Why Can’t Discourse Parsing Generalize? A Thorough Investigation of the Impact of Data Diversity (2023.eacl-main)
Copied to clipboard
| Challenge: | Discourse parsing performance is not reliable for high-resource languages such as English . a heterogeneous training regime is critical for stable and generalizable models . |
| Approach: | They investigate the impact of genre diversity on RST parsing stability . they use two largest RST corpora of English with text from multiple genres . |
| Outcome: | The proposed model can generalize to text types unseen during training, but it is not reliable for high-resource languages. |

The Change that Matters in Discourse Parsing: Estimating the Impact of Domain Shift on Parser Error (2022.findings-acl)
Copied to clipboard
| Challenge: | Discourse analysis is very low on texts outside of the training distribution’s coverage, diminishing the practical utility of existing models. |
| Approach: | They propose to use a distribution shift statistic to estimate the error-gap of a discourse model and to use it to estimate it. |
| Outcome: | The proposed model can be estimated via distribution shift but does not correlate with change in the observed error of a classifier (i.e. error-gap). |
