An iterative topic model filtering framework for short and noisy user-generated data: analyzing conspiracy theories on twitter

Abstract: Conspiracy theories have seen a rise in popularity in recent years. Spreading quickly through social media, their disruptive effect can lead to a biased public view on policy decisions and events. We present a novel approach for LDA-pre-processing called Iterative Filtering to study such phenomena based on Twitter data. In combination with Hashtag Pooling as an additional pre-processing step, we are able to achieve a coherent framing of the discussion and topics of interest, despite of the inherent noisiness a… Show more

“…However, these techniques are also very popular in the social sciences, with applications such as text analysis of conspiracy theories on Twitter (Kant et al, 2022) or the prediction of economic variables such as stock prices (Thormann et al, 2021). But only recently has attention focused on an integral part of scientific applications: model selection, interpretation and especially model evaluation.One of the focal points of the current research is the attempt to achieve a better explainability of the deep learning models and the associated evaluation of the models.…”
