State of the art reasoners for expressive description logics, such as those that underpin the OWL ontology language, are typically based on highly optimized implementations of (hyp...
We consider expressive Description Logics (ALCN) allowing for number restrictions on complex roles built with combinations of role constructors. In particular, we are mainly inter...
Sonic1 is the first prototype implementation of non-standard inferences for Description Logics that can be used via a graphical user interface. In addition to that our implementat...
Bipolarity is an important feature of spatial information, involved in the expression of preferences and constraints about spatial positioning or in pairs of opposite spatial relat...
Abstract. While there has been a great deal of work on the development of reasoning algorithms for expressive description logics, in most cases only Tbox reasoning is considered. I...
