Knowledge maps as lexical signatures of journals papers and patent documents

The transfer of knowledge from research laboratories and academic seminars to the industrial/commercial sector is a strategically important issue. Text analysis of journal papers and patent documents, written by one scientist and his team in the specialist area of semiconductor physics, has been performed in order to visualize the cross-over of research knowledge onto patented artifacts. The results shows the time lag in the cross-over and will serve to bring knowledge visualization and information extraction techniques in the rather quantitative arena of strategic policy making in science and its application to technology.
