Copied to clipboard
| Challenge: | Recent work on grouping together views about tweets expressing opinions about the same entities has been criticized for their lack of thematic coherence. |
| Approach: | They propose to use a corpus of microblogs representing opinions about the same topics within the same time window to evaluate thematic coherence. |
| Outcome: | The proposed method outperforms surface level metrics, topic model coherence and text generation metrics (TGMs) but is not as reliable as TGMs due to being less sensitive to time windows. |

| Challenge: | Using topic modeling, it is possible to study Latin literature through methods and tools that support distant reading. |
| Approach: | They propose to use topic modeling to investigate thematic distribution of Latin corpus . they train, optimize and compare two neural models to evaluate which performs better . |
| Outcome: | The proposed model is compared with two neural models with a Classical Latin corpus and shows that it is coherent and interpretable. |
