cultural approaches - Components and dimensions of sociotechnical trust - Game theoretic approaches to trust and reputation - Game theory and trusting behaviours - Risk management and trust-based decision making - Trust management dynamics - Trust, regret, and forgiveness - Economic drivers for trustworthy systems - Trust and economic models - Trust metrics assessment and threat analysis - Context-aware trust assessments - Trust-aware recommender systems - Evolution of trust - Trust-based incentive mechanisms - Robustness of trust and reputation systems - Trust metrics assessment and threat analysis - Robustness of incentive mechanisms - Deception and fraud, and its detection and prevention - Attacks on, and defences for, trust, reputation and incentive mechanisms - Testbeds and framework of trust - User interfaces to incentive mechanisms - Real-world applications for virtual communities (e.g. e-commerce, social network, e-health, e-learning, blog, online tutoring systems) Previous Workshops: Reacting to the strong needs and trend, the first Workshop on Incentives and Trust in E-Commerce (WIT-EC'12) was organized with the 13th ACM Conference on Electronic Commerce (EC'12), on June 4-8, 2012, in Valencia, Spain, to bring together researchers in both the area of game theory for designing incentive mechanisms and the area of trust and reputation modeling, towards the design of more effective trust, reputation and incentive mechanisms for creating safe e-marketplace environments. The second Workshop on Incentive and Trust in E-commerce has been held together with the 23rd International Joint Conference on Artificial Intelligence (IJCAI'13), on August 3-9, 2013, in Beijing, China. Following up the success of the WIT-EC'12 workshop, we invite eight accepted papers to the special issue of Computational Intelligence on Incentives and Trust in E-Commerce ( http://www.ntu.edu.sg/home/zhangj/doc/cfp-ci-si-trust.pdf ) aiming to further elicit articles in a more comprehensive and extended form that contribute to the resolving of the above mentioned challenges.

We solicit short and long papers as well as research demos. Long papers (6 pages) present original research work; short papers (4 pages) report on work in progress or describe demo systems. All the selected papers will be published in an AAAI technical report volume. Submissions will be reviewed for relevance, originality, significance, validity and clarity. All articles selected for publication will be reviewed by at least two reviewers with expertise in the area. As previous years, we plan to invite the best papers for a journal special issue.
