ELK is a free and open source reasoner for the lightweight ontology language OWL 2 EL.
Versions & Compatibility
This section lists available versions of ELK.
If you click on the button below to add a new version of ELK, you will be asked to define a page title for the new version. Please adhere to the naming convention of ELK X.X.X when you define the new page!
ELK is very fast. It can classify the SNOMED CT ontology with around 300,000 classes in less than 4 seconds on a modern laptop (details can be found in a technical report). This is achieved by highly optimized consequence-based reasoning algorithms that can also take advantage of multi-core CPUs.
ELK can be run in all operating systems that support Java 1.6 or above, but early releases do not yet support all features of OWL 2 EL. For further details, please see the online documentation. The ELK reasoner discussion group is available for further discussions.
