The theme of the XML Database Symposium (XSym) is the convergence of database technology with XML technology. Since the first International XML Symposium in 2003, XSym has continued to provide a forum for academics, practitioners, users and vendors to discuss the use of and synergy between advanced XML technologies. XSym 2006 received 32 full paper submissions. Each submitted paper underwent a rigorous review by independent referees. These proceedings represent a collection of eight excellent research papers. Their focus is on building XML repositories and covers the following topics: XML...

Fifteen years after the publication of Weiser s seminal paper in Scientific American, ubiquitous computing is a large, thriving field of academic research and commercial innovation. The proceedings of the 8th International Conference on Ubiquitous C- puting reflect the strength, diversity and vigor of the research program that Weiser initiated. We hope that you will find much in the papers contained herein to stimulate new and exciting work as we reach forward toward ubiquitous computing together. The location of the conference, in Orange County, California, was particularly - posite given...

This time we received 120 submissions from 27...

Since its establishment in 1995, the ERCIM Working Group User Interfaces for 1 All (WG UI4ALL) has systematically promoted the proactive realization of the design for all principles in HCI. Its activities have included the organization of a se- 2 ries of very successful workshops that have contributed to consolidate recent work and stimulate further discussion on the state of the art in user interfaces for all and its increasing range of applications in the upcoming Information Society. Such wo- shops have brought together, in a new scientific community, researchers and teams working not only...

EGOV 2007 was the sixth edition of this highly successful series of annual int- national conferences dedicated to electronic government research and practice. Like all its predecessors, EGOV 2007 achieved a remarkable number of paper submissions. Moreover, the quality of this year s submissions again superseded previous years submissions. For the third year in a row, the conference was anteceded by a doctoral colloquium, with approximately 20 PhD projects d- cussed. The conference also provided a forum for academic work in progress, for practitioner reports, and for workshops on specialty...

Data Warehousing and Knowledge Discovery have been widely accepted as key te- nologies for enterprises and organizations to improve their abilities in data analysis, decision support, and the automatic extraction of knowledge from data. With the exponentially growing amount of information to be included in the decision-making process, the data to be processed become more and more complex in both structure and semantics. Consequently, the process of retrieval and knowledge discovery from this huge amount of heterogeneous complex data constitutes the reality check for research in the area....
