Topics as Entity Clusters: Entity-based Topics from Language Models and Graph Neural Networks

no code implementations6 Jan 2023 Manuel V. Loureiro, Steven Derby, Tri Kurniawan Wijaya

We demonstrate that our approach consistently outperforms other state-of-the-art topic models across coherency metrics and find that the explicit knowledge encoded in the graph-based embeddings provides more coherent topics than the implicit knowledge encoded with the contextualized embeddings of language models.
