Possibilistic reasoning with partially ordered beliefs
This paper presents the extension of results on reasoning with totally ordered belief bases to the partially ordered case. The idea is to reason from logical bases equipped with a partial order expressing relative certainty and to construct a partially ordered deductive closure. The difficult point lies in the fact that equivalent definitions in the totally ordered case are no longer equivalent...
متن کاملReasoning with partially ordered information in a possibilistic logic framework
In many applications, the reliability relation associated with available information is only partially defined, while most of existing uncertainty frameworks deal with totally ordered pieces of knowledge. Partial pre-orders offer more flexibility than total pre-orders to represent incomplete knowledge. Possibilistic logic, which is an extension of classical logic, deals with totally ordered inf...
متن کاملRevising partially ordered beliefs
This paper deals with the revision of partially ordered beliefs. It proposes a semantic representation of epistemic states by partial preorders on interpretations and a syntactic representation by partially ordered belief bases. Two revision operations, the revision stemming from the history of observations and the possibilistic revision, defined when the epistemic state is represented by a tot...
متن کاملA possibilistic handling of partially ordered information
In standard possibilistic logic, prioritized in formation are encoded by means of weighted knowledge bases. This paper proposes an exten sion of possibilistic logic to deal with partially ordered information which can be viewed as a family of possibilistic knowledge bases. We show that all basic notions of possibilis tic logic have natural counterparts when dealing with partially ordered inf...
متن کاملHandling partially ordered preferences in possibilistic logic - A survey discussion -
This paper advocates possibilistic logic with partially ordered priority weights as a powerful representation format for handling preferences. An important benefit of such a logical setting is the ability to check the consistency of the specified preferences. We recall how Qualitative Choice Logic statements (and related ones), as well as CP-nets preferences can be represented in this framework...
