Towards extending and using SPARQL for modular document generation

Faisal Alkhateeb, Sébastien Laborie
2008 Proceeding of the eighth ACM symposium on Document engineering - DocEng '08  
RDF is one of the most used languages for resource description and SPARQL has become its standard query language.  ...  Nonetheless, SPARQL remains limited to generate automatically documents from RDF repositories, as it can be used to construct only RDF documents.  ...  Hence, SPARQL could be used to generate documents. However, the SPARQL CONSTRUCT clause is exclusively limited to use an RDF graph pattern, while one may want to generate XML documents.  ...

2014 Proceedings of the 10th International Conference on Semantic Systems - SEM '14  
To overcome these obstacles, we present a modular and extensible open-source question answering framework.  ...  In addition, developing and evaluating question answering systems remains a very complex task.  ...  Acknowledgments This work has been supported by the ESF and the Free State of Saxony and the FP7 project GeoKnow (GA No. 318159) and by CNPq, under the program Ciências Sem Fronteiras.  ...

On Querying Ontologies with Contextual Logic Programming

Cláudio Fernandes, Nuno Lopes, Salvador Abreu
2007 W3C Web Ontology Language (OWL) Experiences and Directions Workshop (OWLED)  
We describe a system in which Contextual Logic Programming is used as a mediator for knowledge modeled by ontologies.  ...  Our system provides the components required to behave as a SPARQL query engine and, as a result of its Logic Programming heritage, it may also recursively interrogate other ontologies or data repositories  ...  The implemented SPARQL agent currently does not cover the full specification. Although full SPARQL language support is not the intended objective, we are working towards extending it.  ...

SCRY: Extending SPARQL with Custom Data Processing Methods for the Life Sciences

Bas Stringer, Albert Meroño-Peñuela, Sanne Abeln, Frank van Harmelen, Jaap Heringa
2016 Workshop on Semantic Web Applications and Tools for Life Sciences  
We propose an effective framework for extending SPARQL with custom methods should fulfill four key requirements: generality, reusability, interoperability and scalability.  ...  SCRY is a lightweight SPARQL endpoint that interprets parts of basic graph patterns as input for user defined procedures, generating an RDF graph against which the query is resolved on-demand.  ...  Another take on extending SPARQL is OGC GeoSPARQL, which "defines a vocabulary for representing geospatial data in RDF, and defines an extension to the SPARQL query language for processing geospatial data  ...

Semantic Query Languages for Knowledge-Based Web Services in a Construction Context

Jeroen Maurits Werbrouck, Madhumitha Senthilvel, Jakob Beetz, Pierre Bourreau, Léon van Berlo
2018 Intelligent Computing in Engineering and Architecture  
In order to combine these into a network of interlinked applications and datastores, an agreed-upon mechanism for automatic communication and data retrieval needs to be used.  ...  Apart from the W3C standard SPARQL, often considered too high a threshold for developers to implement, there are some recent GraphQL-based solutions that simplify the querying process and its implementation  ...  agreement No 820773 and the UGent Special Research Fund (BOF).  ...

We showcase WYSIWYQ with a proof-of-concept prototype implemented on top of the Linked Data Reactor framework and grlc APIs for SPARQL queries.  ...  Nonetheless, and contrarily to the WYSI-WYG approach where users are enabled to switch between the source code and the UI, there is no alternative in Linked Data browsing UIs to generate the browsing UI  ...  Acknowledgments This work was supported by a grant from the European Union's 7th Framework Programme provided for the project RISIS (GA no. 313082).  ...

Linkset–based Data Integration System for LOD Space
Система интеграции данных на основе наборов RDF-связей пространства Linked Open Data

Konstantin Kuznetcov
2012 Proceedings of the Institute for System Programming of RAS  
Proposed system uses concept of RDF identity links to interlink heterogeneous local data sources and integrate them into global data space.  ...  In case of RDF document these triples will be merged into resulting RDF/XML document and returned to client. In other case the triples will be published as HTML+RDFa document generated from template.  ...  These templates can be specified in general form and then redefined for specific classes.  ...

Towards Capturing Contextual Semantic Information About Statements in Web Tables

Felipe Quécole, Romão Martines, José M. Giménez-García, Harsh Thakkar
2018 International Semantic Web Conference  
We explore how this contextual information is represented in tables, and relate it to previous classifications of web tables, and how to encode it in RDF using different approaches.  ...  Hence, we need to use contextualized knowledge graphs to represent the information of the tables.  ...  SPARQL-Generate includes three new clauses: -source clause: used to bind variables to documents -iterator clause: used to extract bits of information from the documents -generate clause: extends the existing  ...
