Mapping Political Elites COVID-19 Vaccine Tweets in Brazilian Portuguese, 2020-2022

This codebook summarizes the data collection and coding stages employed in developing the Mapping Political Elites COVID-19 Vaccine Tweets in Brazilian Portuguese dataset for Version 2.0. The dataset provides detailed information about the participation of Brazilian political elites on Twitter/X in discussions on COVID-19 vaccines and vaccination and updates the corpus used by Barberia et al. (2023). This project is part of the work undertaken by our research team in NUPRAM - Nucleo de Política, Redes Sociais e Aprendizado de Máquina or Politics, Social Networks and Machine Learning Research Group. NUPRAM seeks to advance the study of political elite discourse in social media on key policy questions using NLP and supervised machine learning.
