Studying Taxonomy Enrichment on Diachronic WordNet Versions (2020.coling-main)
Copied to clipboard
| Challenge: | Ontologies, taxonomies and thesauri are used in many NLP tasks but are often not maintained. |
| Approach: | They propose methods for taxonomy enrichment in a resource-poor setting . they also create novel datasets for training and evaluating taxonomies . |
| Outcome: | The proposed methods are applicable to English and Russian datasets and can be used in other languages. |

Viktoriia Chekalina, Alexander Bondarenko, Chris Biemann, Meriem Beloucif, Varvara Logacheva, Alexander Panchenko
| Challenge: | Comparative QA is a challenging task since it requires collecting evidence from many different sources. |
| Approach: | They propose a natural language interface for comparative QA that can be used in personal assistants, chatbots, and similar NLP devices. |
| Outcome: | The proposed system can be used in personal assistants, chatbots, and similar NLP devices. |

Nikita Martynov, Irina Krotova, Varvara Logacheva, Alexander Panchenko, Olga Kozlova, Nikita Semenov
| Challenge: | Existing datasets for paraphrase identification lack challenging sentence pairs with high word overlap. |
| Approach: | They propose to use a dataset for Russian paraphrase detection that includes examples from PAWS translated to the Russian language and manually annotated by native speakers. |
| Outcome: | The proposed model performs well on both datasets while maintaining accuracy on the ParaPhraser benchmark. |
Text Detoxification using Large Pre-trained Neural Models (2021.emnlp-main)

David Dale, Anton Voronov, Daryna Dementieva, Varvara Logacheva, Olga Kozlova, Nikita Semenov, Alexander Panchenko
| Challenge: | Existing studies on text detoxification cast this task as style transfer . text detox requires better preservation of the original meaning, authors argue . |
| Approach: | They propose two unsupervised methods for eliminating toxicity in text . they use a paraphraser guided by style-trained language models to keep the text content . |
| Outcome: | The proposed methods yield new SOTA results. |
ParaDetox: Detoxification with Parallel Data (2022.acl-long)

Varvara Logacheva, Daryna Dementieva, Sergey Ustyantsev, Daniil Moskovskiy, David Dale, Irina Krotova, Nikita Semenov, Alexander Panchenko
| Challenge: | a pipeline for the collection of parallel data for the detoxification task is available. |
| Approach: | They propose a pipeline for the collection of parallel data for the detoxification task . they collect non-toxic paraphrases for over 10,000 English toxic sentences . |
| Outcome: | The proposed pipeline outperforms state-of-the-art models on both automatic and manual evaluations. |
A large-scale computational study of content preservation measures for text style transfer and paraphrase generation (2022.acl-srw)
Copied to clipboard
| Challenge: | Text style transfer and paraphrases generation are growing areas of NLP . many researchers still use BLEU-like measures to evaluate content preservation . |
| Approach: | They compare 57 different measures based on different principles on 19 annotated datasets . they find that measures relying on cross-encoder models outperform alternative approaches . |
| Outcome: | The proposed methods outperform traditional methods on 19 datasets. |

| Challenge: | Existing methods of disambiguation of word senses are based on knowledge bases, taxonomies, and other externally built resources. |
| Approach: | They propose a method that takes a pre-trained word embedding model and induces a fully-fledged word sense inventory for 158 languages. |
| Outcome: | The proposed model is based on a pre-trained word embedding model and induces a fully-fledged word sense inventory in 158 languages. |
