Qu&rsquo;est-ce que NER ?  C&rsquo;est un processus qui identifie et classifie des \u00e9l\u00e9ments textuels nomm\u00e9s, tels que les personnes, les organisations, les lieux, les dates, etc., dans un texte non structur\u00e9.<\/p>\n<h3>Comment fonctionne NER ?<\/h3>\n<p>NER utilise des algorithmes d&rsquo;apprentissage automatique pour analyser le texte et extraire les entit\u00e9s nomm\u00e9es. Imaginez un biblioth\u00e9caire qui classe des livres : NER examine chaque mot et, en fonction du contexte et de ses connaissances pr\u00e9alables, le cat\u00e9gorise.  Par exemple, dans la phrase \u00ab\u00a0Elon Musk a fond\u00e9 SpaceX\u00a0\u00bb, NER identifiera \u00ab\u00a0Elon Musk\u00a0\u00bb comme une personne et \u00ab\u00a0SpaceX\u00a0\u00bb comme une organisation.<\/p>\n<h3>Pourquoi NER est-il important ?<\/h3>\n<p>NER est crucial pour de nombreuses applications, notamment l&rsquo;analyse de sentiment, la recherche d&rsquo;informations et les chatbots.  Il permet aux machines de comprendre le sujet d&rsquo;un texte et d&rsquo;en extraire des informations cl\u00e9s. Par exemple, un chatbot peut utiliser NER pour comprendre la demande d&rsquo;un utilisateur : \u00ab\u00a0Je veux r\u00e9server un vol pour Paris\u00a0\u00bb.  Ici, \u00ab\u00a0Paris\u00a0\u00bb est identifi\u00e9 comme un lieu, permettant au chatbot de proposer des vols appropri\u00e9s.<\/p>\n<h3>Termes associ\u00e9s<\/h3>\n<ul id=\"TermesAssocies\">\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Traitement+Automatique+du+Langage+%28TAL%29\">Traitement Automatique du Langage (TAL)<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Apprentissage+Automatique+%28Machine+Learning%29\">Apprentissage Automatique (Machine Learning)<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Reconnaissance+d%27entit%C3%A9s+nomm%C3%A9es\">Reconnaissance d&rsquo;entit\u00e9s nomm\u00e9es<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>La reconnaissance d&rsquo;entit\u00e9s nomm\u00e9es (NER) est une technique essentielle en traitement automatique du langage (TAL).
