We consider theories characterized by a set of Ward operators which do not form a closed algebra. We impose the Slavnov–Taylor identity built out of the Ward operators and we derive the acceptable breaking of the algebra and the general form of the classical action. The 1PI generating functional is expressed in terms of the known quantities characterizing the theory and of a nontrivial integrab...

Repairing Learned Ontologies

Though ontology learning can help ontology engineers in creating ontologies more rapidly, it also poses new challenges to them especially in creating coherent, high-quality ontologies. Given that there have been proposed ontology learning approaches which are even supporting the generation of highly expressive schemas, the need for pushing debugging methods for such schemas further also arises....
