摘要

Interrogative belief revision is a relatively recent framework for belief revision theory, in which the epistemic state of an agent includes a representation of that agent's research agenda, i.e. the set of questions the agent wants to have answers to. This added structure opens new possibilites for various types of epistemic change that cannot be distinguished in traditional belief revision. In this article I use the so-called 'action model' approach known from the literature on dynamic epistemic logic to provide a unified framework in which we can reason about these various types of epistemic changes. I show how to model some natural examples of epistemic changes involving change of the research agenda in this framework. The action models give rise to a dynamic logic which is proven to be decidable.
