Is Partial Linguistic Information Sufficient for Discourse Connective Disambiguation? A Case Study of Concession (2025.acl-srw)
Copied to clipboard
| Challenge: | Discourse relations are often not linguistically marked, but there are various connectives that explicitly signal discourse relations. |
| Approach: | They analyze linguistic features that play an important role in disambiguation of polysemous connectives in Japanese by performing a neural language model. |
| Outcome: | The proposed model performed well after removal of one of the two arguments that constitute the discourse relation, but significantly degraded disambiguation performance. |
Annotation of Japanese Discourse Relations Focusing on Concessive Inferences (2024.lrec-main)
Copied to clipboard
| Challenge: | concessive discourse relations are crucial for understanding language, and annotation is performed on polysemous conjunctions. |
| Approach: | They present an annotation method for the Japanese conjunctions nagara and tsutsuke, and an annotation for the ambiguous Japanese conjunction tokorode. |
| Outcome: | The annotations for nagara and tsutsuke were performed on Japanese conjunctions and revealed the characteristics of concession that became apparent during annotation. |
