  Tutorial: Pellet OWL Reasoner

Pellet is an open-source Java based OWL DL reasoner. It can be used in conjunction with either Jena or OWL API libraries.

Tutorial Details:

You can download Pellet API which provides functionalities to see the species validation, check consistency of ontologies, classify the taxonomy, check entailments and answer a subset of RDQL queries (known as ABox queries in DL terminology). You can also use the online demo which provides most of these functionalities.

Pellet is an OWL DL reasoner based on the tableaux algorithms developed for expressive Description Logics. It supports all the OWL DL constructs including the ones about nominals, namely owl:oneOf and owl:hasValue. It is known that using these constructs with inverse properties causes problems in reasoning. Pellet uses a combination of known algorithms and provides reasoning that is sound and complete for OWL DL without nominals (SHIN(D) in DL terminology) and OWL DL without inverse properties (SHON(D) in DL terminology). It is provably sound but incomplete with respect to all OWL DL constructs (SHION(D) in DL terminology).
