Abstract

This work presents and evaluates a new Portuguese context sensitive lexicon for sentiment analysis. Distinctive composition approaches to produce lexicons from established ones were also tested. The experiments were carried out with the corpus ReLi, composed of opinative texts about books, and with the following sentiment lexicons: Brazilian Portuguese LIWC, Opinion Lexicon, and SentiLex.
