The conference will bring together the world's most respected authorities on semantic web, Web based services, Web applications, Web enhanced business information systems, e-education specialists, Information security, and other Web related technologies. The aim of NWeSP'13 is to serve as a forum to present current and future work as well as to exchange research ideas in this field. NWeSP'13 invites authors to submit their original and unpublished work that demonstrate current research in all areas of Web based information systems and their applications in science, technology, business and commerce. The conference is expected to provide an opportunity for the researchers to meet and discuss the latest solutions, scientific results and methods in solving intriguing problems in the fields of Web Services. The conference programme will include workshops, special sessions and tutorials, along with prominent keynote speakers and regular paper presentations in parallel tracks.
