The BDI model is well accepted as an architecture for representing and realizing rational agents. The beliefs in this model are focused on the representation of beliefs about the world and other agents and are widely independent from the agents intentions. We argue that also the representation of know-how, which captures the beliefs about actions and procedures, has to be taken into account whe...

This paper aims to explore the role of questions in communication in a group of cooperative rational agents. Using epistemic representation of questions proposed in [6] we employ the framework of public announcement logic to explore the flow of information in the process of asking and replying questions in a group. We show that some of the erotetic notions we introduce nicely correspond to the ...

We show through a number of examples how it is possible to express beliefs of agents and communication among agents by employing a rst-order logic language with metalogical facilities. We argue that (i) such a language is suitable to characterise rational agents in diierent application areas, and (ii) the interplay between metalogical reasoning and diierent modalities of communications allows u...

Modelling real world problems using rational agents has been heavily investigated over the past two decades. BDI (Beliefs, Desires, and Intentions) Logic has been widely used to represent and reason about rational agency. However, in the real world, we often have to deal with different levels of confidence in the beliefs we hold, desires we have, and intentions that we commit to. This paper pro...

The global objective of open multiagent systems might be in conflict with individual preferences of rational agents participating in such systems. Addressing this problem, we propose a mechanism able to attach incentives to agent actions such that the global utility of the system is improved. Such incentives are dynamically adjusted to each agent’s preferences by using institutional agents call...

This research explores productive multi-player games as a platform for human-computer agent collaboration. A multiagent perspective is taken to examine the principles of both gameplay and mechanism design for productive games. To engage human players in sustained gameplay, the game agents are designed with the flow and dramatic principles. To ensure productivity, the game mechanism is designed ...

T h e preface paradox strikes us as puzzling because we feel that if a person holds a set of inconsistent beliefs, i.e. beliefs such that at least one of them must be incorrect, then he should give at least one of them up. Equally, if a person’s belief is rational, then he has a right to hold it. Yet the preface example is prima facie a case in which a person holds an inconsistent set of belief...
