Sans contexte, le mod\u00e8le d&rsquo;IA est perdu, comme un d\u00e9tective sans pistes. Plus vous donnez d&rsquo;informations pertinentes au mod\u00e8le, plus il sera capable de comprendre ce que vous attendez de lui et de g\u00e9n\u00e9rer une r\u00e9ponse ad\u00e9quate. Imaginez que vous demandiez \u00e0 un ami de vous rejoindre \u00e0 un \u00ab\u00a0rendez-vous\u00a0\u00bb.  Sans contexte (date, heure, lieu), il sera incapable de se pr\u00e9parer correctement. La contextualisation, c&rsquo;est donc fournir le <em>qui<\/em>, le <em>quoi<\/em>, le <em>quand<\/em>, le <em>o\u00f9<\/em>, le <em>comment<\/em> et le <em>pourquoi<\/em> \u00e0 votre mod\u00e8le.<\/p>\n<h3>Pourquoi la contextualisation est-elle importante ?<\/h3>\n<p>En prompt engineering, la contextualisation permet d&rsquo;orienter le mod\u00e8le d&rsquo;IA vers la r\u00e9ponse souhait\u00e9e.

Un prompt bien contextualis\u00e9 peut faire la diff\u00e9rence entre une r\u00e9ponse g\u00e9n\u00e9rique et une r\u00e9ponse parfaitement adapt\u00e9e \u00e0 vos besoins.<\/p>\n<h3>Exemples d&rsquo;utilisation de la contextualisation<\/h3>\n<ul>\n<li><strong>Traduction:<\/strong>  Pour traduire \u00ab\u00a0run\u00a0\u00bb en fran\u00e7ais, le contexte est crucial.  \u00ab\u00a0I run every morning\u00a0\u00bb se traduira par \u00ab\u00a0Je cours tous les matins\u00a0\u00bb, tandis que \u00ab\u00a0The play had a long run\u00a0\u00bb se traduira par \u00ab\u00a0La pi\u00e8ce a eu une longue s\u00e9rie.\u00a0\u00bb<\/li>\n<li><strong>G\u00e9n\u00e9ration de texte:<\/strong> Si vous demandez \u00e0 une IA d&rsquo;\u00e9crire une histoire, le contexte (genre, personnages, intrigue) influencera le r\u00e9sultat.<\/li>\n<li><strong>Chatbots:<\/strong>  Un chatbot a besoin de contexte (historique de la conversation) pour r\u00e9pondre de mani\u00e8re coh\u00e9rente.<\/li>\n<\/ul>\n<h3>Termes associ\u00e9s<\/h3>\n<ul id=\"TermesAssocies\">\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Prompt+Engineering\">Prompt Engineering<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Intelligence+Artificielle\">Intelligence Artificielle<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Mod%C3%A8le+de+langage\">Mod\u00e8le de langage<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Apprentissage+automatique\">Apprentissage automatique<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Traitement+du+langage+naturel+%28NLP%29\">Traitement du langage naturel (NLP)<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>En intelligence artificielle et en prompt engineering, la contextualisation est une \u00e9tape essentielle pour obtenir des r\u00e9sultats pertinents.
