Combining multiple prioritized knowledge bases by negotiation
Recently, several belief negotiation models have been introduced to deal with the problem of belief merging. A negotiation model usually consists of two functions: a negotiation function and a weakening function. A negotiation function is defined to choose the weakest sources and these sources will weaken their point of view using a weakening function. However, the currently available belief ne...
متن کاملCombining Multiple Knowledge Bases by Negotiation: A Possibilistic Approach
A negotiation model consists of two functions: a negotiation function and a weakening function. A negotiation function is defined to choose the weakest sources and these sources will weaken their point of view using a weakening function. However, the currently available belief negotiation models are based on classical logic, which make it difficult to define weakening functions. In this paper, ...
متن کاملCombining individually inconsistent prioritized knowledge bases
It is well accepted that inconsistency may exist in a database system or an intelligent information system (Benferhat et al. 1993a; 1993b; 1997b; 1998; Benferhat & Kaci 2003; Elvang-Gøransson & Hunter 1995; Gabbay & Hunter 1991; Lin 1994; Priest et al. 1989; Priest 2001). Inconsistency can either appear in the given knowledge bases or as a result of combination or revision. In this paper, we wi...
متن کاملCombining Multiple Knowledge Bases
AbstmctKnowledge present in multiple knowledge bases might need to be reviewed to make decisions based on the combined knowledge. We define the concept of combining knowledge present in a set of knowledge bases and present algorithms to maximally combine them SQ that the combination is consistent with respect to the integrity constraints associated with the knowledge bases. For this we define t...
متن کاملPrioritized and Non-prioritized Multiple Change on Belief Bases
In this article we explore multiple change operators, that is, 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 set is fully accepted, and symmetric change, in which both the epistemic state and the epistemic input are equally treated. In both kinds of operators we propose a set of p...
