Artikis A, Sergot M, Pitt JV, 2007, An Executable Specification of a Formal Argumentation Protocol, Artificial Intelligence Journal, Vol: 171, Pages: 776-804
We present a specification, in the action language C+, of Brewka's reconstruction of a theory of formal disputation originally proposed by Rescher. The focus is on the procedural aspects rather than the adequacy of this particular protocol for the conduct of debate and the resolution of disputes. The specification is structured in three separate levels, covering (i) the physical capabilities of the participant agents, (ii) the rules defining the protocol itself, specifying which actions are ‘proper’ and ‘timely’ according to the protocol and their effects on the protocol state, and (iii) the permissions, prohibitions, and obligations of the agents, and the sanctions and enforcement strategies that deal with non-compliance. Also included is a mechanism by which an agent may object to an action by another participant, and an optional ‘silence implies consent’ principle. Although comparatively simple, Brewka's protocol is thus representative of a wide range of other more complex argumentation and dispute resolution procedures that have been proposed. Finally, we show how the ‘Causal Calculator’ implementation of C+ can be used to animate the specification and to investigate and verify properties of the protocol.

Kamara L, Pitt J, Sergot M, 2005, Towards norm-governed self-organising networks, Pages: 137-148
Ad hoc networks may be viewed as computational systems whose members may fail to, or choose not to, comply with the rules governing participation. From this perspective, there is a need for mechanisms to model, monitor and manage interactions in these networks in order to promote their smooth running and correct operation. We propose a norm-governed approach to satisfy these requirements, comprising an agent architecture with an objective reasoning capacity (allowing agents to reason about normative positions) and a suite of protocols for network management. In this paper, we describe a corresponding system architecture that, if successful, will lead to ad hoc networks capable of demonstrating self-organising behaviour in accordance with external system and normative specifications.
Pitt J, Kamara L, Sergot M, et al., 2005, Formalization of a voting protocol for virtual organizations, Pages: 511-518
A voting protocol for decision-making in virtual organizations is presented. In an agent-based virtual organization the functions of formation, management and dissolution of the organization are passed to software processes. Each phase in this life-cycle requires decision making: An ostensibly fair way for independent agents to make decisions is to take a vote. Accordingly, this paper formalizes a protocol for voting. The emphasis is on characterising the powers, permissions, obligations and even sanctions of the voters, using a norm-governed approach to agent societies. The specification language is the Event Calculus, and its animation is informative with respect to a full implementation. It is wellknown that various types of ad hoc alliance of autonomous entities require voting procedures, and a normative specification of the interactions is therefore beneficial for many aspects of self-organization and self-management.
