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 or OWL 2 QL (from version 2.0.0 on) 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 and a dedicated direct translation for OWL 2 EL and OWL 2 QL respectively with the rule engine XSB Prolog to deliver very fast interactive response times.
