This tutorial will give a comprehensive overview of the current status of research
and development with in the arena of Semantic Web Services (SWS). Semantic Web
Services is the application of semantic web technology to overcome the current
deficiencies of the Web service technology stack. The incorporation of ontology
based description frameworks extends the current syntactic technologies (SOAP,
WSDL, and UDDI) facilitating the automation of all tasks associated with the
creation of applications from web services, namely, web service invocation,
discovery and composition.
More specifically the concrete aims of the tutorial are (1) to make attendees
familiar with the concepts, ideas, and techniques of Semantic Web services,
(2) to provide a comprehensive overview on the state of the art in SWS frameworks,
techniques, and standardization efforts, and (3) to enable and assist attendees
with practically modeling and utilizing Semantic Web services within an exhaustive
hands-on session. As a full-day event, this tutorial will provide newcomers
as well as experts in the field with a wide-ranging and up-to-date overview
on Semantic Web Services. The concepts within this tutorial are based on ongoing
work within a number of large European projects, including DIP, SEKT, ASG and
KnowledgeWeb, and as such have been tried out and honed in a number of preceding
events and within a number of industrial case studies within the Banking, Telecoms
and Government domains.
The following provides the material for the tutorial for download. This consists of the slide set, and a software package that will be used during the practical hands-on session. We encourage attendees to download the material, for taken notes during the tutorial and to actively participate in the practical part.
The tutorial consists of three main sections that subsequently provide a complete overview of Semantic Web Services and the latest status related technology developments. The tutorial is centered around the Web Service Modeling Ontology WSMO an established framework which all the presenters have contributed to, and then discuss differences and commonalities with other efforts. The tutorial parts will be presented in order explained below.
This section introduces the idea and challenges of Semantic Web Services, as the basis of the subsequent sections comprising the following aspects:
In order to provide sophisticated solutions for Semantic Web Services, technologies need to be positioned in an overall framework. The Web Service Modeling Ontology WSMO (see homepage: http://www.wsmo.org) is a broad framework that defines the core elements for semantically enabled service-oriented computing, providing the basis for realizing the next generation of IT technology. This section introduces WSMO with regard to:
The Web Service Execution Environment WSMX (see homepage: http://www.wsmx.org/) is a software environment for semantically enabled, goal-driven Web service usage. It is the reference implementation of WSMO reference implementation. This section presents WSMX by:
In order to actively participate in the hands-on session, we request attendees to download and install the software package provided above (see Material)
In the afternoon, attendees practically create and work with Semantic Web Services on basis of the techniques and systems presented in the previous tutorial parts. As another implementation of the WSMO framework, the Internet Reasoning Service IRS III is a semantically enabled broker for Web service usage. Experience in previous tutorials has proven this section as very helpful for attendees, as the most you learn we you actually do it yourself. The hands-on session is run in small working groups of attendees that are lead by one presenter and is structured as follows:
In order to actively participate in the hands-on session, we request attendees to download and install the software package provided above (see Material)
Semantics and Web services are considered as the basis for the next generation of IT systems. As the first set of research results have been released, attention arises within industry for settling in future markets. Concurrently, in order to provide a sound technical basis for future product development and market adoption, standardization efforts commence for Semantic Web and for Semantic Web services. For conclusing the tutorial, we give an overview on this, including:
The tutorial will be presented as a full day event. The following table provides the planned time schedule.
| Time | Content |
| 09.00 | Start, welcome |
| 09.00 – 09.15 | Section 1: Introduction to Semantic Web Services |
| 09.15– 10.30 | Section 2: The Web Service Modeling Ontology WSMO |
| 10.00 – 10.30 | Coffee break |
| 10.30 – 11.30 | Section 3: WSMX System Presentation |
| 11.30 – 12.30 | Section 3: WSMX Hands-On Session |

| 16.00 – 17.00 | Section 4: Hands-On Session |
| 17.00 – 17.15 | Section 5: Wrap-up, Closing |
The tutorial addresses academic as well as industrial researches and developers that are working with Web technologies in general and have specific interests in Web services and the Semantic Web.
Attendees will gain a detailed understanding of the aims and challenges of Semantic Web services, understand the design and specification of overall frameworks, get to know existing tools and implementations for Semantic Web Services, and be able to apply and assess most recent Semantic Web Service technologies to their specific work or project.
Although no specific knowledge is demanded as a pre-requisite for attending the tutorial, basic knowledge about ontologies and Web Services will allow attendees to better understand and follow the tutorial.
The tutorial is presented by experts in Semantic Web services that have been engaged in Semantic Web services from early on in European and intercontinental research (see presenter information below). It builds upon experience several preceding tutorials that have been presented at respective international events in the past 2 years, e.g.: 2004 international conferences: AIMSA, Net Object Days, ISWC; 2005 international conferences: ESWC, ICAC, ICWS, ICWE, ISWC; 2006 conferences: HICSS, ICIS, ESWC, CSWWS, AAAI; detailed information on all previous tutorials can be found at: http://www.wsmo.org/TR/d17/.
