Editorial: Moving to the Fifth Year of TSC

2 marks the fi fth year of the IEEE Transactions on Services Computing (TSC). Since the fi rst issue launched in 2008, TSC has published 16 issues. TSC has played an important role in contributing to the creation of the Services Computing discipline. In the past four years, TSC has created the Taxonomy for Services Computing to help lay a foundation of the framework of body of knowledge on services computing. There are 14 key knowledge areas spanning from services systems, services lifecycle, web services, service oriented architecture, services relationships, services composition, and business process management and integration, to enterprise modeling and management, service-oriented consulting methodology, cloud computing, services delivery platforms and methodology, application services and standards, security and privacy in services, and IT services management. The four published volumes of TSC have covered most of the top-level key areas of the body of knowledge in the fi eld of services computing. The TSC community has grown steadily. The authors are from more than 48 countries and regions. There have been more than 539 papers submitted. There are 33+ volunteers serving as editorial board members and more than 1,000 reviewers who have not only ensured the quality of the published papers in TSC, but also helped shape the ideas and research accomplishments of submitted papers. The readership has also grown from technical communities to services business and management communities. TSC has organized special sections or issues based on the highquality presentations from the set of prestigious conferences such as the International Conference on Web Services (ICWS), the International Conference on Services Computing (SCC), the International Conference on Cloud Computing (CLOUD), and the World Congress on Services (SERVICES). TSC has gradually gained broad acceptance in the community. TSC has been indexed by Thomson Reuters (ISI), EI Compendex, Science Citation Index Expanded (SCI-e), and other indexing systems. As the founding editor in chief of TSC, I am very pleased with the milestone TSC has achieved. I would like to take this opportunity to appreciate the continuous contributions from the authors, readers, associate editors, and reviewers, as well as the IEEE Computer Society staff and TSC assistants. Finally, I hope you enjoy reading the fi rst issue of TSC in 2012. I look forward to your continuous contributions as an author, reader, or volunteer.
