Uses common entailment regimes and understands their uses.
Using SPARQL with RDFS and OWL Entailment
This chapter accompanied the lecture on SPARQL with entailment regimes given at the 7th Reasoning Web Summer School in Galway, Ireland, 2011. It first introduces [...]
Updating RDFS ABoxes and TBoxes in SPARQL
Updates in RDF stores have recently been standardized in the SPARQL 1.1 Update specification. However, computing answers entailed by ontologies in triple stores is usually [...]
SPARQL Beyond Subgraph Matching
This paper describes the extension of the Semantic Web query language SPARQL by defining the semantics of SPARQL queries under the entailment regimes of RDF, [...]
SPARQL Query Containment under RDFS Entailment Regime
This research paper addresses the problem of SPARQL query containment, which is defined as determining if the result of one query is included in the [...]
Schema-Agnostic Query Rewriting in SPARQL 1.1
SPARQL 1.1 supports the use of ontologies to enrich query results with logical entailments, and OWL 2 provides a dedicated fragment OWL QL for this [...]
On the Semantics of SPARQL Queries with Optional Matching under Entailment Regimes
This paper studies the semantics of SPARQL queries with optional matching features under entailment regimes. It argues that the normative semantics may lead to answers [...]
Dynamic Querying of Mass-Storage RDF Data with Rule-Based Entailment Regimes?
SPARQL is the W3C standard for querying RDF data, but it mostly provides means for querying simple RDF graphs only, whereas querying with respect to [...]
Foundations of Semantic Web Technologies: SPARQL Entailment Regimes
Slides covering the following topics: SPARQL can now be used with RDF Schema, OWL, and RIF semantics. Entailment Regimes overwrite evaluation of basic graph patterns. [...]
SPARQL 1.1 Entailment Regimes
There are different possible ways of defining a basic graph pattern matching extension for an entailment relation. This document specifies one such way for a [...]
Answering SPARQL Queries over Databases under OWL 2 QL Entailment Regime
This paper presents an extension of the ontology-based data access platform Ontop that supports answering SPARQL queries under the OWL 2 QL direct semantics entailment [...]
