INEGI has generated so far. Also, due to its characteristics, the Mood of the
Tweeterers in Mexico is a unique tool worldwide.
The Mood of the Tweeterers is part of an effort to measure welfare
"beyond GDP" and in particular is linked to the agenda for measuring the
subjective wellbeing, which seeks to extract from individuals information on
how they are doing in life, although in this case it is not about self-reported
wellbeing, as happens with traditional survey generated statistics. Instead, in
this case we are talking about a form of wellbeing that is inferred from the
underlying emotional charge present in the messages published on Twitter.
We are taking advantage from the fact that people expressing themselves
when using Twitter are letting us to know much more than the mere message:
they are allowing us to glimpse into their hearts and minds. In this way, the
evolution of the quotient of positivity allows to visualize how the positive and
negative moods diffuse or become generalized to a greater or lesser extent
among the whole twitting population and how this greater or lesser diffusion
changes from one period to another and from a federative entity (state) to
another. This allows us to take a look at aspects of national reality that acquire
greater relevance to the extent that the use of digital social networks is
extended over the Internet.
With a time series beginning in 2016, the system shows a behavior
consistent with what should be expected for a number of clearly identified
events, such as the results of the US Presidential Elections on November 11,
2016 (negative), the increase in national petrol prices at the beginning of 2017
(negative) and the two large earthquakes of September 2017 (both negative),
the triumph in Soccer of Mexico over Germany in June 2017 (positive) and the
award of "The Form of Water" with the Oscar for the best film of 2018. More
relevant, the Mood of the Tweeterers in Mexico showed its capability to
automatically capture the emotional impact of relevant changes in the
environment with the earthquakes of 8 and 19 September 2017. The first
quake had its epicentre in the southern part of the country, while the epicentre
of the second one was very close to Mexico City. Both affected Mexico City,
but the send one hit harder over the capital of the country. In both cases the
positivity ratio showed sharp declines, expressing the negative emotional
impact of the disasters. The following image shows some of the main dates
that can be identified at the national level with the help of the system of “The
Mood of Tweeterers in Mexico”:
