Abstract. Opinion Lexicons are linguistic resources annotated with semantic orientation of terms (positive and negative) and are important for opinion mining tasks. In the literature we see a variety of proposals for the construction of opinion lexicons using different linguistic resources and techniques. In this work, we propose and evaluate the integration of such linguistic resources to create a single lexicon for the Portuguese language. 1.
