Advances in Web, Internet and mobile technologies offer new and exciting services to users in various domains such as e-business, healthcare, entertainment, and scientific activities. However, the effective processing and management of the information services in a large scale distributed and complex environment create new challenges for the research community of the web and mobile services. This workshop aims to bring together researchers in an effort to highlight the state-of-the-art and discuss the issues and opportunities to explore new research directions and develop new ideas. We strongly welcome submissions that include results which advance the state of the art relating to the theme of the workshop, either  through theoretical analysis or experimental analysis. The main topics to be addressed include (but not limited to):

·   Architectures for Web and mobile information services

·   Data models and query languages for web and mobile systems

·   Searching and discovery techniques

·   Performance and reliability aspects

·   Context oriented service provisioning

·   Agent-based services

·   Fault tolerance and exception handling

·   Transaction and workflow models

·   Agent and multi-agent systems and their applications

·   Semantic web technologies and their applications

·   Monitoring of services

Publication

Only full papers will be accepted. The length of the paper is limited to 6 single-spaced double column IEEE format pages. Papers should be submitted by emails only to the workshop organizers. All papers will be reviewed by at least two independent reviewers.

Accepted papers will be published by IEEE CS Press as IEEE 21st AINA 2007 Workshops Proceedings. Authors of high quality papers presented in the workshop will be invited to submit extended version of their papers for publication in the Journal of Service Oriented Computing and Applications, Springer. In previous years, selected papers were published in two well known international journals — Journal of Information and Software Technology and Journal of Computer and System Sciences, Elsevier Science.
