Following the success of previous con- ferences held in Beijing (2012), Chongqing (2013), Shenzhen (2014), Nanchang (2015), Kunming (2016), Dalian (2017), Hohhot (2018), Dunhuang (2019), and Zhengzhou(2020),thisyear’sNLPCCwasheldinQingdao,abeautifulcoastalcityin East China. As a premier international conference on natural language processing and Chinese computing, organized by the CCF-NLP (Technical Committee of Natural Language Processing, China Computer Federation, formerly known as Technical CommitteeofChineseInformation,ChinaComputerFederation),NLPCC2021serves as an important forum for researchers and practitioners from academia, industry, and governmenttosharetheirideas,researchresults,andexperiences,andtopromotetheir research and technical innovations in the fields. Thefieldsofnaturallanguageprocessing(NLP)andChinesecomputing(CC)have boomed in recent years. Following NLPCC’s tradition, we welcomed submissions in ten areas for the main conference: Fundamentals of NLP; Machine Translation and Multilinguality; Machine Learning for NLP; Informtion Extraction and Knowledge Graph;SummarizationandGeneration;QuestionAnswering;DialogueSystems;Social MediaandSentimentAnalysis;NLPApplicationsandTextMining;Multimodalityand Explainability.Onthesubmissiondeadline,wewerethrilledtohavereceivedarecord number of 446 valid submissions to the main conference. After a rigid review process, out of 446 submissions (some of which were with- drawnorrejectedwithoutreviewduetoformatissuesorpolicyviolations),104papers were finally accepted to appear in the main conference, where 89 were written in Englishand15inChinese,resultinginanacceptancerate of23.3%.Amongthem,72 submissions were accepted as oral papers and 32 as poster papers. Specifically, ten papers were nominated by our area chairs for the best paper award. An independent best paper award committee was formed to select the best papers from the shortlist. This proceedings includes only the accepted English papers; the Chinese papers will appear in the ACTA Scientiarum Naturalium Universitatis Pekinensis. In addition to the main proceedings, three papers were accepted to the Student workshop, 22 papers were accepted to the Evaluation workshop, and two papers were accepted to the Explainable AI (XAI) workshop. We were honored to have four internationally renowned keynote speakers—Rada Mihalcea (University of Michigan), Yanchao Bi (Beijing Normal University), Sebas- tian Riedel (University College London and Facebook AI Research), and Graham Neubig(CarnegieMellonUniversity)—sharetheirfindingsonrecentresearchprogress and achievements in natural language processing. Wewouldlike tothank allthepeople who have contributedtoNLPCC2021. First of all, we would like to thank our 20 area chairs for their hard work recruiting reviewers, monitoring the review and discussion processes, and carefully rating and vi Preface recommending submissions. We would like to thank all 432 reviewers for their time andeffortstoreviewthesubmissions.WeareverygratefultoTimBaldwin,Chin-Yew Lin, Kang Liu, Deyi Xiong, and Yue Zhang for their participation in the best paper committee. We are also grateful for the help and support from the general chairs, Tim Baldwin and Jie Tang, and from the organization committee chairs, Zhumin Chen, Pengjie Ren, and Xiaojun Wan. Special thanks go to Yu Hong and Ruifang He, the publication chairs, for their great help. We greatly appreciate all your help! Finally,wewouldliketothankalltheauthorswhosubmittedtheirworktoNLPCC 2021, and thank our sponsors for their contributions to the conference. Without your support, we could not have such a strong conference program. We were happy to see you at NLPCC 2021 in Qingdao and hope you enjoyed the conference!
