The 5th WIT-EC workshop will be held together with the
Thirtieth AAAI Conference on Artificial Intelligence (AAAI-16),
February 12-17, 2016, in Phoenix, Arizona, 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)

Important Dates (hard deadlines):
Paper Submission Deadline : October 23, 2015
Notification of Acceptance: November 23, 2015
Camera-ready Paper: December 7, 2015
Workshop Date: February 12-13, 2016

Submission and Proceedings:

Papers must be formatted according to the AAAI 2016 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.

As previous years, we plan to invite the best papers for
a special issue for the Journal of Trust Management.
Information Systems Frontiers also becomes another venue
where selected and extended workshop papers can be recommended
for publication.

Previous Workshops:
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 has 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.
