QLever UI2

QLever UI2 is a web-application which provides an intuitive, graphical way to construct and visualize queries against wikidata. It enables users to dive into the world of knowledgebases, without having to know the SPARQL query language.

QLever UI2 is the bachelor project I did at the Chair of Algorithms and Data Structures of Prof. Dr. Hannah Bast as part of my computer science studies at the Albert-Ludwigs-Universität Freiburg. It was supervised by Prof. Hannah Bast

Demo

You can checkout a hosted instance of qlever-ui2 here. The project documentation can be found here.

Project structure
