A segment of Artificial Intelligence, NLP is dedicated to technologically understanding human language.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/eseg.edu.br\/wp-content\/uploads\/2026\/05\/legacy-inline-aff5743043208844-1.jpg\" style=\"width: 25%;float: left\" data-filename=\"imagem-palestra-pln-4.jpg\" class=\"note-float-left\"><\/p>\n<p>Throughout the lecture, the professor introduced basic concepts such as Corpus and Metadata, DTM and tidytext, as well as briefly presenting different systems used in NLP, such as Bag of Words (which takes into account the words used in a given sample) and Semantic Parsing (which analyzes the semantic structure of the sample text). Based on these concepts, the professor complemented his explanation by conducting a live language processing exercise for the students.<\/p>\n<p>During the demonstration, Vizotto presented processes for applying formulas that recognize which words are most frequently used in fake news and in real news, based on a pre-determined sample. With the information obtained, the professor showed that it is possible to analyze the content of these fake news stories. He commented, however, that programs like this are not yet 100% accurate, especially due to the lack of Portuguese dictionaries used for recognizing these words. The development of these dictionaries in Brazil is still recent, and therefore, there are few available.<\/p>\n<p>The meeting was marked by student participation with questions and comments.<\/p>\n<p style=\"text-align: center\"><img decoding=\"async\" src=\"https:\/\/eseg.edu.br\/wp-content\/uploads\/2026\/05\/legacy-inline-1d0bae358d2106b3-1.jpg\" style=\"width: 50%\" data-filename=\"imagem-palestra-pln.jpg\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Programas de reconhecimento analisam palavras e estruturas mais recorrentes em not\u00edcias falsas &nbsp; No dia 24 de maio de 2022, a ESEG &#8211; Faculdade do Grupo Etapa realizou uma palestra sobre a aplica\u00e7\u00e3o de Processamento de Linguagem Natural no reconhecimento de Fake News, ministrada pelo professor Alexandre Albano Pupo Vizotto, mestre em Economia e com [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":12076,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"tags-de-noticias":[],"categorias-de-noticias":[185],"class_list":["post-11870","noticias","type-noticias","status-publish","has-post-thumbnail","hentry","categorias-de-noticias-graduacao"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.8 -
