Abstract
The present invention is a method and apparatus for safe ontology reasoning. In one embodiment, a method for building safe sub-ontology that includes one or more elements of a given ontology includes designating at least one the elements as a sensitive element, where a sensitive element is an element not to be revealed. The method then designates a safe sub-ontology such that the safe sub-ontology does not include any elements that, alone or in combination, allow inference of a sensitive element, in accordance with one or more given inference rules. In another embodiment, a method for building a potential sub-ontology includes designating at least one of the elements as a sensitive element and including a maximal number of the elements in the potential sub-ontology, wherein the maximal number includes the greatest number of elements that can be revealed, cumulatively, without allowing inference of a sensitive element, in accordance with one or more given inference rules.
