Knowledge is increasingly gaining attention as a competitive advantage and core competency. The future challenge, therefore, lies in preserving knowledge and specialist know how with a systematic knowledge management approach, enable quick access to required knowledge and to create and transfer new knowledge more easily and more quickly. Conventional knowledge management relies on theprocessing of quantitative data. Qualitative data, like texts, multimedia files, however, are also very important sources of knowledge. In order to use them effectively in research and development, economy, culture and technology these so-called "soft" data must be analysed and processed systematically. The research project was funded by the German Federal Ministry of Education and Research (BMBF) and has developed primarily web based knowledge services.
