Engaging in initial communication interactions with an unknown partner for the first time can be a daunting task. Participants often use several different strategies, including an active strategy involving getting to know their communication partners through asking other people about them. However, this strategy might not always be possible. To resolve the situation when this strategy is not suitable, we propose a method to extract keywords from the partner's comments on SNS sites and use these comments to represent their interests and activities. Keywords are visualized as a mind map for use as a communication tool when engaging in interpersonal communications. The use of this method is demonstrated and evaluated in three examples that were created from real world data collected from Twitter.
