Furthermore, our approach also fits with a zero-shot scenario, yielding promising results without using any human-labeled data for the task.<\/jats:p>","DOI":"10.24963\/ijcai.2022\/590","type":"proceedings-article","created":{"date-parts":[[2022,7,16]],"date-time":"2022-07-16T02:55:56Z","timestamp":1657940156000},"page":"4252-4258","source":"Crossref","is-referenced-by-count":13,"title":["Low-Resource NER by Data Augmentation With Prompting"],"prefix":"10.24963","author":[{"given":"Jian","family":"Liu","sequence":"first","affiliation":[{"name":"Beijing Key Lab of Traffic Data Analysis and Mining"},{"name":"Beijing Jiaotong University, School of Computer and Information Technology, China"}]},{"given":"Yufeng","family":"Chen","sequence":"additional","affiliation":[{"name":"Beijing Key Lab of Traffic Data Analysis and Mining"},{"name":"Beijing Jiaotong University, School of Computer and Information Technology, China"}]},{"given":"Jinan","family":"Xu","sequence":"additional","affiliation":[{"name":"Beijing Key Lab of Traffic Data Analysis and Mining"},{"name":"Beijing Jiaotong University, School of Computer and Information Technology, China"}]}],"member":"10584","event":{"name":"Thirty-First International Joint Conference on Artificial Intelligence {IJCAI-22}","theme":"Artificial Intelligence","location":"Vienna, Austria","acronym":"IJCAI-2022","number":"31","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"start":{"date-parts":[[2022,7,23]]},"end":{"date-parts":[[2022,7,29]]}},"container-title":["Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2022,7,18]],"date-time":"2022-07-18T11:10:33Z","timestamp":1658142633000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2022\/590"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2022,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2022\/590","relation":{},"subject":[],"published":{"date-parts":[[2022,7]]}}}
