Figure 3. Spider plot of TV shows, and topic relevance for each candidate.

In this figure we show two spider plots related to the candidates and two main hashtag categories: TV shows and the main terms used in the political discussion shared by all the candidates. Amongst those we selected the 8 most popular. The number of tweets obtained by each candidate associated with a specific hashtag are reported on a logarithmic scale on the relative axis. Mr. Berlusconi outperforms all the others in the TV show section, while in the other case the concepts and words attached to Mr. Bersani (left-wing party) are not that different from those related to Mr. Monti (moderate party), with the notable exception of the word “lavoro” (employment). In both cases the spider profile of Mr. Grillo is sensibly different from all the others.
