Probabilistic Topic Modelling with Transformer Representations

1 code implementation6 Mar 2024 Arik Reuter, Anton Thielmann, Christoph Weisser, Benjamin Säfken, Thomas Kneib

With the rise of transformers in Natural Language Processing, however, several successful models that rely on straightforward clustering approaches in transformer-based embedding spaces have emerged and consolidated the notion of topics as clusters of embedding vectors.

GPTopic: Dynamic and Interactive Topic Representations

no code implementations6 Mar 2024 Arik Reuter, Anton Thielmann, Christoph Weisser, Sebastian Fischer, Benjamin Säfken

Topic modeling seems to be almost synonymous with generating lists of top words to represent topics within large text corpora.

Topics in the Haystack: Extracting and Evaluating Topics beyond Coherence
