Papers with Paraphrase Database
Learning Scalar Adjective Intensity from Paraphrases (D18-1)
Copied to clipboard
| Challenge: | Existing lexical resources do not include the relative intensities of adjectives. |
| Approach: | They propose a method to automatically learn relative intensity relation between scalar adjectives . they use a paraphrase-based method that assumes that a pair of adjectives is "really hot" a similar method is used to infer the polarity of indirect answers to "yes/no" questions . |
| Outcome: | The proposed method improves the quality of systems for ordering sets of scalar adjectives and inferring the polarity of indirect answers to "yes/no" questions. |
Using Paraphrases to Study Properties of Contextual Embeddings (2022.naacl-main)
Copied to clipboard
| Challenge: | Previously, paraphrases have been used to probe whether compositionality is accurately captured by BERT, but we believe they can be used to explore many other questions. |
| Approach: | They propose to use paraphrases as a unique source of data to analyze contextualized embeddings, with a particular focus on BERT. |
| Outcome: | The proposed analysis of paraphrases and paraphrase representations using the Paraphrase Database shows that BERT handles polysemous words, but different representations in many cases. |
Integrating Transformer and Paraphrase Rules for Sentence Simplification (D18-1)
Copied to clipboard
| Challenge: | Current models for sentence simplification adopted ideas from machine translation studies and implicitly learned simplification mapping rules from normal-simple sentence pairs. |
| Approach: | They propose a novel model based on a multi-layer and multi-head attention architecture and two innovative approaches to integrate a paraphrase knowledge base for simplification. |
| Outcome: | The proposed model outperforms state-of-the-art models for sentence simplification . it seeks to select more accurate simplification rules, the authors show . |
A Word-Complexity Lexicon and A Neural Readability Ranking Model for Lexical Simplification (D18-1)
Copied to clipboard
| Challenge: | Current lexical simplification approaches rely on heuristics and corpus level features that do not align with human judgment. |
| Approach: | They propose a human-rated word-complexity lexicon and a neural readability ranking model that uses human ratings to measure the complexity of any given word or phrase. |
| Outcome: | The proposed model performs better than state-of-the-art models for lexical simplification tasks and evaluation datasets. |
