本章概述了OWL 2 Web本体语言及其三个易于处理的概要(OWL 2 RL、OWL 2EL和OWL 2QL)的描述逻辑。我们考虑这些描述逻辑的语法和语义以及主要的推理任务和它们的计算复杂性,我们还讨论了在OWL2配置文件中给出的知识库上的合取查询的一阶重写和数据重写的语义基础,并概述了基于本体的数据访问系统Ontop的体系结构。
This chapter gives an overview of the description logics underlying the OWL 2 Web Ontology Language and its three tractable profiles, OWL2 RL, OWL2EL and OWL 2QL. We consider the syntax and semantics of these description logics as well as main reasoning tasks and their computational complexity.We also discuss the semantical foundations for first-order and datalog rewritings of conjunctive queries over knowledge bases given in the OWL2 profiles, and outline the architecture of the ontology-based data access system Ontop.
