{"url":"/method/btmpg","slug":"btmpg","name":"BTmPG","full_name":"BTmPG","full_name_withheld":false,"description_markdown":"**BTmPG**, or **Back-Translation guided multi-round Paraphrase Generation**, is a multi-round paraphrase generation method that leverages back-translation to guide paraphrase model during training and generates paraphrases in a multiround process. The model regards paraphrase generation as a monolingual translation task. Given a paraphrase pair $\\left(S\\_{0}, P\\right)$, which $S\\_{0}$ is the original/source sentence and $P$ is the target paraphrase given in the dataset. In the first round generation, we send $S\\_{0}$ into a paraphrase model to generate a paraphrase $S\\_{1}$. In the second round generation, we use the $S\\_{1}$ as the input of the model to generate a new paraphrase $S\\_{2}$. And so forth, in the $i$-th round generation, we send $S\\_{i−1}$ into the paraphrase model to generate $S\\_{i}$.\r\n.","description_state":"present","introduced_year":null,"introduced_by":{"title":null,"paper":null,"first_author":null,"n_authors":0,"url_abs":null,"archive_paper_url":null},"source":{"url":"https://arxiv.org/abs/2109.01862v1","title":"Pushing Paraphrase Away from Original Sentence: A Multi-Round Paraphrase Generation Approach","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"Natural Language Processing","area_id":"natural-language-processing","collection":"Paraphrase Generation Models","url":"/methods/category/paraphrase-generation-models","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":null,"papers_newest_first":[{"paper":"/paper/pushing-paraphrase-away-from-original","title":"Pushing Paraphrase Away from Original Sentence: A Multi-Round Paraphrase Generation Approach","date":"2021-09-04","arxiv_id":"2109.01862","n_code_links":1,"syntology":{"ran":4,"of":4,"unverified":0,"pointer_only":0}}],"papers_shown":1,"tasks":[{"task":"/task/diversity","name":"Diversity","papers":1},{"task":"/task/paraphrase-generation","name":"Paraphrase Generation","papers":1},{"task":"/task/sentence","name":"Sentence","papers":1},{"task":"/task/translation","name":"Translation","papers":1}],"tasks_shown":4,"n_tasks":4,"usage_by_year":[{"year":"2021","papers":1}],"row_source":"embedded","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/btmpg"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
