We would like to present, with great pleasure, the ?rst volume of a new jo- nal, Transactions on Rough Sets. This journal, part of the new journal subline in the Springer-Verlag series Lecture Notes in Computer Science, is devoted to the entire spectrum of rough set related issues, starting from logical and ma- ematical foundations of rough sets, through all aspects of rough set theory and its applications, data mining, knowledge discovery and intelligent information processing, to relations between rough sets and other approaches to uncertainty, vagueness, and incompleteness, such as fuzzy sets, theory of evidence, etc. The ?rst, pioneering papers on rough sets, written by the originator of the idea,ProfessorZdzis lawPawlak,werepublishedintheearly1980s.Weareproud to dedicate this volume to our mentor, Professor Zdzis law Pawlak, who kindly enriched this volume with his contribution on philosophical, logical, and mat- matical foundations of roughset theory. In his paper Professor Pawlakshows all over again the underlying ideas of rough set theory as well as its relations with Bayes' theorem, con?ict analysis, ?ow graphs, decision networks, and decision rules.

As information technologies (IT) become specialized and fragmented, it is easy to lose sight that many topics in IT have common threads and because of this, advances in one sub-discipline may transmit to another. The presentation of results between di?erent sub-disciplines of IT encourages this interchange for the advancement of IT as a whole. Of particular interest is the hybrid approach or combining ideas from one discipline with those of another to achieve a result that is more signi?cant than the sum of the individual parts. Through this hybrid philosophy, a new or common principle can be discovered which has the propensity to propagate throughout this multifaceted discipline. This volume comprises the selection of extended versions of papers that were presentedintheirshortenedformatthe2006InternationalConferenceonHybrid InformationTechnology(http://www.sersc.org/ICHIT2006/).Sixty-four papers out of the 235 that were published in ICHIT 2006 electronic proceedings were deemed suitable for inclusion in this volume, in a selection that was guided by technical quality and relevance to the balance of topics in hybrid information technology. The conference re?ected a change in the thinking of scientists and practitioners,whonowtendtojointheire?ortswithinmultidisciplinaryprojects. As a consequence, the readers may observe that many papers might conceivably be classi?ed into more than one chapter, given their interdisciplinary scope. The contributions in this monograph are clustered into six chapters: Data Analysis, Modeling, and Learning (11 papers); Imaging, Speech, and Complex Data (11 papers); Applications of Arti?cial Intelligence (11 papers); Hybrid, Smart, and UbiquitousSystems(11papers);HardwareandSoftwareEngineering(9papers); as well as Networking andTelecommunications (11 papers).
