Linked Data Queries as Jigsaw Puzzles: a Visual Interface for SPARQL Based on Blockly Library [link]Paper  doi  abstract   bibtex   
SPARQL is a powerful query language for Semantic Web data sources but it is quite complex to master. The jigsaw puzzle methaphor has been succesfully used in Blockly to teach programming to kids. We discuss its applicability to the problem of building SPARQL queries, through the presentation of a dedicated Blockly-based visual user interface.
