In this paper, we present a method and its implementation to aid the process of building knowledge out of chunks of information. The chunks of information, which can be the source of new knowledge, often exist in so called tacit dimension. This paper deals with these unclassified chunks of information that haven't been systematized yet but has potential to be systematized. In order to aid the process of building knowledge out of those chunks, we give a system which maps the chunks into a metric space. Through the reconfiguration of this space, the user can gradually structurize the chunks of information into systematized knowledge. The unique feature of the proposed system compared with the existing ones lies in the function to deal with the users point of view. The system reveals the user's hidden point of view explicitly, and this helps the process of systematization of knowledge much. We have implemented a system CASSIS, which stands for Computer-ASSIsted Systematization, and have carried out several experiments. We show the configuration of the system and the results of the experiments.
