Rough Sets and Current Trends in Computing
Thisvolumecontainsthepapersselectedforpresentationatthe5thInternational Conference on Rough Sets and Current Trends in Computing (RSCTC 2006) held in Kobe, Japan, November 6–8, 2006. There were 332 online submissions to RSCTC 2006 as well as two keynote papers, three plenary papers and two commemorative papers. Each submitted paper was reviewed by two or three referees. After a rigorous review process, the three PC chairs checked all the referees’ comments and reviewed the papers again. As a result, 91 papers were selected for publication in this volume. The acceptance rate was only 27. 4%. RSCTCisanoutgrowthofaseriesofannualInternationalWorkshopsdevoted to the subject of roughsets, started in Poznan, Polandin 1992,and then held in Canada, the USA, Japan and China (RSKD, RSSC, RSFDGrC, RSGrC series). The?rstRSCTCconferencewasheldinWarsaw,Polandin1998. Itwasfollowed by successful RSCTC conferences in Ban?, Canada (2000), in Malvern, USA (2002) and in Uppsala, Sweden (2004). Rough set theory, proposed by Zdzis law Pawlak in 1982, has been attra- ing researchers and practitioners in various ?elds of science and technology. The interest in rough set theory and applications has been remarkable since the - ginning, and it is still growing. The ingenious concepts of rough sets have been a base for original developments in both theoretical research, including logics, algebra and topology, and applied research,including knowledge discovery, data mining, decision theory, arti?cial intelligence and approximate reasoning. The latter led to many real life applications in diversi?ed areas such as medicine, bioinformatics, economy, ?nance, political analysis, chemistry, engineering, - vironment, and even art and culture.
