Interactive ontology revision
When ontological knowledge is acquired automatically, quality control is essential. Which part of the automatically acquired knowledge is appropriate for an application often depends on the context in which the knowledge base or ontology is used. In order to determine relevant and irrelevant or even wrong knowledge, we support the tightest possible quality assurance approach – an exhaustive man...
متن کاملWheat and Chaff - Practically Feasible Interactive Ontology Revision
When ontological knowledge is acquired automatically, quality control is essential. We consider the tightest possible approach – an exhaustive manual inspection of the acquired data. By using automated reasoning, we partially automate the process: after each expert decision, axioms that are entailed by the already approved statements are automatically approved, whereas axioms that would lead to...
متن کاملOntology Revision
Knowledge systems as currently configured are static in their concept sets. As knowledge maintenance becomes more sophisticated, the need to address issues concerning dynamic concept sets will naturally arise. Such dynamics is properly called ontology revision, or in the simpler case, expansion. A number of sub-disciplines in artificial intelligence, philosophy and recursion theory have results...
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...
متن کاملThe Ontology Revision
An ontology consists of a set of concepts, a set of constraints imposing on instances of concepts, and the subsumption relation. It is assumed that an ontology is a tree under the subsumption relation between concepts. To preserve structural properties of ontologies, the ontology revision is not only contracting ontologies by discarding statements inconsistent with a revising statement, but als...
