Information Organization and Databases: Foundations of Data Organization provides recent developments of information organization technologies that have become crucial not only for data mining applications and information visualization, but also for treatment of semistructured data, spatio-temporal data and multimedia data that are not necessarily stored in conventional DBMSs. Information Organization and Databases: Foundations of Data Organization presents: semistructured data addressing XML, query languages and integrity constraints, focusing on advanced technologies for organizing web data for effective retrieval; multimedia database organization emphasizing video data organization and data structures for similarity retrieval; technologies for data mining and data warehousing; index organization and efficient query processing issues; spatial data access and indexing; organizing and retrieval of WWW and hypermedia. Information Organization and Databases: Foundations of Data Organization is a resource for database practitioners, database researchers, designers and administrators of multimedia information systems, and graduate-level students in the area of information retrieval and/or databases wishing to keep abreast of advances in the information organization technologies.

Foundations of data organization is a relatively new field of research in comparison to, other branches of science. It is close to twenty years old. In this short life span of this branch of computer science, it has spread to all corners of the world, which is reflected in this book. This book covers new database application areas (databases for advanced applications and CAD/VLSI databases), computational geometry, file allocation & distributed databases, database models (including non traditional database models), database machines, query processing & physical structures for relational databases, besides traditional file organization (hashing, index file organization, mathematical file organization and consecutive retrieval property), in order to identify new trends of database research. The papers in this book originally represent talks given at the International Conference on Foundations of Data Organization, which was held on May 21-24, 1985, in Kyoto, Japan. This conference was held at Kyoto University, and sponsored by the organizing committee of the International Conference on Foundations of Data Organization and the Japan Society for the Promotion of Science. The conference was in cooperation with: ACM SIGMOD, IEEE Computer Society, Information Processing Society of Japan, IBM Research, Kyushu University, Kobe University, IBM Japan, Kyoto Sangyo University and Polish Academy of Sciences. This Conference was the follow-up of the first conference, which was hosted by the Polish Academy of Sciences and held at Warsaw in 1981. The Warsaw conference focused mainly on consecutive retrieval property and it's applications."

Within thelastfewyears,datawarehousingandknowledgediscoverytechnology 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 InternationalConference on Data Warehousing and KnowledgeD- covery (DaWaK 2004) continued a series of successful conferences dedicated to this topic. Its main objective was to bring together researchers and practiti- ers 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 wareho- ing and knowledge discovery systems. The scope of the papers covers the most recent and relevant topics in the areas of data cubes and queries, multidim- sionaldatamodels,XMLdatamining,datasemanticsandclustering,association rules, data mining techniques, data analysis and discovery, query optimization, datacleansing,datawarehousedesignandmaintenance,andapplications.These proceedings contain the technical papers selected for presentation at the conf- ence. We received more than 100 papers, including 12 industrial papers, from over 33 countries, and the program committee ?nally selected 40 papers. The conf- ence 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.

This book constitutes the refereed proceedings of the 5th International Conference on Data Warehousing and Knowledge Discovery, DaWaK 2003, held in Prague, Czech Republic in September 2003.

The 41 revised full papers presented were carefully reviewed and selected from more than 130 submissions. The papers are organized in topical sections on data cubes and queries, multidimensional data models, Web warehousing, change detection, Web mining and association rules, association rules and decision trees, clustering, association rule mining, data analysis and discovery, ontologies and improving data quality, queries and data patterns, improving database query engines, and sampling and vector classification.

This book constitutes the refereed proceedings of the 21st International Conference on Conceptual Modeling, ER 2002, held in Tampere, Finland in October 2002.The 30 revised full papers presented with abstracts of various invited contributions were carefully reviewed and selected from close to 130 submissions. The papers are organized in topical sections on semantics and meta-models, principles of ontology, web environments, theory and methods, methods and tools, applications for practice, applying ontology in conceptual modeling, applying ontology in coneptual modeling, systems and data integration, quality assessment, and XML and object systems.

This book constitutes the thoroughly refereed joint post-proceedings of four international workshops held in conjunction with the 20th International Conference on Conceptual Modeling, ER 2001, held in Yokohama, Japan in November 2001.The 37 revised full papers presented were carefully selected and improved during two rounds of reviewing and revision. In accordance with the respective workshops, the papers are organized in topical sections on conceptual modeling and human, organizational, and social aspects; data semantics in web information systems; conceptual modeling approaches for e-business; and global data modeling.

This book constitutes the refereed proceedings of the 4th International Conference on Data Warehousing and Knowledge Discovery, DaWaK 2002, held in Aix-en-Provence, France, in September 2002.The 32 revised full papers presented were carefully reviewed and selected from more than 100 submissions. The papers are organized in topical sections on association rules, clustering, web mining and security, data mining techniques, data cleansing, applications, data warehouse design, OLAP, and data warehouse maintenance.

This book constitutes the refereed proceedings of the Third International Conference on Data Warehousing and Knowledge Discovery, DaWaK 2001, held in Munich, Germany in September 2001. The 33 revised full papers presented together with one invited paper were carefully reviewed and selected from more than 90 submissions. The papers are organized in topical sections on association rules, mining temporal patterns, data mining techniques, collaborative filtering and Web mining, visualization and matchmaking, development of data warehouses, maintenance of data warehouses, OLAP, and distributed data warehouses.

Advances in Database Technologies(ADT) is a workshopseries designed to p- mote interaction and discussion among researchers and practitioners in speci?c topics related to advanced data modeling and database technologies. The ?rst ADT workshop was held in conjunction with the 17th International Conference on Conceptual Modeling (ER'98) in Singapore. It consisted of three small wo- shops, i.e., the"InternationalWorkshoponDataWarehousingandDataMining" organized by Prof. Sham Navathe and Dr. Mukesh Mohania, the "International Workshop on Mobile Data Access" organized by Prof. Dik Lun Lee, and the "InternationalWorkshopon New DatabaseTechnologiesfor CollaborativeWork Support and Spatio-TemporalData Management" organizedby Prof.Yoshifumi Masunaga. These three small workshops were held simultaneously on 19 and 20 November, and the papers were jointly published in this ADT'98 proceedings. Wewouldliketo thankProf.ShamNavathe, Dr. MukeshMohania, Prof.Dik Lun Lee, Prof. Yoshifumi Masunaga and their program committees for wo- ing together to insure an excellent workshop program. The program co-chair of ER'98 Prof. Tok Wang Ling and his organizing committee members gave o- standing support to the workshops with the local arrangements, registration, publicity, and the preparationof the proceedings.
