Research Area

1. Data mining from large and complex networks

We study the basic technologies for understanding huge, irregular and ever-growing complex networks, such as the Web, and then make effective use of them for knowledge navigation.

2. Understanding real world situations through sensor networks

We are interested in observing and interpreting the real world through a variety of sensing devices such as acceleration sensors, light sensors, GPS, cameras, and microphones.

Key Features

Our research activities include various phases, such as proposing new theories and modeling, developing effective algorithms and data structuring, and applying techniques to new interesting applications. We are interested in processing various data, for example Web and language data, speech sounds, images, and sensor data. Our everyday efforts are aimed at the world's first proposal and verification of new techniques, or the world's best performance of certain tasks. Each researcher has a booth in a broader room where discussions occur naturally. More heated, in-depth discussions with several researchers are conducted in the discussion room.
