News from social media is potentially useful for various stakeholders including aid organizations, news agencies, and individuals. However, social media also contains a vast amount of non-news content. For users to be able to draw on benefits from news reported on social media it is necessary to reliably identify news content and differentiate it from non-news. In this paper, we tackle the challenge of classifying a social post as news or not. To this end, we provide a new manually annotated dataset containing 2,992 tweets from 5 different topical categories. Unlike earlier datasets, it includes postings posted by personal users who do not promote a business or a product and are not affiliated with any organization. We also investigate various baseline systems and evaluate their performance on the newly generated dataset. Our results show that the best classifiers are the SVM and BERT models. 4950 https://doi.org/10.26615/issn.2603-2821.2019_002$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:hbz:464-20211221-140156-2$xR$3Volltext$534 4961 https://duepublico2.uni-due.de/receive/duepublico_mods_00072017 5051 004
