Hitachi Develops Basic Artificial Intelligence Technology that Enables Logical Dialogue in Japanese

Tokyo, June 2, 2016 --- Hitachi, Ltd. (TSE: 6501; “Hitachi”) today announced that it has developed a basic artificial intelligence (AI) technology that analyzes huge volumes of Japanese text data on issues that are subject to debate, and presents in Japanese both affirmative and negative opinions on those issues together with reasons and grounds. In this research, Hitachi applied deep learning*1 to the process of distinguishing sentences representing reasons and grounds for opinions, eliminating the need for a dedicated program to be prepared for each language and thus enabling the creation of a general-purpose system analyzing text data in any language. Previously, Hitachi developed a basic AI technology which analyzed huge volumes of English text data and presented opinions in English.*2 This time, Hitachi incorporated this technology into a new AI technology for the Japanese language to meet the needs of Japanese enterprises.
