Abstract: Knowledge Visualization is rather a new area of research and development. Its appearance is caused by the fact that the range of well investigated and established concepts of Data visualization and Information visualization implemented and integrated in different standard tools and applications cannot provide an adequate support for various activities and/or decision making. But exact this is the requirement on modern computing tools and approaches they have to satisfy in the long list of applications in business, administrations etc. The popular visualization of Data and Information in tables, diagrams, and other medial graphical techniques is focused and presupposes the professional knowledge by user in the application area e.g. to be able to make a decision. To improve these visualization approaches and platforms in order to enable the knowledge visualization one has to analyze origin of it and its role in different processes.
Outgoing point of such analysis is the subdivision of knowledge into declarative and procedural ones. The first is focused on description of objects, events etc. and its visualization is similar to those of Data and Information. The procedural knowledge is focused on activities, handling etc. and its visualization is consequently differs from those of Data or Information visualization. Presented paper describes the decisive aspects of professional knowledge in the context of its visualization and the utilization of this knowledge in selected application areas.

Brief Biography of the Speaker:
Wladimir Bodrow graduated from the Rostov-on-Don State University, Russia in 1975 where he studied theoretical Physics and Informatics. In the 1970s he worked as a senior researcher at the Rostov-on-Don University in the area of theoretical plasma physics. From 1979 till 1984 we worked at the physics department of Ernst-Moritz-Arndt University in Greifswald, Germany. Here he made his PhD project in the field of computing experiments in Plasma. Five years from 1984 until 1989 he worked as a team leader in research center of power provider. He developed the standard solutions for intelligent applications for energy industry. In 1990 Dr. Bodrow changed to University of Applied Sciences Berlin where he works a professor in the department of Business Informatics. His main area of teaching and research is Intelligent Applications in Business, Knowledge Management, Knowledge Based Systems, and e-Learning. As a leader of the knowledge visualization competence center at the university he investigates corresponding concepts and develops solutions to improve or enable different knowledge intensive business applications. He is author of several Books and about 80 papers published in international journals and conference proceedings, and invited book chapters.
