The 2nd WIT-EC workshop will be held together with the 23rd International Joint Conference on Artificial Intelligence (IJCAI'13), August 3-9, 2013, in Beijing, China.

With the growth of electronic marketplaces, frauds in e-markets are on the rise. Some possible sources of frauds could be: 1) anonymous identities of trading parties; 2) uncertainty about quality of products due to the asymmetry of information between trading parties; and 3) the lack of interpersonal interactions among them in e-markets.

Trust and reputation mechanisms seem to be effective solutions to enhance the performance of participants in e-markets. However, they cannot show their full functionalities without proper contributions of participants in providing honest information about each other. Therefore, trust and reputation mechanisms should be accompanied with self-enforcing mechanisms in order to provide sufficient incentives for participants to disseminate and share their truthful information. On another hand, trust and reputation measures are often used as part of incentive mechanisms to promote honesty in e-markets. Thus, trust and incentives have such a bidirectional relationship.

The main objective of this workshop is 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.


Topics of interest include, but are not limited to:

- Social, cognitive and computational trust, reputation and inventive models
- Robustness of trust, reputation and incentive mechanisms
- Attacks on, and defences for, trust, reputation and incentive mechanisms
- Cross-cultural approaches
- Components and dimensions of socio-technical trust
- Game theoretic approaches to trust and reputation
- Risk management and trust
- 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
- Evolution of trust
- Trust-based incentive mechanisms
- User interfaces to incentive mechanisms


Previous Workshop

Reacting to the strong needs and trend, the Workshop on Incentives and Trust in E-Commerce (WIT-EC'12 (http://trust.sce.ntu.edu.sg/wit-ec12) was organized by the above organizers together 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. 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.
