Temporal Description Logic for Ontology-Based Data Access.
IJCAI '13: Proceedings of the Twenty-Third international joint conference on Artificial Intelligence（2013）
摘要
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 OWL2QL, provides basic means for temporal conceptual modelling and ensures first-order rewritability of conjunctive queries for suitably defined data instances with validity time.
