In this study,we investigate the correlation between stock price and Web data.In previous research, it had been reported that there are some relation between the tweets of Twitter.Analysis of the Web data has shown that it is useful for the prediction of stock price from the result. We examine whether approach of previous research is useful for Web data in Japan.We also researched the correlation between stock price and Web data.We applay the negative-positive analysis to news articles of domestic news site. We quantified the article of domestic news sites to negative or positive of the two types of value emotional value,and analyzed the relationship between stock price.From the experimental results, we found that there is a certain tendency but it is difficult to show the correlation using only negativepositive analysis.
