Using SPARQL – The Practitioners’ Viewpoint [PDF]
, 2018 A number of studies have analyzed SPARQL log data to draw conclusions about how SPARQL is being used. To complement this work, a survey of SPARQL users has been undertaken. Whilst confirming some of the conclusions of the previous studies, the current work is able to provide additional insight into how users create SPARQL queries, the difficulties they

Modern Baselines for SPARQL Semantic Parsing [PDF]
Annual International ACM SIGIR Conference on Research and Development in Information Retrieval, 2022 In this work, we focus on the task of generating SPARQL queries from natural language questions, which can then be executed on Knowledge Graphs (KGs). We assume that gold entity and relations have been provided, and the remaining task is to arrange them ...

Facade-X: an opinionated approach to SPARQL anything [PDF]
Studies on the Semantic Web, 2021 The Semantic Web research community understood since its beginning how crucial it is to equip practitioners with methods to transform non-RDF resources into RDF. Proposals focus on either engineering content transformations or accessing non-RDF resources

Proceedings of the 18th international conference on World wide web, 2009 C-SPARQL is an extension of SPARQL to support continuous queries, registered and continuously executed over RDF data streams, considering windows of such streams. Supporting streams in RDF format guarantees interoperability and opens up important applications, in which reasoners can deal with knowledge that evolves over time.
