Within the last few years, data warehousing and knowledge discovery technology has established itself as a key technology for enterprises that wish to improve the quality of the results obtained from data analysis, decision support, and the automatic extraction of knowledge from data.
The 6th International Conference on Data Warehousing and Knowledge Discovery (DaWaK 2004) continued a series of successful conferences dedicated to this topic. Its main objective was to bring together researchers and practitioners to discuss research issues and experience in developing and deploying data warehousing and knowledge discovery systems, applications, and solutions.
The conference focused on the logical and physical design of data warehousing and knowledge discovery systems. The scope of the papers covers the most recent and relevant topics in the areas of data cubes and queries, multidimensional data models, XML data mining, data semantics and clustering, association rules, data mining techniques, data analysis and discovery, query optimization, data cleansing, data warehouse design and maintenance, and applications. These proceedings contain the technical papers selected for presentation at the conference.
We received more than 100 papers, including 12 industrial papers, from over 33 countries, and the program committee finally selected 40 papers. The conference program included an invited talk by Kazuo Iwano, IBM Tokyo Research Lab, Japan.
We would like to thank the DEXA 2004 Workshop General Chairs (Prof. Roland Wagner, Prof. A Min Tjoa) and the Organizing Committee of the 15th International Conference on Database and Expert Systems Applications (DEXA 2004) for their support and their cooperation. Many thanks go to Ms. Gabriela Wagner for providing a great deal of assistance as well as to Mr. Raimund Angleitner-Flotzinger and Mr. Andreas Dreiling for administering the conference management software. We are very indebted to all the Program Committee members and external reviewers who reviewed the papers very carefully and in a timely manner. We would also like to thank all the authors who submitted their papers to DaWaK 2004; they provided us with an excellent technical program.
