Query containment and rewriting using views for regular path queries under constraints
In this paper we consider general path constraints for semistructured databases. Our general constraints do not suffer from the limitations of the path constraints previously stud...

Towards a comprehensive treatment of repetitions, periodicity and temporal constraints in clinical guidelines
Temporal constraints play a fundamental role in clinical guidelines. For example, temporal indeterminacy, constraints about duration, delays between actions, and periodic repetiti...
