A Lexicographic Inference for Partially Preordered Belief Bases
Coherence-based approaches are quite popular to reason under inconsistency. Most of them are defined with respect to totally preordered belief bases such as the lexicographic inference which is known to have desirable properties from theoretical, practical and psychological points of view. However, partially preordered belief bases offer much more flexibility to represent efficiently incomplete...
متن کاملAssertional-based Removed Set Revision of DL-LiteR Belief Bases
DL-Lite is a tractable fragment of Description Logics, which provides a powerful framework to compactly encode available knowledge with a low computational complexity of the reasoning process. Belief revision is an important problem that appears in many applications and especially in the semantic web area. This paper investigates the so-called “Removed Sets Revision” for revising DL-Lite knowle...
متن کاملSyntactic Propositional Belief Bases Fusion with Removed Sets
The problem of merging multiple sources information is central in several domains of computer science. In knowledge representation for artificial intelligence, several approaches have been proposed for propositional bases fusion, however, most of them are defined at a semantic level and are untractable. This paper proposes a new syntactic approach of belief bases fusion, called Removed Sets Fus...
متن کاملOn Revision of Partially Specified Convex Probabilistic Belief Bases
We propose a method for an agent to revise its incomplete probabilistic beliefs when a new piece of propositional information is observed. In this work, an agent’s beliefs are represented by a set of probabilistic formulae – a belief base. The method involves determining a representative set of ‘boundary’ probability distributions consistent with the current belief base, revising each of these ...
متن کاملComplexity and Cautiousness Results for Reasoning from Partially Preordered Belief Bases
Partially preordered belief bases are very convenient for an efficient representation of incomplete knowledge. They offer flexibility and avoid to compare unrelated pieces of information. A number of inference relations for reasoning from partially preordered belief bases have been proposed. This paper sheds light on the following approaches: the partial binary lexicographic inference, the comp...
