Pellet System Description

The description logic SHOIN (D) has attracted considerable interest as the foundation of the W3C standard Web Ontology Language variant, OWL-DL. Pellet is a sound and complete tableau reasoner for SHOIN (D) and incorporates a number of key features such as conjunctive ABox query, axiom pinpointing, rules, E-connection reasoning, and novel optimizations for nominals. In this paper we summarize Pellet’s features and special capabilities.
