چکیده

In this paper, we introduce an alternative approach to reasoning about action. The approach provides a solution to the frame and the ramification problem in a uniform manner. The approach involves keeping a (syntax-based) model of the world that is updated when actions are performed. Our approach is similar to the STRIPS system in which formulas are deleted and added as effects of an action. The presented framework however does not suffer from STRIPS’ limitations in expressivity.

Iterated Belief Change Due to Actions and Observations

In action domains where agents may have erroneous beliefs, reasoning about the effects of actions involves reasoning about belief change. In this paper, we use a transition system approach to reason about the evolution of an agent’s beliefs as actions are executed. Some actions cause an agent to perform belief revision while others cause an agent to perform belief update, but the interaction be...

Belief Update Revisited

Although many papers about belief update have been written, its precise scope still remains unclear. In this paper we aim at identifying this scope, and we show that belief update is a specific case of feedback-free action progression. This strong connection with the field of reasoning about action leads us to reconsider belief update and investigate new issues, especially reverse update, which...

An Event-Based Abductive Model of Update

The Katsuno and Mendelzon theory of belief update has been proposed as a reasonable model for revising beliefs about a changing world. However, the semantics of update relies on information which is not readily available. We describe an alternative semantical view of update in which observations are incorporated into a belief set by: a) explaining the observation in terms of a set of plausible ...

Knowledge Assimilation in Domains of Actions: A Possible Causes Approach

One major problem in the process of knowledge assimilation is how to deal with inconsistency of new knowledge and the existing knowledge base. In this paper we present a formal, provably correct and yet computational methodology for assimilation of new knowledge into knowledge bases about actions and changes based on the slogan: What is believed is what is explained. Technically, we employ Gelf...

Abduction to Plausible Causes: An Event-Based model of Belief Update

The Katsuno and Mendelzon (KM) theory of belief update has been proposed as a reasonable model for revising beliefs about a changing world. However, the semantics of update relies on information which is not readily available. We describe an alternative semantical view of update in which observations are incorporated into a belief set by: a) explaining the observation in terms of a set of plaus...
