Elsevier published our work on Semantic Web Services with Lightweight Descriptions of Services in its Advances in Computers, volume 76 (co-authored by me, Jacek Kopecky, Jana Viskova, Adrian Mocan, Mick Kerrigan and Dieter Fensel). In order to publish in this book, authors need to receive an invitation from Elsevier and we were glad to receive such invitation in 2008. This book’s topic is about foundations and applications of Semantic Web including Social Web and Web Services.
