Inconsistency-tolerant query answering in ontology-based data access
Ontology-based data access (OBDA) is receiving great attention as a new paradigm for managing information systems through semantic technologies. According to this paradigm, a Description Logic ontology provides an abstract and formal representation of the domain of interest to the information system, and is used as a sophisticated schema for accessing the data and formulating queries over them....
متن کاملPractical Query Answering in Data Exchange Under Inconsistency-Tolerant Semantics
Exchange-repair semantics (or, XR-Certain semantics) is a recently proposed inconsistency-tolerant semantics in the context of data exchange. This semantics makes it possible to provide meaningful answers to target queries in cases in which a given source instance cannot be transformed into a target instance satisfying the constraints of the data exchange specification. It is known that computi...
متن کاملNew Inconsistency-Tolerant Semantics for Robust Ontology-Based Data Access
In ontology-based data access (OBDA) [17], an ontology provides an abstract and formal representation of the domain of interest, which is used as a virtual schema when formulating queries over the data. Current research in OBDA mostly focuses on ontology specification languages for which conjunctive query answering is first-order (FO) rewritable. In a nutshell, FO-rewritability means that query...
متن کاملA General Modifier-Based Framework for Inconsistency-Tolerant Query Answering
We propose a general framework for inconsistency-tolerant query answering within existential rule setting. This framework unifies the main semantics proposed by the state of art and introduces new ones based on cardinality and majority principles. It relies on two key notions: modifiers and inference strategies. An inconsistency-tolerant semantics is seen as a composite modifier plus an inferen...
متن کاملA General Framework for Inconsistency-tolerant Query Answering in Datalog +/-
Inconsistency management in knowledge bases is an important problem that has beenstudied for a long time. During the recent years, additional interest in this topic has been sparkedwith the advent of the Semantic Web. In this paper, we study different semantics for query answer-ing in inconsistent Datalog+/– ontologies. Datalog+/– is a family of ontology languages that is inpart...
