Accumulation of information is essential for human knowledge production, and information technology has accelerated the speed of data accumulation. The increase in quantity of information with high speed does not promise highquality knowledge production and possibly does cause problems. One big problem is lack of storage for such big data. Another critical problem in information usage is information overload, that is, deterioration of productivity by too much information. Decision accuracy decrease with amount of information beyond a certain point while it increases at the beginning. We introduce an approach for solution of these problems with an example of research along the approach.
