Semantic Web Enabled Web Services
Dieter Fensel

Abstract
Currently, computers are changing from single, isolated
devices into entry points to a worldwide network of information exchange
and business transactions called the World Wide Web. However, the easy
information access based on the success of the web has made it
increasingly difficult to find, present, and maintain the information
required by a wide variety of users. In response to this problem, many new
research initiatives and commercial enterprises have been set up to enrich
available information with machine-understandable semantics. This semantic
web will provide intelligent access to heterogeneous, distributed
information, enabling software products to mediate between user needs and
the information sources available. Web Services tackle with an orthogonal
limitation of the current web. It is mainly a collection of information
but does not yet provide support in processing this information, i.e., in
using the computer as a computational device. Recent efforts around UDDI,
WSDL, and SOAP try to lift the web to a new level of service. Software
programs can be accessed and executed via the web. However, all these
service descriptions are based on semi-formal natural language
descriptions. Therefore, the human programmer need be kept in the loop and
scalability as well as economy of web services are limited. Bringing them
to their full potential requires their combination with semantic web
technology. It will provide mechanization in service identification,
configuration, comparison, and combination. Semantic Web enabled Web
Services have the potential to change our life in a much higher degree as
the current web already did.

Bio
Dieter Fensel is an associated professor at the Vrije Universiteit
Amsterdam in the area of business informatics. After studying mathematics,
sociology and computer science in Berlin, he joined in 1989 the Institute
AIFB at the University of Karlsruhe. His major subject was knowledge
engineering and his PhD thesis in 1993 was about a formal specification
language for knowledge-based systems. From 1994 until 1996 he visited the
SWI Department in Amsterdam. During this time his main interest were
problem-solving methods of knowledge-based systems. In 1996, he come back
as a senior researcher at the Institute AIFB finalizing his Habilitation
in 1998. Currently, his foccus is on the use of Ontologies to realize
semantic web technology and to apply it in knowledge management and
electronic commerce.

He has published around 150 papers as books and journal, book,
conference, and workshop contributions. He organized around 100 scientific
workshops and conferences and has edited several special issues of
scientific journals. He is associated editor of Knowledge and Information
Systems: An International Journal (KAIS), Springer-Verlag, and IEEE
Intelligent Systems. He is involved in several national and internal
research projects, for example, in the running IST projects Htechsight,
IBROW, Multiple, Obelix, On-to-Knowledge, Ontoweb, SWAP, and Wonderweb.
Dieter Fensel is the author of the books Ontologies: Silver Bullet for
Knowledge Management and Electronic Commerce, Springer-Verlag, Berlin,
