PROTON: A Prolog Reasoner for Temporal ONtologies in OWL

摘要

We present PROTON, a reasoner for managing temporal information over OWL ontologies. We adopt the so called 4d-fluent or 4-dimensionalist approach for representing temporal information in ontologies i.e. for time points or intervals and for events that occur in time points or intervals. Also, we propose an extension to the situation calculus in order to encapsulate time. PROTON is implemented using this extension.
