. In this paper, we describe our submissions to the TREC Incident Stream (TREC-IS) challenge 2018. We investigated di ff erent machine learning approaches to classify crisis-related tweets into di ff erent information types. We incorporated knowledge graphs as features into this social media analysis, in addition to bag of words, word embeddings, time data, and event-types. Further, we evaluate state-of-the-art classification models on 31 generated features sets. Our TREC-IS re-sults indicate that a model based on combining knowledge graphs (i.e., Babelfy), word embeddings and textual features outperformes classical machine learning models.
