  Previous work in the social sciences, psychology and linguistics has show
that liars have some control over the content of their stories, however their
underlying state of mind may "leak out" through the way that they tell them. To
the best of our knowledge, no previous systematic effort exists in order to
describe and model deception language for Brazilian Portuguese. To fill this
important gap, we carry out an initial empirical linguistic study on false
statements in Brazilian news. We methodically analyze linguistic features using
a deceptive news corpus, which includes both fake and true news. The results
show that they present substantial lexical, syntactic and semantic variations,
as well as punctuation and emotion distinctions.
