Seventh International Workshop on Trust in Agent Societies
To be held at Autonomous Agents & Multi-Agent Systems Conference
(AAMAS 2004) Submission deadline: Thursday 1 April 2004 DESCRIPTION OF THE WORKSHOP The aim of the workshop is to bring together researchers who can contribute to a better understanding of trust and reputation in agent societies. Most agent models assume secure and reliable communication to exist between agents. However, this ideal situation is seldom met in reality. In fact, many techniques (e.g. contracts, signatures, long-term personnel relationships, reputation) have been evolved over time to detect and prevent deception and fraud in human communication, exchanges and relations, and hence to assure trust between agents. Artificial societies will need analogous techniques. Trust is more than secure communication, e.g., via public key cryptography techniques. For example, the reliability of information about the status of your trade partner has little to do with secure communication. With the growing impact of electronic societies, trust and privacy become more and more important. Trust is important in applications such as human-computer interaction to model the relationship between users and their personal assistants. Different kinds of trust are needed: trust in the environment and in the infrastructure (the socio-technical system) including trust in your personal agent and in other mediating agents; trust in the potential partners; trust in the warrantors and authorities (if any). Another growing trend is the use of reputation mechanisms, and in particular the interesting link between trust and reputation. Many computational and theoretical models and approaches to reputation have been developed in the last few years. Trust appears to be foundational for the notion of "agency" and for its defining relation of acting "on behalf of". It is also critical for modelling and supporting groups and teams, organisations, co-ordination, negotiation, with the related trade-off between individual utility and collective interest; or in modelling distributed knowledge and its circulation. In several cases the electronic medium seems to weaken the usual bonds in social control, and the habit or disposition to cheat grows stronger. In experiments of cooperation supported by computers it has been found that people are more leaning to defeat than in face-to-face interaction, and a preliminary direct acquaintance reduces this effect. So, computer technology can even break trust relationships already holding in human organisations and relations, and favor additional problems of deception and trust. PAPER SUBMISSIONS We encourage an interdisciplinary focus of the workshop - although focused on virtual environments and artificial agents - as well as presentations of a wide range of models of deception, fraud, reputation and trust building. Just to mention some examples: AI models, BDI models, cognitive models, game theory, and organizational science theories. Suggested topics include, but are not restricted to, the following. Here "mechanisms" include considerations of architecture, design, and protocols.
Authors can submit an extended abstract (4-5 pages) or a long paper (12 pages). Papers (extended abstracts or long papers) must be sent to Rino Falcone (r.falcone@istc.cnr.it). The preferred mode of submission is as a URL to a pdf file; if that is impossible, the submission can be sent as an email attachment.
