This book constitutes the proceedings of the 7th Workshop on E-Business, WEB 2008, held in Paris, France, on December 13, 2008. As a pre-ICIS workshop, it provided an open forum for e-business researchers and practitioners to share research findings, explore novel ideas, discuss success stories and lessons learned, and map out major challenges with regard to the design of e-business systems. The 17 papers presented were carefully reviewed and selected from a total of 31 full papers and 30 research-in-progress papers that were accepted for presentation at the workshop from a large number of submissions. The topics covered are electronic markets, electronic services, radio frequency identification, service-oriented architectures, virtual communities, and Web intelligence.
