NoHR (Nova Hybrid Reasoner) is a plug-in for Protégé that allows its users to query knowledge bases composed of an ontology in OWL 2 EL and a set of Reasoning Rules.
Using a top-down reasoning approach, which means that only the part of the ontology and rules that is relevant for the query is actually evaluated, NoHR combines the capabilities of ELK for OWL 2 EL and the rule engine XSB Prolog to deliver very fast interactive response times.
