Knowledge Web project, a four-year EU R&D project, comes to its end by the end of this year. The project forms the Semantic Web community in Europe while contributing to the cutting edge research and development of semantic technologies along the lines of education, research and industry. My major contributions were in the research area with focus on the semantic web and its adoption by web services enabling automation of services tasks. Over the past three years, I worked as the leader of these activities and, thanks to the project, we were able to make a significant contribution in the semantic web services community. Here are our major achievements:

• Development of the WSMO, a service ontology.
• Development of the WSML, a language for Semantic Web Services,
• Development of the WSMX, a middleware system and architecture for Semantic Web Services execution;

Along the above lines, we contributed to the development of the SWS Challenge, a methodology and testbed for the Semantic Web Services as well as solutions for the challenge scenarios, standardizations in OASIS (SEE TC, Semantic Execution Environment Technical Committee), and standardizations in W3C (SAWSDL, Semantic Annotations for WSDL and XML Schema) and published over 60 papers in conferences and journals.

With the end of the project, these activities will not come to the end. We will further continue developing the lightweight ontology for Semantic Web Services (known as WSMO-Lite), services mashups powered by the semantic technologies and related services tasks. There is a number of follow up projects such as SOA4ALL, Service Web 3.0, etc. where all these activities will find its place.
