Fig 8. Entities with extreme sentiment polarity.

Figs (a) and (b) show the entities that exhibit the highest sentiment polarization during the pre-Referendum and pre-Elections period respectively. Polarization is measured as the difference between the average positive and negative sentiment. The negative sentiment values have higher range in Referendum (from -4 to 0) than in Elections (range from -3 to 0). Sentiment values (y axis) are measured according to the SentiStrength score.
