We are happy to announce the release of the new
Reasoner for OWL EL
ELK is a free and open source reasoner for the lightweight
ontology language OWL 2 EL, developed by the University of Oxford
and the University of Ulm. It is based on Java and can be
controlled using the OWL API , Protégé , the Snow Owl
ontology editor , or a basic command line interface. ELK is
available under the Apache License 2.0.
The main new features in ELK 0.3.0 are (the full change list available at ):
* brand new ABox support: class/property assertions, consistency checking,
realization, and instance retrieval for named classes,
* extended OWL support: class disjointness, the bottom class (owl:Nothing),
reflexive object properties,
* substantially improved OWL API and Protege experience
(including GUI-based warning reporting, reasoner termination capability, etc.)
ELK is massively parallel and insanely fast. It can classify the SNOMED CT
ontology with around 300,000 classes in a few seconds on a modern
laptop . It runs on all operating systems that support Java 1.6 or
above. For further details, please see the feature list  and the
online discussion group .
Development of ELK is supported by EPSRC in project "ConDOR". The
project is developed at the University of Oxford and the
University of Ulm.
