El proyecto, para el que se estableci\u00f3 una duraci\u00f3n estimada de 12 meses, presentaba un enfoque pr\u00e1ctico de algunas de nuestras investigaciones previas sobre t\u00e9cnicas de Procesamiento de Lenguaje Natural (PLN).<\/p>\n<p>Se trataba de realizar un an\u00e1lisis autom\u00e1tico de un conjunto de textos en espa\u00f1ol (en este caso, comentarios en foros de opini\u00f3n) para saber de qu\u00e9 se habla y obtener un resumen de los temas m\u00e1s destacados.
