Paula Carvalho (PhD in Linguistics) will discuss the most relevant challenges in mining opinions targeting media personalities, like politicians, in social media (e.g. comments posted by users to online news articles and micro-blogs): http://legislativas.sapo.pt/2011/twitometro
Based on previous experiments, Paula will focus on the aspects concerning the creation of linguistic resources (sentiment lexicons, syntactic-semantic rules and annotated corpora) for detecting polarity in opinionated sentences. In addition, Paula will present some preliminary results on the automatic detection of sarcasm and irony in user-generated content. This talk will take place in the classroom S01, on Thursday 23/02/2012 at 10:30.
