Temporal Description Logic for Ontology-Based Data Access (Extended Version) (1304.5185v2)
Published 18 Apr 2013 in cs.LO and cs.AI
Abstract: Our aim is to investigate ontology-based data access over temporal data with validity time and ontologies capable of temporal conceptual modelling. To this end, we design a temporal description logic, TQL, that extends the standard ontology language OWL 2 QL, provides basic means for temporal conceptual modelling and ensures first-order rewritability of conjunctive queries for suitably defined data instances with validity time.
