Summary: 
Blog enables users to easily and rapidly publish personal activities and interests. They are considered as important information from viewpoints of sociology, and marketing. This paper presents a novel system for analyzing temporal changes in activities and interests of bloggers through a 3D visualization of phrase dependency structures of their mentions. We implement the proposed system on our own five years blog archive focused on Japanese, and show the usefulness of our system by some examples.
