Computing least common subsumers in description logics is an important reasoning service useful for a number of applications. As shown in the literature, this reasoning service ca...
A class of interval-based temporal languages for uniformly representing and reasoning about actions and plans is presented. Actions are represented by describing what is true whil...
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...
