The 4th WIT-EC workshop will be held together with the Twenty Ninth AAAI Conference on Artificial Intelligence (AAAI-15), January 25-26, 2015, in Austin, Texas, USA. 

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 by the above organizers together with the 13th ACM Conference on Electronic Commerce (EC’12), on June 4-8, 2012, in Valencia, Spain. We were able to attract 11 high quality submissions, 8 of which were accepted for presentation at the workshop. The second Workshop on Incentive and Trust in E-commerce (WIT-EC’13) has been held together with the 23rd International Joint Conference on Articial Intelligence (IJCAI’13), on August 3-9, 2013, in Beijing, China. The third Workshop on Incentive and Trust in E-Communities (WIT-EC’14) will be held together with the 28th Conference on Articial Intelligence (AAAI’14), on July 27 , in Quebec, Canada. We were able to attract 13 high quality submissions, 9 of which were accepted for presentation at the workshop.

Important Dates: 
Paper Submission Deadline : October 07, 2014 
Notification of Acceptance: November 14, 2014 
Camera-ready Paper: November 21, 2014 
Workshop Date: January 25, 2015 

Submission and Proceedings: 
Papers must be formatted according to the AAAI 2015 style guide. 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. 

For the first two series (2012 and 2013) of the WIT-EC workshops, we had a special issue of the Computational Intelligence journal on “Incentives and Trust in E-Commerce”. 

Starting from 2014, our workshop will have a continuing series of special issues at the Journal of Trust Management. The best 4-5 papers in each year will be recommended to be extended and included in that year’s special issue. 

Another future plan for the workshop is to have a book composed of the relevant papers from the workshop as book chapters. This plan will be discussed during the 2015 workshop.
