Akira Shimazu Professor
School of Information Science（Department of Information Science・Artificial Intelligence）
■Degrees
B.S., M.S. and Ph.D. from Kyusyu University (1971,1973,1991)
■Professional Career
Researcher at Musashino Electrical Communication Laboratories of Nippon Telegram and Telephone Public Corporation , and at Basic Research Laboratories of Nippon Telegraph and Telephone Corporation (1973-1997)
■Specialties
Legal Engineering, Natural Language Processing, Dialog Processing, Machine Translation
■Research Interests
Analysis of human language use:
An utterance in spoken language is not necessarily represented by a sentence as in written language, and information is conveyed from speaker to hearer in rather small phrasal units with disfluencies such as fillers and self-repairs. Such characteristics are pertinent to human information processing and communication, and analyzed for an advanced natural language processing system.
Dynamic explanation of information
Research which clarifies principles and techniques for explaining information as a human explains information to a recipient in spoken language. The research is based on the analysis of human language use. Not only spoken language systems but also application to web access are within the scope.
Natural language processing based on statistical models
Researches on semantic analysis, machine translation, ambiguity resolution based on corpus and machine learning.
Study on Legal Engineering - Legal Document Processing -
Our society is regulated by a lot of laws and rules which are related mutually. When we view a society as a system, laws and rules can be viewed as the specifications for the society. Such a systemic aspect of laws and rules have not been studied well so far. In the upcoming e-Society, laws and rules have more important roles in order to achieve a trustworthy society and we expect a methodology which treats a systemic aspect of laws and rules. Legal Engineering is a new eld which studies the methodology and applies information science and software engineering to laws and rules in order to support legislation and to implement laws and rules using computers. Since laws and rules are represented in natural languages, as a fundamental study on Legal Engineering, we study methods for processing legal documents such as analysis of law structures, support of legislation, search for legal information and law description language with high readability.
