PyFin-sentiment: Towards a machine-learning-based model for deriving sentiment from financial tweets
International Journal of Information Management Data Insights, 2023 Responding to the poor performance of generic automated sentiment analysis solutions on domain-specific texts, we collect a dataset of 10,000 tweets discussing the topics of finance and investing. We manually assign each tweet its market sentiment, i.e.,
