Questions tagged [pellet]

The Pellet reasoner is a Java based reasoning software that performs entailment tasks for OWL ontologies. This reasoner can be used with multiple frameworks such as Apache Jena, OWL-API and Protégé.

The Pellet reasoning software can perform inferencing over OWL 2 ontologies. It can be used stand alone or be integrated via APIs. Integrations with Jena, OWL-API and Protégé are described in Pellet's FAQ.

Questions could be about : - Integration and evolution of Pellet and its forks. - How its work and how it perform against other reasoning system(Hermit, Fact++, KM, Thea, etc...). - Integration with other applications Protege. - How to use a reasoner to get a specific result. - How it should be use, how it should not. - Help students when stuck (but with a something to show).
