Fuzzy Systems and Data Mining (FSDM) is an annual international conference devoted to four main groups of topics: a) fuzzy theory, algorithm and system; b) fuzzy application; c) the interdisciplinary field of fuzzy logic and data mining; and d) data mining. Following the great success of FSDM 2015, held in Shanghai, the second edition in the FSDM series was held in Macau China where experts researchers academics participants from the industry were introduced to the latest advances in the field of Fuzzy Sets and Data Mining. Macau was declared a UNESCO World Heritage Site in 2005 by virtue of its cultural importance. The historic centre of Macau is of particular interest because of its mixture of traditional Chinese and Portuguese cultures. Macau has both Cantonese (a variant of Chinese) and Portuguese as official languages.

This volume contains the papers accepted and presented at the 2nd International Conference on Fuzzy Systems and Data Mining (FSDM 2016), held on 11–14 December 2016 in Macau, China. All papers have been carefully reviewed by programme committee members and reflect the breadth and depth of the research topics which fall within the scope of FSDM. From several hundred submissions, 81 of the most promising and FAIA mainstream-relevant contributions have been selected for inclusion in this volume; they present original ideas, methods or results of general significance supported by clear reasoning and compelling evidence.

FSDM 2016 was also a reference conference, and the conference programme included keynote and invited presentations, oral and poster contributions. The event provided a forum where more than 100 qualified and high-level researchers and experts from over 20 countries, including 4 keynote speakers, gathered to create an important platform for researchers and engineers worldwide to engage in academic communication.

I would like to thank all the keynote and invited speakers and authors for the effort they have put into preparing their contributions to the conference. We would also like to take this opportunity to express our gratitude to those people, especially the program committee members and reviewers, who devoted their time to assessing the papers. It is an honour to continue with the publication of these proceedings in the prestigious series Frontiers in Artificial Intelligence and Applications (FAIA) from IOS Press. Our particular thanks also go to J. Breuker, N. Guarino, J.N. Kok, R. López de Mántaras, J. Liu, R. Mizoguchi, M. Musen, S.K. Pal and N. Zhong, the FAIA series editors, for supporting this conference.

Last but not least, I hope that all our participants have enjoyed their stay in Macau and their time at the Macau University of Science and Technology (M.U.S.T.). We hope you had a magnificent experience in both places.
