This paper introduces a new logical formalism, intended for temporal conceptual modelling, as a natural combination of the well-known description logic DLR and point-based linear ...
We show the expressiveness provided by a Labelled point-based metric model for specifying and reasoning about complex disjunctive temporal constraints. The model allows us to mana...
We consider an extension of the guarded fragment in which one can guard quantiers using the transitive closure of some binary relations. The obtained logic captures the guarded fr...
The complexity of set constraints has been extensively studied over the last years and was often found quite high. At the lower end of expressiveness, there are atomic set constra...
We design minimal temporal description logics that are capable of expressing various aspects of temporal conceptual data models and investigate their computational complexity. We ...
