In this paper, we present a visualization method of relationships among topics in a series of meetings. This method is an extension of the previous work: "A Topic Structuration Method for a Meeting from Text Data." The previous work is aimed at analysis of a single meeting, on the other hand, the proposed method is aimed at analysis of multiple meetings. Several meetings that belong to a single project might have common topics. Our visualization method helps us to find these common topics. In addition, the meetings might have isolated topics. Our method also helps to find them. This visualization is useful for review of meetings. We present a preliminary experiment. In the experiment, we show an analysis results of four actual meetings that belong to a single project.
