Tsuneo Kuwabara

Position Professor
Research
Description
I am currently researching information system from the point of view of "computers helping humans."
For example, we have developed an e-learning system which enables even one instructor to support dozens of students individually in real time. I am also investigating new business models using IT and developing a means and tool to evaluate the usability of IT systems. Furthermore, I am investigating more manageable software development methods. I am also applying the cognitive psychology to my research and investigations.

Tomonori Gotoh

Position Professor
Research
Description
The number of internet users has recently exploded. Due to the sudden increase in web based information, I am researching search engines that require even greater accuracy. Specifically, I am investigating a method of accurately identifying and dividing compound words from multiple character types, such as long Chinese character combinations, the Katakana script, English letters and numerical characters which all exist in Japanese.
I am also researching how to improve the efficiency of search engines relative to large scale, high performance hardware. In addition, I am working tirelessly on investigating a method to visualize a knowledge structure for using information efficiently.

Shanjun Zhang

Position Professor
Research
Description
When people look at something, various information is taken in. I am currently researching the information processing function for visual recognition and applying this technology to computers.
The method I employ involves taking various image information with imaging devices such as CT scanners and cameras, etc., and depending on the objective or use, I distinguish “what type of patterns there are from the images.” Then, I extract that information, organize and analyze it. Image processing and pattern recognition is a technology that has and will play an invaluable role in an information based society becoming more sophisticated.

Takashi Nakayama

Position Professor
Research
Description
We are studying on natural language understanding and developing a dialogue system that converses with a human in Japanese. Specifically, we have been implementing common sense and domain knowledge in the form of a frame network. Question-answering system is one of the typical applications of natural language understanding. For instance, the user could quickly access things on the web, and complicated questions or inquiries could be responded correctly. The key is enabling the dialogue system to learn on its own. We are trying to achieve a flexible dialogue system that can acquire knowledge through web information and conversations.

Leo Nagamatsu

Position Professor
Research
Description
Nowadays, among the information systems that are heavily involved with many of our activities in society, the user's information system must operate without a break. The newest services ideally can be used right away. From the maintenance and management side, they must respond to problem areas quickly and any new functions also require functional architecture so that the user can access them without feeling any inconveniences.
My research aims to establish a configuration method to improve user-friendly information systems for both sides.

Kazuto Matsuo

Position Professor
Research
Description
Information security techniques have become indispensable for privacy protection, secure communications, and user authentication in today's Internet and mobile phone services. This laboratory carries out research on such information security-related themes as methods for implementing encryption algorithms and verifying security. With the main theme of these studies being algebraic curve cryptosystems, notably the elliptic curve encryption seen as the next-generation standard cryptographic technology, a wide range of research themes are taken up including ways of verifying the security of communication technologies in practical use such as Bluetooth.

Yoshiki Kinoshita

Position Professor
Research
Description

What is Science of Programming?

We do research in the Science of Programming in information processing systems in its broadest sense; they consist of computer hardware, software and even human operators who manipulate the machine. The target of our research includes computer programs, standardisation documents, laws and assurance cases which with the safety and security of computer programs and large-scale systems. A slightest error in these kinds of documents can lead to serious consequences such as airplane accidents, nuclear plant accidents and other disasters typical in modern society. Moreover, those documents change from time to time, so one must keep updating it without loosing the total integrity, which is a hard task to achieve. We study how to develop and maintain such huge collections of documents using mathematical tools such as mathematical logic and algebra. Science of Programming includes classical study areas such as “Semantics of Programs” (mathematical model of programs) and “Verification and Validation” (V&V, checking program correctness and confirming program validity).

Haruhiko-Kaiya

Position Professor
Research
Description
An information system demonstrates its worth only when it comes to be used in activities of work or daily life. Even if a system is developed properly with advanced functions and high quality, if it does not match the activities for which it is to be used, that system will be wasteful and only get in the way. The main research themes in this laboratory are requirement analysis, for analyzing what kind of information system is desirable for particular work or life activities, and specification notation, putting the requirement analysis results in a form that can be understood readily by developers. In requirement analysis, a model of real activities is described and a careful examination of the system usefulness is made on this model.

Ken Tanaka

Position Professor
Research
Description
My research focuses on investigating the optimization of network security, and in particular, optimizing packet filtering as the main technology for maintaining security. Packet filtering is the technology that expels or deletes malware, or potentially harmful things, from the maximum size packets which are delivered from the internet. As the types of potentially harmful packets increase, the rules also become more complex. As a result, I am investigating the possibilities of improving filter efficiency by reconstructing the rules.

Shogo Matsui

Position Associate Professor
Research
Description
My field of research is dedicated to programming language.
I mostly research functional and object-oriented language processing systems. I am aiming to establish a basic technology, such as parallel technology and memory management technology, that makes interpreter and compiler (software that executes written commands in both programming languages) operation faster and more efficient. Other research projects include and focus on garbage collection (memory garbage collection).

Antoine BOSSARD, Ph.D.

Position Assistant Professor
Research
Description
A graph is made of nodes and links. Graphs can be used to model many different situations. For instance, modern supercomputers are made of hundreds of thousands computing nodes; they are massively parallel systems. These nodes are connected according to the interconnection network of the system: nodes are processors and edges are links between them. Routing problems in this context are critical issues: they condition data communication efficiency and reliability. What would be the point of having numerous processors if they are not able to communicate with each other efficiently?
