S2CTrans: Building a bridge from SPARQL to Cypher [PDF]
arXiv, 2023 In graph data applications, data is primarily maintained using two models: RDF (Resource Description Framework) and property graph. The property graph model is widely adopted by industry, leading to property graph databases generally outperforming RDF databases in graph traversal query performance.

SPARQL extensions with preferences [PDF]
Proceedings of the 31st Annual ACM Symposium on Applied Computing, 2016 The last decade has witnessed an increasing interest in expressing preferences inside database queries. Even though most of the work has been devoted to relational databases, many proposals have also been made in the Semantic Web area in order to query RDF databases in a flexible way.

Information, 2018 In recent years, Web APIs have become a de facto standard for exchanging machine-readable data on the Web. Despite this success, however, they often fail in making resource descriptions interoperable due to the fact that they rely on proprietary ...

SPARQLing constraints for RDF [PDF]
Proceedings of the 11th international conference on Extending database technology Advances in database technology - EDBT '08, 2008 The goal of the Semantic Web is to support semantic interoperability between applications exchanging data on the web. The idea heavily relies on data being made available in machine readable format, using semantic markup languages. In this regard, the W3C has standardized RDF as the basic markup language for the Semantic Web.

On the primitivity of operators in SPARQL [PDF]
Information Processing Letters, 2014 The paper studies the primitivity of the basic operators UNION, AND, OPTIONAL, FILTER, and SELECT, as they are used in the SPARQL query language. The question of whether one operator can be expressed in terms of the other operators is answered in detail. It turns out that only AND is non-primitive.

SGPT: A Generative Approach for SPARQL Query Generation From Natural Language Questions
IEEE Access, 2022 SPARQL query generation from natural language questions is complex because it requires an understanding of both the question and underlying knowledge graph (KG) patterns.

SaGe: Web Preemption for Public SPARQL Query Services [PDF]
Proceedings of the 2019 World Wide Web Conference (WWW'19), 2019 To provide stable and responsive public SPARQL query services, data providers enforce quotas on server usage. Queries which exceed these quotas are interrupted and deliver partial results. Such interruption is not an issue if it is possible to resume queries execution afterward.
