DRTS Parsing with Structure-Aware Encoding and Decoding (2020.acl-main)
Copied to clipboard
| Challenge: | Discourse representation tree structure (DRTS) parsing is a new semantic parser which ignores structural information. |
| Approach: | They propose a structural-aware model to integrate structural information into the model . they use graph attention network (GAT) to exploit structural information for effective modeling . |
| Outcome: | The proposed model can achieve the best performance on a benchmark dataset. |
Revisiting a Pain in the Neck: A Semantic Reasoning Benchmark for Language Models (2026.acl-long)
Copied to clipboard
| Challenge: | Semantic phrases (SP) are lexical combinations whose meanings or usages may not be fully derived from their individual components. |
| Approach: | They propose to consolidate existing multiword expression resources into a unified testbed to assess language models in semantic phrase processing tasks. |
| Outcome: | The evaluation suite covers idiomatic expressions, noun compounds, and verbal constructions. |
