Call For Papers

The issues of trust and reputation in multi-agent systems have received a lot of attention in the past. Also, formal methods to guarantee functional correctness, safety, and security as well as techniques to ensure reliability in distributed, self-organizing systems have been investigated by diverse research groups from different communities. Furthermore, the matter of the human as the user of self-organising and self-adaptive systems and the usability of such systems has been subject of research. These different facets of the same problem have so far been considered only separately and many have regarded security, safety, etc. as complementary to trust.

However, the overall trustworthiness of a self-organising system is connected to all the aforementioned properties and should be regarded holistically. The facets of trust qualify the relationships between the components of the system and between the user and the system. Functional correctness, security, safety, and reliability are facets that have to be ensured for the system's components as well as for the system as a whole. The classical notions of trust and reputation in MAS also apply to this relationship between system components. The relationship between the system and the user is influenced by the transparency and consistency of the system towards the user and most importantly by its usability, i.e., the way the user is informed about self-organising processes and allowed to interact with the system.

The nature of self-organising systems demands that issues of trust and its different facets become a primary concern. Many interacting adaptive entities, emergent behaviour, and a highly dynamic environment prompt the designer of such a system to consider trust in every aspect of the engineering process. Not only will a thorough consideration of trust yield a more robust and more secure system, but the incorporation of trust can also lead to gains with regard to performance and ease of use. In domains in which systems have to be certified, the formal treatment of trust and its facets in self-organising systems is a necessity.

The workshop will provide an open stage for discussions about the different facets of trust in self-organising systems, how every single one of them can be fostered, and how they relate. The workshop organizers are thus looking for submissions on any of the trust aspects mentioned above. Further examples for topics of interest are:

* Metrics of trust and specialised metrics for single trust facets
* Policies and their influence on trustworthiness
* Trust management systems for self-organising systems
* Formal methods to analyse, prove, or measure aspects of trust
* Trust and reputation in multi-agent systems
* Adaptive user interfaces
* Visualization of self-organisation processes
* Measuring and evaluating user trust in self-organising systems
* Engineering of trustworthy self-organising systems
* Evaluations of the effects of trust in self-organising systems

Aim of the Workshop

The aim of the workshop is to bring together researchers of different communities like Multi-Agent Systems, Autonomic Computing, and Organic Computing to discuss – based on high quality research papers and position papers – the different aspects of trust in self-adaptive and self-organising systems and to create a sense of the overarching concepts and problems that are associated with a holistic view on trustworthy self-organising systems. The workshop is an opportunity to promote this view and to engage in discussions about the interconnectedness of the different facets and their interplay in self-organising systems.


The workshop is aimed at researchers that have been investigating one of the trust aspects (functional correctness, safety, security, reliability, credibility, usability) in self-organising systems or that have been looking into trust and its different shapes. We explicitly encourage participation of researchers from different communities within computer science. The workshop will be set in an informal and cooperative atmosphere with ample time allotted to discussions.
