(1) Data mining from large and complex networks
We study the basic technologies for understanding a huge, irregular and ever-growing complex networks, such as the Web, and then making effective use of it for knowledge navigation. Our approach includes:
(2) Understanding the real world situation by sensor networks
We are interested in observing and interpreting the real world by a variety of sensing devices such as acceleration sensor, light sensor, GPS, camera, and microphone. Some research examples are
(3) Dialogue system that appeals to user's thinking and emotion
We conduct research on the development of such a dialogue systems that appeals to user's thinking and emotion appropriately. Unlike traditional dialogue system that is focused on the accomplishment of a certain task (such as seat reservation), our intended system aims at increasing the user's satisfaction by joyful and interesting conversations. We study how to estimate the user's thinking and emotional state through a dialogue, and also how to lead the user's state to a better one.
Feature of the Laboratory
Our research activity goes through verious phases, such as proposing a new theory and model, developing an effective algorithm and data structure, and applying techniques to a new interesting application. We are interested in processing verious kinds of data, for example the Web data, language data, speech sounds, images, sensor data. Our everyday's efforts are for aiming at the world's first proposal and verification of a new technique, or the world's best performance for a certain task. Each researcher has his/her own booth in a broader room where some conversations occasionally happen. A more heated in-depth discussion with several researchers is conducted in a discussion room, where a whiteboard is equipped.
