The 25th ACM Symposium on Applied Computing
22 - 26 March 2010, Sierre, Switzerland

Track: Trust, Reputation, Evidence and other Collaboration Know-how (TRECK)

Proceedings: ACM printed form, ACM CD-ROM and ACM digital library

Aims and scope of the TRECK track:

Computational models of trust and online reputation mechanisms have  
been gaining momentum. The ACM SAC 2005, 2006, 2007, 2008 and 2009  
TRECK tracks attracted researchers from both academia and industry who  
have joined an online group at

The goal of the ACM SAC 2010 TRECK track remains to review the set of  
applications that benefit from the use of computational trust and  
online reputation. Computational trust has been used in reputation  
systems, risk management, collaborative filtering, social/business  
networking services, dynamic coalitions, virtual organisations and  
even combined with trusted computing hardware modules. The TRECK track  
covers all computational trust/reputation applications, especially  
those used in real-world applications.

The topics of interest include, but are not limited to:

- Recommender and reputation systems

- Trust management, reputation management and identity management

- Pervasive computational trust and use of context-awareness

- Mobile trust, context-aware trust

- Web 2.0 reputation and trust

- Trust-based collaborative applications

- Automated collaboration and trust negotiation

- Trade-off between privacy and trust

- Trust/risk-based security frameworks

- Combined computational trust and trusted computing

- Tangible guarantees given by formal models of trust and risk

- Trust metrics assessment and threat analysis

- Trust in peer-to-peer and open source systems

- Technical trust evaluation and certification

- Impacts of social networks on computational trust

- Evidence gathering and management

- Real-world applications, running prototypes and advanced simulations

- Applicability in large-scale, open and decentralised environments

- Legal and economic aspects related to the use of trust and  
reputation engines

- User-studies and user interfaces of computational trust and online  
reputation applications

Submission guidelines are posted on the TRECK 2010 Web site  
(, which always contains the latest  

Authors are invited to submit full papers about original and  
unpublished research. A paper cannot be submitted to more than one  
track. We would like to encourage the submission of industrial  
experience reports and reports of innovative applications.

The body of each paper should not exceed 5,000 words.

Submissions should be properly anonymized to facilitate blind reviewing.
At least three reviewers will be assigned to each submission to the  
TRECK track.
