Poss-OWL 2: Possibilistic Extension of OWL 2 for an Uncertain Geographic Ontology

AbstractThe use of ontologies to represent geographical knowledge has received a lot of attention recently. Nevertheless, classical ontol- ogy languages are not able to represent incomplete and uncertain knowledge, which are very important characteristics of several situations in geographic domain. Based on our previous work, we propose a solution for handling uncertainty and for dealing with inconsistency in geographical applications. In this paper, we present an extension of the OWL 2, named Poss-OWL 2, based on our Poss - SROIQ(D) description logic (DL). Then we describe some reflections about the inference system. Illustrative examples, from archaeological domain, are given
