Query Builder System for Resource Description Framework Based Knowledge Stores

According to one embodiment, a computer-implemented method, includes accessing, by a computer system, a knowledge store that stores records structured according to a RDF specification. The method also includes, based on a drag-and-drop selection technique, receiving a first entry in a first query entry field. The first entry is selected from a group comprising one or more of the following: a first class of a plurality of classes, a first predicate of a plurality of predicates, a first instance of a plurality of instances, and a first text entry of a plurality of text entries. The method further includes generating a SPARQL query using at least the first entry. The method further includes transmitting the generated SPARQL query to the knowledge store.
