Introduction
ELK is a reasoner for OWL 2 ontologies that currently supports a part of the OWL EL ontology language.
The goal of ELK is to provide a very fast reasoning engine for OWL EL. Currently, the supported OWL features and reasoning tasks are still limited (but already sufficient for important ontologies such as SNOMED CT). The aim of the project is to complete the implementation for all OWL EL features and relevant reasoning functions (e.g. for unrestricted use in Protégé) – but this will be done step-by-step so as to ensure top performance of each new feature.
For further information, please see the navigation items on the left.
ELK is currently under heavy development and we welcome feedback from users. Bugs and wishes can be reported via the issue list. Note, however, that ELK supports only some OWL features and reasoning tasks, so there is no need to report bugs related to these known limitations. You can also check the latest nightly builds to see if your bug has been already fixed.
For further feedback and questions, you are also welcome to contact the authors.
