QueryVOWL: Visual Composition of SPARQL Queries
نویسندگان
چکیده
The Disjoint edge en6 sures that the two con6 nected nodes are mapped to different individuals in each resultp With a Union node7 restrictions applied to two or more other nodes can be combined in a disjunctionp The result list for the Union node contains all individ6 uals that are valid for at least one of the linked vari6 able nodesp qn Intersection node com6 bines restric6 tions of all linked nodes in a conjunc6 tionp This can be used to avoid rewiring large parts of the query graph when it is discovered that the restrictions for sev6 eral variable nodes need to be combinedp

Visual Querying of Linked Data with QueryVOWL
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. We aim for a language that is intuitive and easy to use, while remaining flexible and preserving ...
متن کاملSparqlFilterFlow: SPARQL Query Composition for Everyone
SparqlFilterFlow provides a visual interface for the composition of SPARQL queries, in particular SELECT and ASK queries. It is based on the intuitive and empirically well-founded filter/flow model that has been extended to address the unique specifics of SPARQL and RDF. In contrast to related work, no structured text input is required but the queries can be created entirely with graphical elem...
متن کاملA model for visual building SPARQL queries
LODeX is a Semantic Web tool that, leveraging a summarized representation of a LOD source structure (i.e. Schema Summary), helps users explore and query SPARQL endpoints by hiding the complexity of Semantic Web technologies. By leveraging Schema Summary of a LOD source, LODeX guides the user in composing visual queries that are automatically translated in correct SPARQL queries through a SPARQL...
متن کاملA Visual Interface for Building SPARQL Queries in Konduit
This short demo description presents an extension to the Konduit tool for visual programming for the semantic desktop. 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. We hope that this will make it ...
متن کاملSQuaRE: A Visual Support for OBDA Approach
We present SQuaRE, the SPARQL Queries and R2RML mappings Environment which provides a visual approach for creating R2RMLmappings which can be immediately tested by executing SPARQL queries. SQuaRE is a web-based tool with easy to use visual interface that can be applied in the ontology-based data access applications. We describe SQuaRE’s main features, its architecture as well as implementation...
