Process models of semantic web

The aim of this work is to explore the possibility of using the process models in the world of semantic web and the increase utilization of information from the semantic web. This software aims to add a lot of useful functionality to Trisolda, the infrastructure of the semantic web. It was analyzed that proposing of distributed system based on semantic services technology is an appropriate solution. The collaboration of several services is best described by the word "orchestration" that mean operating of executers by the conductor. BPEL (Business Process Execution Language) language is used for formalization of various processes. The proposed architecture is enlarged by pilot implementation that goal is to examine possible technologies that can be used to the realization. Several BPEL execution engines were tried before ActiveVOS platform was chosen as the most suitable one. The use of this platform is described in this work. The description of applied technologies and the confrontation with other existing projects is also a part of this thesis
