Universal Semantic Tagging for English and Mandarin Chinese (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing approaches to generating semantic annotations for different languages are attracting more and more interest. |
| Approach: | They propose to extend Universal Semantic Tagging to Mandarin Chinese and evaluate its performance. |
| Outcome: | The proposed scheme is only tested in four Indo–European languages . accuracies are 92.7% and 94.6% for Chinese and English respectively . |
Language Generation via DAG Transduction (P18-1)
Copied to clipboard
| Challenge: | Existing formal frameworks for graph manipulation are underexploited. |
| Approach: | They propose a DAG transducer to perform graph-to-program transformation using a declarative programming language. |
| Outcome: | The proposed transducer achieves a BLEU-4 score of 68.07 for natural language generation from type-logical semantic graphs. |
Exact yet Efficient Graph Parsing, Bi-directional Locality and the Constructivist Hypothesis (2020.acl-main)
Copied to clipboard
| Challenge: | Existing algorithms for graph parsing are exponential or high-degree polynomial w.r.t. grammars, and there are few systems that can parse large but frequent MRs with a realistic, wide-coverage grammar in a reasonable time. |
| Approach: | They propose an exact graph parsing algorithm that exploits locality as terminal edge-adjacency in HRG rules and categorizes a subclass of HRG. |
| Outcome: | The proposed method can parse graphs with a (competence) grammar in a time-efficient manner. |
