The refereed proceedings of the 15th International Conference on Advanced Information Systems Engineering, CaiSE 2003, held in Klagenfurt, Austria in June 2003. The 45 revised full papers presented together with 3 invited contributions were carefully reviewed and selected from 219 submissions. The papers are organized in topical sections on XML, methods and models for information systems, UML, Internet business and social modeling, peer-to-peer systems, ontology-based methods, advanced design of information systems, knowledge, knowledge management, Web services, data warehouses, electronic agreements and workflow, requirements engineering, metrics and method engineering, and agent technologies and advanced environments.

This book constitutes the proceedings of the 18th International Symposium on String Processing and Information Retrieval, SPIRE 2011, held in Pisa, Italy, in October 2011. The 30 long and 10 short papers together with 1 keynote presented were carefully reviewed and selected from 102 submissions. The papers are structured in topical sections on introduction to web retrieval, sequence learning, computational geography, space-efficient data structures, algorithmic analysis of biological data, compression, text and algorithms.

This book constitutes the refereed proceedings of the 7th International Symposium on Web and Wireless Geographical Information Systems, W2GIS 2007, held in Cardiff, UK, in November 2007. The 21 revised full papers presented were carefully reviewed and selected from 45 submissions. The papers provide an up-to-date review of advances in recent development of Web and wireless geographical information systems, and address a broad range of issues like conceptual and logical models for W2GIS.

This book constitutes the refereed proceedings of the 9th International Conference on Database Theory, ICDT 2002, held in Siena, Italy in January 2002. The 26 revised full papers presented together with 3 invited articles were carefully reviewed and selected from 92 submissions. The papers are organized in topical sections on reasoning about XML schemas and queries, aggregate queries, query evaluation, query rewriting and reformulation, semistructured versus structured data, query containment, consistency and incompleteness, and data structures.

This book constitutes the thoroughly refereed postproceedings of the First International Workshop on Semantic Web Services and Web Process Composition, SWSWPC 2004, held in San Diego, CA, USA in July 2004. The 9 revised full papers presented together with an introduction by the volume editors, a panel summary and the extended abstract of an invited talk were carefully selected during two rounds of reviewing and improvement. Web services and Web processes promise to ease several current Web infrastructure challenges, such as the integration of data, applications and processes. Web services are truly platform independent and allow the development of distributed loosely coupled applications, a key characteristic for the success of dynamic processes.

On behalf of the Organizing Committee, we would like to welcome you to the proccedings of the 23rd International Conference on Conceptual Modeling (ER 2004). This conference provided an international forum for technical discussion on conceptual modeling of information systems among researchers, developers and users. This was the third time that this conference was held in Asia; the?rst time was in Singapore in 1998 and the second time was in Yokohama, Japan in 2001. China is the third largest nation with the largest population in the world. Shanghai, the largest city in China and a great metropolis, famous in Asia and throughout the world, is therefore a most appropriate location to host this conference. This volume contains papers selected for presentation and includes the two keynote talks by Prof. Hector Garcia-Molina and Prof. Gerhard Weikum, and an invited talk by Dr. Xiao Ji. This volume also contains industrial papers and demo/poster papers. An additional volume contains papers from 6 workshops. The conference also featured three tutorials: (1) Web Change Management andDelta Mining: Opportunities andSolutions, by SanjayMadria, (2)A Survey of Data Quality Issues in Cooperative Information Systems, by Carlo Batini, and (3) Visual SQL - An ER-Based Introduction to Database Programming, by Bernhard Thalheim.

Coverage in this proceedings volume includes data mining and knowledge discovery, wireless, sensor networks and grid, XML and query processing and optimization, security, information extraction, semantic Web and Web applications, and workflow and middleware.
