Despite statistics released by the government or central banks have been used to grasp the economic trends, there is a lag in the timing of the survey and publication of the results. Therefore, there have been a lot of research to estimate them ahead of the publication. In this research, we tried to quantify the economic sentiment indicator by analyzing the huge amount of text data created and accumulated in financial institutions. As a result, it was found that our indicator had a high correlation with the Bank of Japan TANKAN, short-term economic survey of enterprises in Japan, and also had a quick reporting nature.
