A Method for Reasoning about other Agents' Beliefs from Observations

Authors: Alexander Nittka and Richard Booth

Published in: Dagstuhl Seminar Proceedings, Volume 7351, Formal Models of Belief Change in Rational Agents (2007)

Abstract
Traditional work in belief revision deals with the question of what an agent should believe upon receiving new information. We will give an overview about what can be concluded about an agent based on an observation of its belief revision behaviour. The observation contains partial information about the revision inputs received by the agent and its beliefs upon receiving them. We will sketch a method for reasoning about past and future beliefs of the agent and predicting which inputs it accepts and rejects. The focus of this talk will be on different degrees of incompleteness of the observation and variants of the general question we are able to deal with.

Beyond the Rational Explanation

Authors: Richard Booth and Alexander Nittka

Published in: Dagstuhl Seminar Proceedings, Volume 5321, Belief Change in Rational Agents: Perspectives from Artificial Intelligence, Philosophy, and Economics (2005)

Abstract
In recent work, we proposed a method of reconstructing an agent's epistemic state from observations of its revision history. These observations contained information of what the agent believed after receiving which input. In this presentation we intend to illustrate an extension of the work - allowing the observations to contain additional information of what the agent did *not* believe after a revision step. We will show that the BR-framework we assumed is only partially satisfactory for handling the extended observations.
