Kawahara Lab at Department of Communications and Computer Engineering,
Waseda University

About

We study and develop artificial intelligence systems that can understand language like humans.
In particular, by combining findings and technologies of computer science and linguistics, we work on world knowledge acquisition/utilization and text analysis/understanding.
Furthermore, we aim at elucidating the mechanisms by which humans understand language and developing systems which incorporate such mechanisms.
