Ils sont constitu\u00e9s de n\u0153uds repr\u00e9sentant des entit\u00e9s (telles que des individus, des organisations ou des concepts) et de bords d\u00e9finissant les relations entre ces entit\u00e9s. Cette structure en r\u00e9seau permet une analyse de donn\u00e9es sophistiqu\u00e9e, des requ\u00eates complexes et un raisonnement intelligent dans divers domaines, notamment les moteurs de recherche, l&#039;intelligence artificielle, le Web s\u00e9mantique, etc.<\/p>\n<h2>L&#039;histoire de l&#039;origine des graphes de connaissances et sa premi\u00e8re mention<\/h2>\n<p>Le concept des Knowledge Graphs remonte \u00e0 la fin du 20e si\u00e8cle, avec les premi\u00e8res impl\u00e9mentations apparaissant dans le domaine du web s\u00e9mantique et de l\u2019intelligence artificielle. Notamment, le d\u00e9veloppement du projet Cyc par Ramanathan Guha en 1984 \u00e9tait l&#039;un des premiers efforts visant \u00e0 cr\u00e9er une repr\u00e9sentation compr\u00e9hensible par ordinateur de la connaissance humaine.<\/p>\n<p>Le terme \u00ab Knowledge Graph \u00bb lui-m\u00eame est devenu populaire apr\u00e8s que Google a introduit son Knowledge Graph en 2012.
