In a multi-agent system, an agents belief base can be modified when that agent receives information from other agents. Here, we study the case when these belief base changes occur in a collaborative multi-agent system ...

Research on the relation between Belief Revision and Argumentation has always been fruitful in both directions: some argumentation formalisms can be used to define belief change operators,and belief change techniques have ...

This work presents a set of change operators that can be defined in a stratied belief base, which is a belief base where the beliefs stored in it are assigned a value and each stratum stores all the beliefs that have the ...

This paper presents a belief revision operator that considers time intervals for modelling norm change in the law. This approach relates techniques from belief revision formalisms and time intervals with temporalised rules ...

The problem of knowledge evolution has received considerable attention over the years. Mainly, the study of the dynamics of knowledge has been addressed in the area of Belief Revision, a field emerging as the convergence ...

In this article we explore multiple change operators, i.e., operators in which the epistemic input is a set of sentences instead of a single sentence. We propose two types of change: prioritized change, in which the input ...

In order to properly model norm change in the law, temporal aspects of legal dynamics must be considered. Since there exist several time-based features of law that should be studied, we discuss two interesting approaches: ...
