Actividad e involucramiento en torno a las cuentas de Twitter de periodistas y noticieros televisivos nacionales en México

In the light of the growing divide between political identities on the internet, news distribution on social networks and the attitude of users towards said news has become a very important subject of study for the social sciences these past few years. This report presents the results of our analysis of formal news accounts activity on Twitter throughout 2017, as well as the interactions that surround them, arranged by account, type of activity and segment of interest. From these results, a few possible indicators are proposed for measuring user involvement, searching for an index that allows us to identify controversies in the discussion of news on Twitter. We conclude that the best way to measure involvement is by cross-graphing the amount of interactions per post and the proportion of retweets to formal interactions. This indicator could facilitate both quantitative and qualitative research on Twitter by identifying moments of high enunciation.
