Keywords:sentiment analysis, surveys, opinion polls, consumer confidence, political elections, text mining, blogs, social media, twitter
We connect measures of public opinion measured from polls with sentiment measured from text. We analyze several surveys on consumer conﬁdence and political opinion over the 2008 to 2009 period, and ﬁnd they correlate to sentiment word frequencies in contempora- neous Twitter messages. While our results vary across datasets, in several cases the correlations are as high as 80%, and capture important large-scale trends. The re- sults highlight the potential of text streams as a substi- tute and supplement for traditional polling. consumer conﬁdence and political opinion, and can also pre- dict future movements in the polls. We ﬁnd that temporal smoothing is a critically important issue to support a suc- cessful model.
