Preface
Welcome to NLPCC 2021, the tenth CCF International Conference on Natural Lan-
guage Processing and Chinese Computing. 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

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!
