Welcome from the chairs

Welcome to the 12^th annual meeting of the IEEE International Symposium on Web Systems Evolution (WSE 2010). Since its inception in 1999, the Symposium has attracted leading technical people both from industry and academia, with the purpose of discussing and debating new and emerging technologies in the area of Web systems. The Symposium was originally conceived with the title International Workshop on Web Site Evolution as a forum for the analysis, maintenance and evolution of Web sites, with emphasis on sites with dynamic and diverse content. However, the technological trends of the recent years, and the emergence of Service Orientation as a predominant paradigm for offering, brokering, and using software applications over the Web led to the expansion of the Symposium and to the consequent change of its name to its current title. The quality of the papers that the Symposium has attracted over the years, and its impact to the community, is due in part to sponsorship from the Institute of Electrical and Electronics Engineers (IEEE) - support that the Symposium recognizes.
