X-GTA: The Cross-Topic German Twitter Archive

X-GTA (The Cross Topic German Twitter Archive) comprises an extensive assortment of over two billion German-language Tweets, captured in the period spanning from October 2018 to March 2023. Recognizing the significant role that Twitter has come to play as a data source for scholarly investigations, we initiated this project to aggregate German Tweets without subject restrictions, thereby generating a multifaceted dataset reflecting a broad spectrum of themes. Consequently, X-GTA does not merely facilitate comprehensive analyses of topic discourse on Twitter, but also empowers comparative studies of different themes and their temporal popularity shifts. This article elaborates on the methodologies employed in data collection, generation, management, and data access, and serves as a detailed guide to the information contained in the X-GTA dataset.
