Key Points
- The article presents an exploratory workflow for analyzing Covid-19 tweets using topic modeling as a way to uncover latent themes in the text data.
- It applies UMAP to visualize high-dimensional tweet representations in a lower-dimensional space to help interpret topic structure and relationships.
- The analysis further uses DiGraphs (directed graph methods) to model how topics or entities relate in directed ways, enabling network-style insights.
- Overall, the piece focuses on combining multiple techniques (topic modeling, UMAP, and graph analysis) to derive interpretable patterns from social-media content.
