Abstract

Rough Set is a mathematical theory for processing uncertain data and information, which was first described by Professor Pawlak in 1982. The rough set research in China is growing very quickly in recent years. Professor Pawlak helped the development of Chinese rough set community a lot. It is the 10th anniversary of Professor Pawlaks death this year. This paper is a record of the history of the born and growing of Chinese rough set community and a commemoration of Professor Pawlak, our old friend.

Rough Set China Professor Zdzisaw Pawlak

The Born of Chinese Rough Set Community

Rough Set is a mathematical theory for processing uncertain data and information, which was first described by Professor Zdzisaw Pawlak in 1982 [], including China.

The rough set study in China was started in 1990s. The Chinese Rough Set and Soft Computing Society (CRSSC) became a branch of the Chinese Association of Artificial Intelligence (CAAI) in 2003. It has about 800 members now. It becomes the largest national rough set society in the whole world.

I am writing this article to record the history of the born and growing of rough set community in China in the past 20 years, and introduce the great help and support of Professor Pawlak for the born and quick growing of the rough set in China to commemorate the 10 anniversary of his death.

After graduating from the Xian Jiaotong University at the end of 1996, I joined the Chongqing University of Posts and Telecommunications. I read some rough set papers and start to learn and study rough set based knowledge acquisition from 1997. This is my first time to know the name of rough set theory and Professor Pawlak. I got my 1st NSFC research grant Rough Set Based Automatic Knowledge Acquisition Technology and Its Application in 1998, and visited Professor Yiyu Yao at University of Regina for about 1 month in 1999. Professor Yiyu Yao introduced a lot about rough set theory and Professor Pawlak to me when I was in Regina. After coming back at Chongqing, I started to set up a Chinese rough set society and initialize a Chinese rough set workshop/conference. Professor Qing Liu, a key senior rough set researcher in China, planed it together with me. We sent an email to Professor Pawlak to invite him to visit Chongqing, attend the 1st Chinese Conference on Rough Sets and Soft Computing (CRSSC2001) and give a keynote talk. We received his positive response immediately.

The First Chinese Conference on Rough Set and Soft Computing (CRSSC2001) [ is the CRSSC2001 proceeding which is published as a special issue of the Journal of Computer Science. The Chongqing city government thought highly of the conference and supported it very much. Some high-ranking officials of the Chongqing government such as Professor Ruihua Dou, the vice Chairman of the Chongqing Political Consultation Committee and the former vice mayor of Chongqing, Professor Chunlin Zhai, the vice President of the Chongqing Association for Science and Technology, Professor Yuhui Qiu, the President of Southwest Normal University and the Chairman of Chongqing Computer Society, and Professor Neng Nie, the President of Chongqing University of Posts and Telecommunications, attended the conference. During this conference, I proposed a plan for setting up a Chinese rough set society. Many CRSSC2001 attendees expressed their interests of joining the society. Professor Pawlak stayed in Chongqing 4 days. He discussed with Chinese researchers about rough set related researches and introduced the development of rough set theory. He expressed his desire to support the development of rough set theory in China. Thus, we can say that Professor Pawlak witnessed and contributed to the born of Chinese rough set community.

Rough Set Conferences Organized in China

Since 2001, the Chinese conference on rough set and soft computing (CRSSC) is held every year. It is held together with the Chinese conference on web intelligence (CWI) and Chinese conference on granular computing (CGrC) every year since 2007. Until now, it has been held 15 times in many different cities in China. Table is a list of the national rough set conferences in China. These conferences pushed the quick development of rough set research in China.

CRSSC2001	Chongqing
CRSSC2002	Suzhou	About 150
CRSSC2003	Chongqing
CRSSC2004	Zhoushan	Over 100
CRSSC2005	Anshan

CRSSC-CWI-CGrC2010	Chongqing
CRSSC-CWI-CGrC2011	Nanjing
CRSSC-CWI-CGrC2012	Hefei	About 180
CRSSC-CWI-CGrC2013	Zhangzhou
CRSSC-CWI-CGrC2014	Kunming
CRSSC-CWI-CGrC2015	Tangshan	Over 300

Note (1) CRSSC is the Chinese conference on rough set and soft computing

(2) CRSSC-CWI-CGrC the joint conference of Chinese conference on rough set and soft computing, Chinese conference on web intelligence, and Chinese conference on granular computing (CGrC)

Professor Pawlak also helped Chinese researchers to join the international rough set community. With his help and support, the 9th International Conference on Rough Sets, Fuzzy Sets, Data Mining and Granular Computing (RSFDGrC2003) [] and booked his ticket for attending the conference. Unfortunately, SARS happened in the whole world in 2003. RSFDGrC2003 had to be postponed to October, 2003. Professor Pawlak changed his trip plan and failed to attend the conference in October due to his health reasons at last.
