We present the design of OPTIMISM, an opinion mining system for detection and classification of opinions about relevant political actors, regarding a particular topic of debate. The system gathers opinion-rich texts from Portuguese social media, which are then classified according to their semantic orientation and intensity. Together with the main design decisions, we present the linguistic resources for sentiment analysis in Portuguese under development and the evaluation plan. Evaluation includes comparing opinion statistics produced by the system against poll data collected purposefully for this evaluation.
