Topic Modeling With Topological Data Analysis (2022.emnlp-main)
Copied to clipboard
| Challenge: | Recent topic modelling approaches that use clustering on word, token or document embeddings can ex-tract coherent topics. |
| Approach: | They propose an unsupervised topic mod-elling method which uses TopologicalData Analysis to extract a topologicalskeleton of the manifold upon which word embeddings lie. |
| Outcome: | The proposed method performs on par with a baseline and can construct a network of coherent topics with meaningful relationships between them. |
