Simplicity Level Estimate (SLE): A Learned Reference-Less Metric for Sentence Simplification (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing evaluation metrics conflate simplicity with correlated attributes such as fluency or meaning preservation. |
| Approach: | They propose a new learning evaluation metric that focuses on simplicity outperforming most existing metrics in terms of correlation with human judgements. |
| Outcome: | The proposed metric outperforms most existing metrics in terms of correlation with human judgements. |
Discourse-Based Sentence Splitting (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Sentence splitting is a key component of sentence simplification and has been shown to help human comprehension. |
| Approach: | They propose to use a discourse connective to generate a sentence that is shorter than the input text. |
| Outcome: | The proposed models outperform end-to-end models in learning the various ways of expressing a discourse relation but generate text that is less grammatical. |
Controllable Sentence Simplification via Operation Classification (2022.findings-naacl)
Copied to clipboard
| Challenge: | Sentence simplification involves a sentence being transformed into a simpler version of itself while preserving its core meaning. |
| Approach: | They propose a controllable-simplification model that tailors simplifications to four global operations . they propose to use a dataset to train highly accurate classification systems for these operations based on syntactic or discourse structure . |
| Outcome: | The proposed model outperforms both end-to-end and controllable approaches in sentence simplification tasks. |
Context-Aware Document Simplification (2023.findings-acl)
Copied to clipboard
| Challenge: | Recent work on document simplification has focused on sentence-level inputs but fails to preserve the discourse structure. |
| Approach: | They explore various systems that use document context within the simplification process . they investigate the performance and efficiency tradeoffs of system variants . |
| Outcome: | The proposed approach achieves state-of-the-art even when not relying on plan-guidance. |
Document-Level Planning for Text Simplification (2023.eacl-main)
Copied to clipboard
| Challenge: | Existing work on text simplification is limited to sentence-level inputs . attempts to iteratively apply these approaches fail to preserve discourse structure of document . |
| Approach: | They propose a simplification plan that labels each sentence in the input document while considering both its context and internal structure. |
| Outcome: | The proposed model outperforms baselines on two simplification benchmarks and when used to guide document-level simplification models. |
