This volume includes the papers accepted for the First International Conference on Electronic Commerce and Web Technologies, which was held in Greenwich, UK, on September 4-6, 2000. The conference is the first of a series of planned conferences on these topics with the goal to bring together researchers from academia, practitioners and commercial developers from industry, and users to assess current methodologies and explore new ideas in e-commerce and web technology. The conference attracted 120 papers from all over the world and each paper was reviewed by at least three program committee members for its merit. The program committee finally selected 42 papers for presentation and inclusion in these conference proceedings. The conference program consisted of 14 technical sessions and two invited talks spread over three days. The regular sessions covered topics such as web application design, intellectual property rights, security and fairness, distributed organizations, web usage analysis, modelling of web applications, electronic commerce success factors, electronic markets, XML, web mining, electronic negotiation, integrity and performance, facilitating electronic commerce, and mobile electronic commerce. There were two invited addresses at the conference. The first was by Anthony Finkelstein, University College London, UK on "A Foolish Consistency: Technical Challenges in Consistency Management". This was a common address to the DEXA, the DaWaK and the EC-Web attendees. The second talk was by Paul Timmers, European Commission, Information Technologies Directorate on "The Role of Technology for the e-Economy".

The Third International Conference on E-commerce and Web Technology (EC-Web 2002) was held in conjunction with the DEXA 02 in Aix-en-Provence, France. This conference, first held in Greenwich, United Kingdom in 2000, is now in its third year and is very well established. As in the two previous years, it served as a forum bringing together researchers from academia and commercial developers from industry to discuss the current state of the art in E-commerce and web technology. Inspirations and new ideas emerged from intensive discussions during formal sessions and social events. Keynote addresses, research presentations, and discussions during the conference helped to further develop the exchange of ideas among the researchers, developers, and practitioners who attended. The conference attracted more than 100 submissions and each paper was reviewed by at least three program committee members. The program committee selected 40 papers for presentation and publication, a task which was not easy due to the high quality of the submitted papers. We would like to express our thanks to our colleagues who helped to put together the technical program: the program committee members and external reviewers for their timely and rigorous reviews of the papers, and the organizing committee for their help in the administrative work and support. We owe special thanks to Gabriela Wagner and Maria Schweikert for always being available when their helping hand was needed.

We welcome you to the 6th International Conference on E-Commerce and Web Technology (EC-Web 2005) held in Copenhagen, Denmark. It was held in conjunction with DEXA 2005. This conference was organized for the first time in Greenwich, UK, in 2000, and it has been able to attract an increasing number of participants and interest, reflecting the progress made in the field. As in the five previous years, EC-Web 2005 served as a forum that brought together researchers from academia and practitioners from industry to discuss the current state of the art in e-commerce and Web technologies. We are sure that inspirations and new ideas emerged from the intensive discussions that took place during the formal sessions and social events. Keynote addresses, research presentations and discussions during the conference helped to further develop the exchange of ideas among current researchers, developers and practitioners. The conference attracted 139 paper submissions and each paper was reviewed by three Program Committee members. The Program Committee selected 39 papers for presentation and publication (an acceptance rate of 28%). And we have to confess that this task was not that easy due to the high quality of the submitted papers.
