Hitachi Developed Basic Artificial Intelligence Technology that Enables Logical Dialogue

Tokyo, July 22, 2015 --- Hitachi, Ltd. (TSE: 6501, “Hitachi”) today announced that it has developed a technology that analyzes huge volumes of text data on issues that are subject to debate, and presents reasons and grounds for either affirmative or negative opinions on those issues in English. This technology focuses on values such as health, economics and public safety, which are considered important to people and communities when expressing opinions, and uses correlations between those various values and relevant issues in the society to identify reasons and grounds with a high degree of reliability from among large volumes of news articles. By using multiple viewpoints, it is able to present reasons and grounds without bias toward a single perspective.
