A Visual Interface for Building SPARQL Queries in Konduit

Knud Möller, Oszkar Ambrus, Laura Josan, Siegfried Handschuh
2008 International Semantic Web Conference  
Previously, Konduit required users to define filter components by manually specifying a SPARQL CONSTRUCT query.  ...  With the current work presented in this demo, we are exploring ways of building such queries visually, and aiding the use in doing it.  ...  Acknowledgments The work presented in this paper was supported (in part) by the Líon project supported by Science Foundation Ireland under Grant No.  ...

Converging Web and Desktop Data with Konduit

Laura Dragan, Knud Möller, Siegfried Handschuh, Oszkar Ambrus, Sebastian Trüg
2009 Extended Semantic Web Conference  
In this paper we present Konduit, a desktop-based platform for visual scripting with RDF data.  ...  The platform allows to combine data from both web and desktop and integrate it with existing desktop functionality, thus bringing us closer to a convergence of Web and desktop.  ...  Acknowledgements The work presented in this paper was supported (in part) by the Líon project supported by Science Foundation Ireland under Grant No.  ...

SPARQLing: A Graphical Interface for SPARQL

Shima Dastgheib, Daniel Ian McSkimming, Kannan Natarajan, Krys Kochut
2015 International Semantic Web Conference  
SPARQLing presents a graphical SPARQL query builder, which allows users of domain ontologies and RDF datasets formulate queries through visual inspection of classes and properties in the ontology or RDF  ...  The results of the discovery queries are used in the Configuration Module and, finally, the query interface is created and displayed based on the configuration file.  ...  Acknowledgement: Funding for NK from the National Science Foundation (MCB-1149106) is acknowledged.  ...

SparqlFilterFlow: SPARQL Query Composition for Everyone [chapter]

Florian Haag, Steffen Lohmann, Thomas Ertl
2014 Lecture Notes in Computer Science  
SparqlFilterFlow provides a visual interface for the composition of SPARQL queries, in particular SELECT and ASK queries.  ...  SparqlFilterFlow is implemented in C#, supports a large number of SPARQL constructs and can be applied to any SPARQL endpoint.  ...  Since average users cannot be expected to have the necessary skills, visual interfaces are needed that hide the SPARQL syntax and provide graphical support for query building.  ...

Visual SPARQL querying based on extended filter/flow graphs

Florian Haag, Steffen Lohmann, Steffen Bold, Thomas Ertl
2014 Proceedings of the 2014 International Working Conference on Advanced Visual Interfaces - AVI '14  
In order to enable users without this knowledge to query linked data, visual interfaces are required that hide the SPARQL syntax and provide graphical support for query building.  ...  Based on the concept of extended filter/flow graphs, we present a novel approach for visual querying that addresses the unique specifics of SPARQL and RDF.  ...  ACKNOWLEDGMENTS We would like to thank our student research assistants Sukanya Bhowmik and Hao Li for their assistance with the prototype implementation.  ...

Visual Querying of Linked Data with QueryVOWL

Florian Haag, Steffen Lohmann, Stephan Siek, Thomas Ertl
2015 Extended Semantic Web Conference  
In order to enable users without any knowledge of RDF and SPARQL to query Linked Data, visual approaches can be helpful by providing graphical support for query building.  ...  We present QueryVOWL, a visual query language that is based upon the ontology visualization VOWL and defines mappings to SPARQL.  ...  Also related are visual interfaces that query Linked Data as part of the browsing process, for instance, by generating and sending SPARQL queries in the background.  ...

OptiqueVQS: A visual query system over ontologies for industry

Ahmet Soylu, Evgeny Kharlamov, Dmitriy Zheleznyakov, Ernesto Jimenez-Ruiz, Martin Giese, Martin G. Skjæveland, Dag Hovland, Rudolf Schlatte, Sebastian Brandt, Hallstein Lie, Ian Horrocks, Freddy Lecue
2018 Semantic Web Journal  
In all these applications, it is important to provide domain experts with query formulation tools for expressing their information needs in terms of queries over ontologies.  ...  In this work, we present such a tool, OptiqueVQS, which is designed based on our experience with OBDA applications in Statoil and Siemens and on best HCI practices for interdisciplinary engineering environments  ...  Visual query systems (VQS) [21] , such as Rhizomer [15] and Konduit VQB [4] , are based on a system of interactions rather than a visual formalism, and therefore can have a design demanding no or limited  ...

A Structured Semantic Query Interface for Reasoning-Based Search and Retrieval [chapter]

Dimitrios A. Koutsomitropoulos, Ricardo Borillo Domenech, Georgia D. Solomou
2011 Lecture Notes in Computer Science  
In this paper, we propose a structured semantic query interface that helps to construct and submit entailment-based queries in an intuitive way.  ...  a careful elaboration of the query itself, in order to extract the desired results.  ...  In addition, they are usually focused on graphical or visual techniques, like NITELIGHT [19] and Konduit [13] .  ...

Facilitating Casual Users in Interacting with Linked Data through Domain Expertise [chapter]

Cormac Hampson, Owen Conlan
2011 Lecture Notes in Computer Science  
Linked Data use has expanded rapidly in recent years; however there is still a lack of support for casual users to create complex queries over this Web of Data.  ...  Semantic attributes are semantically meaningful terms that encapsulate expert rules encoded in multiple formats, including SPARQL.  ...  This research has been supported by The Irish Research Council for Science, Engineering and Technology: funded by the National Development Plan.  ...

In this paper, the Linked Open Graph, LOG, is presented. It is a web tool for collaborative browsing and navigation on multiple SPARQL entry points.  ...  The LOG tool is free to be used, and it has been adopted, developed and/or improved in multiple projects: such as ECLAP for social media cultural heritage, Sii-Mobility for smart city, and ICARO for cloud  ...  A number of tools for visual definition of SPARQL queries have been proposed, as Konduit [10], NITELIGHT [11] .  ...

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.  ...  In today's highly distributed, multi-platform world, there is a huge potential for creating added value through service coordination.  ...  Additionally, the interface restricts the compositions to valid SPARQL queries, that can be visually inspected for semantic errors, which increases the perceived usability of the tool.  ...
