This book constitutes the thoroughly refereed post-conference proceedings of the 4th International Conference on Web Information Systems and Technologies, held in Funchal, Madeira, Portugal, in May 2008. The 32 papers presented in this book were carefully reviewed and selected from 238 submissions, resulting in an acceptance rate of 13.5%. The papers are grouped in four parts on internet technology, Web interfaces and applications, society, e-Business, and e-Government, and e-Learning. In addition, four invited papers complete this volume.
