The proposed system is designed to support the dynamic formation of human relationships between strangers in networked virtual space. This system attempts to locate the most suitable virtual space for the content of their conversation. The system analyzes the conversation by using morphological analysis and provides candidate virtual spaces related to the conversation topic. Users can change the conversational space freely by choosing one of the candidates. The new virtual space, tailored to the participants' conversation, can potentially enhance the quality and satisfaction the participants perceive during their virtual relationship. In this paper, we describe the implementation and experimental evaluation of our proposed system. Our results show that by placing users in virtual settings that are "aware" of their conversation topics, we can created a compelling and powerful communication paradigm, potentially enhancing the quality of the resulting human relationship.
