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...
In the quest for expressive description logics for real-world applications, a powerful combination of constructs has so far eluded practical decision procedures: intersection and ...
This paper presents a method for reasoning about spatial objects and their qualitative spatial relationships. In contrast to existing work, which mainly focusses on reasoning abou...
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...
