The overwhelming pace of evolution in technology has made it possible to develop intelligent systems which help users in their dayly life activities. - cordingly, methods of recording, managing and analysing data have evolved from the very simple ?le systems into complex ambient supportive intelligent systems. This book arises as a compilation of methods, techniques and tools c- nected with data related issues: from modelling to analysis. A broad range of approaches such as database self-* techniques for ubiquitous environments, multimedia data, or data driven models will be reviewed. Di?erent areas of applications, in which data models conceptualize nowadays reality, starting from e-learning to electric transformers will be considered. The book is a collection of representative contributions to cover the sp- trum related to data bases, which support decision making and data mining methods as well as conceptualization. Datawarehouse technology and m- eling are presented in the ?rst chapter together with the deep review of datawarehouse techniques for supporting e-learning processes with special emphasis on data cubes, all the tools are considered in the context of imp- mentationofsoftwareapplication.Thesecondchaptercontinueswiththes- ilar technology and deals with the community data warehouse architecture.

This book constitutes the refereed proceedings of the 9th International Conference on Rough Sets and Current Trends in Computing, RSCTC 2014, held in Granada and Madrid, Spain, in July 2014. RSCTC 2014 together with the Conference on Rough Sets and Emerging Intelligent Systems Paradigms (RSEISP 2014) was held as a major part of the 2014 Joint Rough Set Symposium (JRS 2014) The 23 regular and 17 short papers presented were carefully reviewed and selected from 120 submissions. They are organized in topical sections such as fuzzy logic and rough set: tools for imperfect information; fuzzy-rough hybridization; three way decisions and probabilistic rough sets; new trends in formal concept analysis and related methods; fuzzy decision making and consensus; soft computing for learning from data; web information systems and decision making; image processing and intelligent systems.

This volume constitutes the proceedings of the 2nd Atlantic Web Intelligence Conference(AWIC2004).TheconferencewasheldinthecityofCancun,Mexico, a setting that inspired lively discussions andre?ections onopen issues facing the ?eld of Web intelligence. TheAWICconferences havebeenmotivated by advancesinthe ?eld ofart- cialintelligenceandthechallengesfacingtheirapplicationtoWeb-basedsystems. With this second edition, AWIC provided a forum for specialists from di?erent disciplines of computer science to exchange their experiences and ideas in this growing ?eld of research. The selection of papers followed a strict, double-blind refereeing process by a renowned international committee. We received 57 contributions, with ?rst authors from 15 di?erent countries, from which 22 papers were selected to be presented and published in this proceedings volume. We thank all members of the Program Committee for their valuable reviews of the papers. In addition, we were pleased to have as invited speakers Dr. Prabhakar Raghavan, Chief Scientist and Vice President of Emerging Technologies in Verity, Inc. and Consulting Professor of Computer Science at Stanford Univ- sity, and Prof. C. Lee Giles, Davide Reese Professorof the School of Information Sciences and Technology at The Pennsylvania State University. Abstracts of their lectures are included in these proceedings. In putting together this conference, we had the pleasure of working with an outstanding group of people. We thank them all for their hard work on behalf of this conference. In particular we would like to thank Manuel Montes y Gomez, ' Director of the Mexico Research Centre of the Web Intelligence Consortium, Elisa Moran, Marcela Rodr' ?guez, and Jorge Niebla.

This book constitutes the refereed proceedings of the First International Atlantic Web Intelligence Conference, AWIC 2003, held in Madrid, Spain in May 2003. The 32 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 70 submissions. The papers are organized in topical sections on general issues in Web intelligence, Web security, semantic Web, Web authoring and design, Web information retrieval, agents for the Web, and user behavior.
