Classifying the Willingness to Act in Social Media Data: Supervised Machine Learning for U.N. 2030 Agenda

In 2015, the United Nation General Assembly adopted the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals aiming at ending all forms of poverty, fighting inequalities and tackling climate change. We collected data about the 2030 Agenda from May 9th to November 9th, 2018. The aim of this work is to obtain a classification of each tweet in the corpus according to the “Information” - “Action” categories, in order to detect whether a tweet refers to an event or it has only an informative-disclosure purpose. Explicit intention to act or inform had been captured by hand coding of a randomly selected sample of tweets and then the classification had been extended to the whole corpus through a supervised machine learning method.
