The purpose of this study is the establishment of a method and the development of a supporting system for educating personnel involved in care management by computer. We propose a system in which know-how information can be shared. We consider that visualizing and showing care plans drawn up by experts in various forms allows a beginner to see the differences between a novice plan and an expert plan. Sharing know-how information is possible by recording, accumulating, and giving titles to what has been noticed by comparing documents. This system can visualize the similarities among documents that interpreted the results of an assessment and can flexibly change viewpoints. Additionally, it can map several users' new documents into a two-dimensional document space. In this paper, we report an improvement of a model case, new function and the design of the experiment.
