Data for ''Why it is important to consider negative ties when studying polarized debates on Twitter: a signed network analysis of a Dutch cultural controversy on Twitter"

This database provides the data used for a study into the debate on Black Pete ("Zwarte Pete") in the Netherlands from 4th of December 2017 until 7th of May 2019. Due to the sensitive character of this data (relating to political beliefs), we only share tweet-ids and the mention sentiment (positive, negative, ambiguous) expresses towards the mentioned user in each tweet. We derived this sentiment with a fastText machine learning model, which we will not share in line with ethical guidelines. The article with details on the classification will be published in PlosOne.
