  1. POPSTAR Public Opinion and Sentiment Tracking, Analysis and Research Main Goals: The design of an opinion mining system able to harvest texts from web-based conventional media(news items in mainstream media sites) and social media (blogs and Twitter) and to process those texts, recognizing topics and political actors, analyzing relevant linguistic units, and generating indicators of both frequency of mention and polarity (positivity/negativity) of mentions to political actors and economic policies across sources, types of sources, and across time. The statistical analysis of the relationship between the previous indicators both among themselves and with public opinion data collected by polls and surveys, testing hypotheses about the directionality of the relationship between conventional media and social media contents, as well as their relationship with mass public opinion. http://dmir.inesc-id.pt/popstar This work is supported by Fundaçãopara a Ciência e Tecnologia (FCT), through the financial support of the POPSTAR project (PTDC/CPJ-CPO/116888/2010)
