YASGUI: Not Just Another SPARQL Client [chapter]

Laurens Rietveld, Rinke Hoekstra
2013 Lecture Notes in Computer Science  
This paper introduces YASGUI, a user-friendly SPARQL client.  ...  We compare YASGUI with other SPARQL clients, and show the added value and ease of integrating Web APIs, services, and new technologies such as HTML5.  ...  This paper introduces yet another SPARQL GUI (YASGUI 4 ), a SPARQL client that shows the added value of combining Web 2.0 and Semantic Web technologies [1, 2] for providing a more gentle Linked Data  ...

The YASGUI family of SPARQL clients1

Laurens Rietveld, Rinke Hoekstra, Eero Hyvönen
2016 Semantic Web Journal  
In this paper we present the YASGUI family of SPARQL clients, a continuation of the YASGUI tool introduced more than two years ago.  ...  The YASGUI family of SPARQL clients enables publishers to improve ease of access for their SPARQL endpoints, and gives consumers of Linked Data a robust, feature-rich and user friendly SPARQL editor.  ...  Nonetheless, it was just an expectation: because YASGUI hadn't been around for very long, we could not show that this expectation rang true.  ...

SPARQL Playground: A Block Programming Tool to Experiment with SPARQL

Paolo Bottoni, Miguel Ceriani
2015 International Semantic Web Conference  
This user interface attempts to close the gap between tools for the lay user that do not allow to express complex queries and overtly complex technical tools.  ...  the syntax of SPARQL and the model of the data in the endpoint (vocabularies and semantics).  ...  UIs of the second kind provide interaction with another representation of the query -textual or visual-that is then transformed to SPARQL to be executed.  ...

Enabling text search on SPARQL-endpoints through OSCAR

Ivan Heibi, Silvio Peroni, David Shotton, Alejandra Gonzalez-Beltran
2019 Data Science  
YASGUI does not actually offer the possibility of building the SPARQL query graphically, nor does it translate the SPARQL query in any graphical representation.  ...  The strategy adopted in WDQS is close to that proposed by two other tools: NITELIGHT [17] , a Graphical Tool for Semantic Query Construction, and YASGUI [15] [16] (Yet Another SPARQL GUI).  ...

Getting the Most Out of Wikidata: Semantic Technology Usage in Wikipedia's Knowledge Graph [chapter]

Stanislav Malyshev, Markus Krötzsch, Larry González, Julius Gonsior, Adrian Bielefeldt
2018 Lecture Notes in Computer Science  
A live SPARQL endpoint, regular RDF dumps, and linked data APIs are now forming the backbone of many uses of Wikidata.  ...  Co-occurrence of SPARQL features in percent of total queries per dataset (Join, Filter, Optional, Union, Path, Values, Subquery) organic robotic J F O U P V S I1-I3 I4-I6 I1-I3 I4-I6 (none) 8.18 9.35 19.67  ...  As opposed to general-purpose SPARQL editors such as YASGUI [15] , the interface has been customised for Wikidata to improve its functionality.  ...

BESDUI: A Benchmark for End-User Structured Data User Interfaces [chapter]

Roberto García, Rosa Gil, Juan Manuel Gimeno, Eirik Bakke, David R. Karger
2016 Lecture Notes in Computer Science  
It might be argued that this is in fact the desired outcome, that client applications should hide the complexities of semantic technologies and that the benefits should just be evident server side.  ...  We provide a benchmark not just for semantic-web data exploration, but for structured data more generally.  ...

BioSearch: a semantic search engine for Bio2RDF

Wei Hu, Honglei Qiu, Jiacheng Huang, Michel Dumontier
2017 Database: The Journal of Biological Databases and Curation  
Contributing to user frustrations is that data are not necessarily described using common vocabularies, thereby making it difficult to aggregate results, especially when distributed across multiple SPARQL  ...  However, while these data are accessible through programmatic means, effective user interfaces for non-experts to SPARQL endpoints are few and far between.  ...  Enriching the expressiveness of EASE or using another mediating ontology has not been conducted in the evaluation yet.  ...

SparqlBlocks: Using Blocks to Design Structured Linked Data Queries

Enhancing the Usefulness of Open Governmental Data with Linked Data Viewing Techniques

Erwin Folmer, Wouter Beek, Laurens Rietveld, Stanislav Ronzhin, Rutger Geerling, Davey den Haan
2019 Proceedings of the 52nd Hawaii International Conference on System Sciences   unpublished
We start by observing contemporary (Dutch) Open Data platforms and observe that dataset reuse is not always realized.  ...  A SPARQL result set is retunred to the client. These results can be visualized (e.g. on maps or a diagram). 4.  ...  Cesium is not directly able to interpret the WKT formatted serialisations that are present in SPARQL result sets, but it is easy to transform WKT serialisations into GeoJSON, or another format that is  ...

An ontology-based data integration framework for construction information management

Abiodun Akinyemi, Ming Sun, Alasdair J G Gray
2018 Proceedings of the Institution of Civil Engineers: Management, procurement and law  
To ask questions of this data, SPARQL queries can be easily parsed via open source graphical user interface (GUI) tools like Twinkle (Almendros-Jiménez, Becerra-Terón and Cuzzocrea, 2017) and YASGUI (  ...  Another advantage of the proposed framework is that people having similar work process will not need to start from scratch.  ...

Automated API Discovery, Composition, and Orchestration with Linked Metadata

Diego F. Serrano Suarez
2018
This work presents Linked REST APIs (LRA), a simplified description model, based on SPARQL graph patterns, for capturing the semantics and relationships of Web APIs.  ...  However, the data exchanged by Web APIs do not include a semantic representation to enable machines to automatically interpret and appropriately route it.  ...  One of the additional benefits of representing web services in RDF is the possibility to use an expressive declarative language, such as SPARQL, not just to submit data queries created by end users, but  ...

Last but not least, the present work also shows and analyses the current state of published budgetary data internationally and, in particular, in Austria.  ...  The goal to publish information about budgets of governmental authorities in a reasonable, comprehensive, transparent and open way induces challenges not only with respect to the data itself but also to  ...  Sparql GUI" (YASGUI) 75 .  ...
