Jos de Bruijn received his Master of Science degree in Technical Informatics from the Delft, University of Technology, The Netherlands, in 2003. Since 2003 he is employed as a researcher at the Digital Enterprise Research Institute (DERI), at the University of Innsbruck, Austria. His research interests include Semantic Web (Services) languages, Logical languages, Logic Programming and Non-Monotonic Reasoning. He is the main architect of the WSML language. Dieter Fensel is the Scientific Director of the Digital Enterprise Research Institute (DERI) at the National University of Ireland, Galway in 2003, and the Director of the Digital Enterprise Research Institute (DERI) at the Leopold Franzens University of Innsbruck, Austria in 2006. His current research interests are around the usage of semantics in 21st century computer science.

From the reviews: "This book ... is essential for every scholar or professional who is serious about semantic Web services" from the ACM Reviews by Mariana Damova, Mozaika, Sofia, Bulgaria "This book introduces the new Web service modeling language (WSML), a semantic Web-based formal language for automating Web services-related tasks. The target audience of the book is listed as professionals, academics, and industry researchers. ... it is more suited for researchers who are interested in obtaining in-depth knowledge of WSML. ... In conclusion, this is a well-organized and well-written book. I highly recommend it to researchers interested in learning about WSML." (Rajani S. Sadasivam, ACM Computing Reviews, May, 2009)
