16th Extended Semantic Web Conference (ESWC 2019)
Mobile reasoners play a pivotal role in the so-called Semantic Web of Things. While several tools exist for the Android platform, iOS has been neglected so far. This is due to architectural differences and unavailability of OWL manipulation libraries, which make porting existing engines harder. This paper presents Mini-ME Swift, the first Description Logics reasoner for iOS. It implements standard (Subsumption, Satisfiability, Classification, Consistency) and non-standard (Abduction, Contraction, Covering, Difference) inference tasks in an OWL 2 language fragment. Peculiarities and optimization are discussed and performance results are presented, comparing Mini-ME Swift with other state-of-the-art OWL reasoners.
