En este estudio, examinamos el efecto diacr\u00f3nico de la pandemia COVID-19 en el uso y significado de las palabras a trav\u00e9s de la lente de la teor\u00eda de redes complejas. En concreto, analizamos c\u00f3mo se expresan en Twitter un conjunto de usuarios de forma tal de realizar un seguimiento longitudinal y analizamos c\u00f3mo su uso del lenguaje se vio afectado por la pandemia.<\/p>\n<p>Utilizando el an\u00e1lisis de redes, construimos redes correspondientes a tres a\u00f1os diferentes (2019, 2020, 2021) para representar la relaci\u00f3n entre las palabras utilizadas por los usuarios de Twitter, lo que nos permite rastrear cuantitativamente los cambios sem\u00e1nticos. Nuestros resultados demuestran que se pueden detectar cambios sem\u00e1nticos tanto en la aparici\u00f3n de nuevas comunidades en la red sem\u00e1ntica como en el cambio de la vecindad de palabras espec\u00edficas. Proponemos entonces que el uso de redes complejas puede verse como una nueva metodolog\u00eda \u00fatil para rastrear cambios sem\u00e1nticos producidos en diferentes periodos de tiempo y, en particular, ayudarnos a comprender el impacto de la pandemia en el uso del lenguaje.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>El Mi\u00e9rcoles 27\/03 se realiz\u00f3 la Defensa de Tesis de [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":43,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1270","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-sin-categoria"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.10 -
