RIKEN Center for Advanced Intelligence Project Language Information Access Technology Team
Team Leader: Satoshi Sekine (Ph.D.)
Research Summary
Most of the information in the world is provided in natural language. Due to the huge amount of information, we face serious difficulties to access necessary information. In order to solve the information access bottleneck problem, we will work on the task of Information Extraction, Dialogue Systems and other areas of NLP. In particular, we believe it is crucial and essential that the automatic system can explain the decision it made in the application. We will open the horizon of the basic technologies and will build the useful application systems based on the NLP technologies.
