Semantics

Semantics (from Ancient Greek : σημαντικός sēmantikós ) [ 1 ] [ 2 ] is the study of meaning . It focuses on the relation between signifiers , like words , phrases , signs , and symbols , and what they stand for, their denotation . Linguistic semantics is the study of meaning that is used for understanding human expression through language.

SPARQL (pronounced " sparkle ", a recursive acronym for S PARQL P rotocol a nd R DF Q uery L anguage ) is an RDF query language , that is, a query language for databases , able to retrieve and manipulate data stored in Resource Description Framework format. [ 1 ] [ 2 ] It was made a standard by the RDF Data Access Working Group (DAWG) of the World Wide Web Consortium , and is considered as one of the key technologies of the semantic web . On 15 January 2008, SPARQL 1.0 became an official W3C Recommendation. [ 3 ] [ 4 ] SPARQL allows for a query to consist of triple patterns , conjunctions , disjunctions , and optional patterns . [ 5 ]
