First-Order Rewritability of Temporal Ontology-Mediated Queries

Note, however, that the inability to define temporal in particular streaming data, we design a language of predicates such as Blizzard(x, t) in ontologies leaves the ontology-mediated queries by extending OWL 2 QL burden of encoding them within queries to the user, which and SPARQL with temporal operators, and investigate goes against the OBDA paradigm. Moreover, natural queries rewritability of these queries into two-sorted such as'check if a weather station has been serviced every 24 first-order logic with and PLUS over time.
