Preface
The 2021 China Conference on Information Retrieval (CCIR 2021), co-organized by
the Chinese Information Processing Society of China (CIPS) and the Chinese
Computer Federation (CCF), was the 27th installment of the conference series. The
conferencewashostedbyDalianUniversityofForeignLanguagesinDalian,Liaoning,
China, during October 29–31, 2021.
The annual CCIR conference serves as the major forum for researchers and prac-
titionersfrombothChinaandotherAsiancountries/regionstosharetheirideas,present
newresearchresults,anddemonstratenewsystemsandtechniquesinthebroadfieldof
informationretrieval(IR).SinceCCIR2017,theconferencehasenjoyedcontributions
spanning the theory and application of IR, both in English and Chinese.
This year we received a total of 124 submissions from both China and other Asian
countries. Each submission was carefully reviewed by at least three domain experts,
and the Program Committee (PC) chairs made the final decisions. We accepted 72,
among which 15 were English papers and 57 were Chinese papers. The final English
program of CCIR 2021 featured 15 papers.
CCIR 2021 included abundant academic activities. Besides keynote speeches
delivered by world-renowned scientists from China and abroad, and traditional paper
presentation sessions and poster sessions, we also hosted a young scientist forum, an
evaluationworkshop,andtutorialsonfrontierresearch topics.Wealsoinvitedauthors
from related international conferences (such as SIGIR and CIKM) to share their
research results as well. CCIR 2021 featured four keynote speeches by James Allen
(UniversityofMassachusettsAmherst),SiWu(PekingUniversity),JunWang(UCL),
and Zhongyuan Wang (Meituan Inc.).
The conference and program chairs of CCIR 2021 extend their sincere gratitude to
all authors and contributors to this year’s conference. We are also grateful to the PC
members for their reviewing effort, which guaranteed that CCIR 2021 could feature a
quality program of original and innovative research in IR. Special thanks go to our
sponsors for their generosity: Meituan Inc., Huawei Inc., and Baidu Inc.
