| Challenge: | Existing approaches to find synonyms from text corpora are distributed and pattern based, but they suffer from low precision and low recall. |
| Approach: | They propose a task of synonym expansion using transitivity and propose auxiliary task to reduce the impact of noisy sentences. |
| Outcome: | The proposed approach reduces the impact of noisy sentences and reduces noise in a real-world dataset. |

SynSetExpan: An Iterative Framework for Joint Entity Set Expansion and Synonym Discovery (2020.emnlp-main)
Copied to clipboard
| Challenge: | Entity set expansion and synonym discovery are two critical NLP tasks that are often performed separately, without exploring their interdependencies. |
| Approach: | They propose a framework that enables two tasks to mutually enhance each other by including popular entities’ infrequent synonyms into the set, which boosts set expansion recall. |
| Outcome: | The proposed framework can be used to enhance two NLP tasks by including popular entities’ infrequent synonyms into the set, which boosts set expansion recall. |
Creating a Verb Synonym Lexicon Based on a Parallel Corpus (L18-1)
Copied to clipboard
| Challenge: | a new lexical resource called CzEngClass is being built to help define synonyms in a bilingual context. |
| Approach: | They propose to group verb senses into bilingual verbal synonym groups and use a parallel dependency corpus to explore semantic 'equivalence' they argue that existence of core argument mappings and adjunct mappings to a common set of semantic roles is a suitable criterion for a reasonable verb synonymy definition . |
| Outcome: | The proposed resource will be available by mid-2018 . |
Using pseudo-senses for improving the extraction of synonyms from word embeddings (P18-2)
Copied to clipboard
| Challenge: | Existing methods for specializing word embeddings rely on external knowledge . we propose a new method that focuses on semantic similarity and synonym extraction without external knowledge. |
| Approach: | They propose a method that exploits pseudo-sense for building several representations for each word and uses these representations to make initial embeddings more generic. |
| Outcome: | The proposed method improves word embeddings without external knowledge and focuses on semantic similarity and synonym extraction. |
