Research Summary

Koiti  Hasida(D.Sci.)

The operation of the society heavily depends on the precision and efficiency of people's documentation (by text, video, etc.) of semantic content (knowledge, belief, intention, desire, etc.) and of their comprehension of documents. Besides, people and AI must share semantic content with higher precision and efficiency in order for AI to provide sufficient values to people. However, precise and efficient composition and comprehension of documents are hard for people. We are investigating formats and user interfaces for people to more precisely and efficiently read and write, and AI technologies to assist composition, comprehension and other advanced utilization of documents.
