KurzfassungAbstract
The importance of taking individual, potentially conflicting perspectives into account when dealing with knowledge has been widely recognised. Many existing ontology management approaches fully merge knowledge perspectives, which may require weakening in order to maintain consistency; others represent the distinct views in an entirely detached way. As an alternative, we propose Standpoint Logic, a simple, yet versatile generic approach to extend existing KR formalisms by the capability to express domain knowledge relative to diverse, possibly conflicting standpoints, which can be hierarchically organised, combined, and put in relation with each other. As a concrete showcase, this extended abstract introduces the standpoint-enhanced version of the very expressive description logic SROIQbs, which is tightly connected to the W3C-standardised ontology language OWL 2 DL. We report that, by virtue of a “small model property” and using some elaborate encoding tricks, it is possible to establish a polytime translation from standpoint-enhanced SROIQbs into plain SROIQbs. By virtue of this result, existing highly optimised OWL reasoners can be used off the shelf to provide practical reasoning support for ontology languages from the OWL family extended by standpoint modelling.
