Lifelong machine learning (LML) is a continuous learning process, in which the knowledge base accumulated from previous tasks will be used to improve future learning tasks having few samples. Since there are a few studies on LML based on deep neural networks for NER, especially in Vietnamese, we propose a lifelong learning model based on deep learning with a CRFs layer, named DeepLML\u2013NER, for NER in Vietnamese texts. DeepLML\u2013NER includes an algorithm to extract the knowledge of \u201cprefix-features\u201d of named entities in previous domains. Then the model uses the knowledge in the knowledge base to solve the current NER task. Preprocessing and model parameter tuning are also investigated to improve the performance. The effect of the model was demonstrated by in-domain and cross-domain experiments, achieving promising results.<\/jats:p>","DOI":"10.1142\/s219688881950026x","type":"journal-article","created":{"date-parts":[[2019,10,1]],"date-time":"2019-10-01T06:29:55Z","timestamp":1569911395000},"page":"471-487","source":"Crossref","is-referenced-by-count":5,"title":["Improving Named Entity Recognition in Vietnamese Texts by a Character-Level Deep Lifelong Learning Model"],"prefix":"10.1142","volume":"06","author":[{"given":"Ngoc-Vu","family":"Nguyen","sequence":"first","affiliation":[{"name":"Department of Information Technology, Ministry of Natural Resources and Environment (MONRE), 10, Ton That Thuyet, Cau Giay, Hanoi, Vietnam"}]},{"given":"Thi-Lan","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Vietnam National University, Hanoi (VNU), University of Engineering and Technology (UET), 144, Xuan Thuy, Cau Giay, Hanoi, Vietnam"}]},{"given":"Cam-Van Nguyen","family":"Thi","sequence":"additional","affiliation":[{"name":"Vietnam National University, Hanoi (VNU), University of Engineering and Technology (UET), 144, Xuan Thuy, Cau Giay, Hanoi, Vietnam"}]},{"given":"Mai-Vu","family":"Tran","sequence":"additional","affiliation":[{"name":"Vietnam National University, Hanoi (VNU), University of Engineering and Technology (UET), 144, Xuan Thuy, Cau Giay, Hanoi, Vietnam"}]},{"given":"Tri-Thanh","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Vietnam National University, Hanoi (VNU), University of Engineering and Technology (UET), 144, Xuan Thuy, Cau Giay, Hanoi, Vietnam"}]},{"given":"Quang-Thuy","family":"Ha","sequence":"additional","affiliation":[{"name":"Vietnam National University, Hanoi (VNU), University of Engineering and Technology (UET), 144, Xuan Thuy, Cau Giay, Hanoi, Vietnam"}]}],"member":"219","published-online":{"date-parts":[[2019,11,6]]},"reference":[{"key":"S219688881950026XBIB001","doi-asserted-by":"publisher","DOI":"10.1162\/tacl_a_00104"},{"key":"S219688881950026XBIB003","doi-asserted-by":"publisher","DOI":"10.18653\/v1\/N16-1030"},{"key":"S219688881950026XBIB005","doi-asserted-by":"publisher","DOI":"10.1109\/CVPR.2015.7298799"},{"key":"S219688881950026XBIB006","series-title":"Synthesis Lectures on Artificial Intelligence and Machine Learning","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-031-01581-6","volume-title":"Lifelong Machine Learning","author":"Chen Z.","year":"2018","edition":"2"},{"key":"S219688881950026XBIB007","volume-title":"AAAI Spring Symp.
