Abduction as Belief Revision
We propose a model of abduction based on the revision of the epistemic state of an agent. Explanations must be sufficient to induce belief in the sentence to be explained (for instance, some observation), or ensure its consistency with other beliefs, in a manner that adequately accounts for factual and hypothetical sentences. Our model will generate explanations that nonmonotonically predict an...
متن کاملRelating Abduction and Belief Revision
Abduction deals with the search for explanations to justify a brand new observation (i.e., neither the observation nor its negation can be inferred from the previous information). Given an information set Σ and a observation φ, we look for some γ that, together with Σ, makes φ inferable (some γ that, if known before, would have make us to predict φ). In certain situations, it’s useful to do som...
متن کاملAbduction As Belief Revision: A Model of Preferred Explanations
We propose a natural model of abduction based on the revision of the epistemic state of an agent. We require that explanations be sufficient to induce belief in an observation in a manner that adequately accounts for factual and hypothetical observations. Our model will generate explanations that nonmonotonically predict an observation, thus generalizing most current accounts, which require som...
متن کاملBelief Revision Controlled by Meta-abduction
We describe an abductive reasoning agent that is able to change its mind and appropriately revise previous conclusions when it encounters a reasoning dilemma. Abductive inference (by which we mean “Inference to the Best Explanation”) is an ampliative inferential process; that is, the conclusion goes beyond merely extracting information already present in the premises, perhaps unobviously. Thus,...
متن کاملOntology Revision as Non-Prioritized Belief Revision
Ontology revision is the process of managing an ontology when a new axiom or fact would render it inconsistent. So far, the AGM approach to belief revision has been adapted to work with ontologies. However, when multiple sources are contributing uncertain knowledge about a static domain, an approach that doesn’t give priority to incoming information and allows to recover previously discarded ax...
