Multi-token Mask-filling and Implicit Discourse Relations (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Existing mask-filling methods were ambiguous and ambiguic . a new study extends existing mask-filled methods to a discourse-level task . |
| Approach: | They propose a multi-token mask-filling approach that supports the prediction of multi-tongue connectives in masked positions. |
| Outcome: | The proposed multi-token mask-filling outperforms the single-token approach in recognizing implicit discourse relations. |
Syntactic Preposing and Discourse Relations (2024.eacl-long)
Copied to clipboard
| Challenge: | Existing work on discourse has ignored non-canonical syntax . a mask-filling task shows that preposing can affect discourse-relational senses . |
| Approach: | They propose to use preposing to mark information status and structure discourse flow . they use a mask-filling task to predict when a constituent appears in canonical position . |
| Outcome: | The results show that the top-ranked mask-fillers agree more often with "gold" annotations in the Penn Discourse TreeBank than in the latter case. |
