This book constitutes the joint refereed proceedings of the two workshops held in conjunction with the 5th International Conference on Web Information Systems Engineering, WISE 2004 in Brisbane, Australia in November 2004.
The 21 revised full papers and 5 revised short papers presented were carefully reviewed and selected for inclusion in the book. The papers are organized in topical sections on ontologies for networked systems, mobile learning, fragmentation versus integration perspectives of the web information systems discipline, and web services quality.
