It is our honour and pleasure to invite you to join the Third International Conference on Information Integration and Web-based Applications & Services. This year's iiWAS will be held in Linz Austria, September 10-12. We are looking forward to your contribution and participation in iiWAS2001. We rejoice to welcome you in Linz.

iiWAS is now the international conference on Information Integration and Web-based Applications & Services. It follows IIWAS1999 and IIWAS2000 international workshops on Information Integration and Web-based Applications & Services held in Gadja Madah University, Yogyakarta, Indonesia. These two workshops have been successful international events gathering papers from countries as diverse as Australia, Malaysia, USA, Spain, Holland, Norway, or Taiwan with outstanding speakers such as Philippe Bonnet from Cornell University, Leon Sterling from the University of Melbourne, A Min Tjoa from the Vienna University of Technology, and R. Sadananda from Asian Institute of Technology among many others.

As Internet based applications and services continue to evolve very rapidly, new and exciting opportunities for information integration systems are constantly created. We are witnessing a tremendous growth in the number, types, and novelty of information integration systems, as well as an increased level of sophistication. iiWAS2001 is a forum of discussion and presentation of new ideas and technologies for value adding services in information integration and web-based applications and services. The goal of the conference is to bring together practitioners, researchers, users and information providers involved in the development and deployment of commercial, industrial and practical applications to exchange ideas, present their recent research and discuss possible collaborations.
