Abstract
An information analysis device includes a correlation value calculation unit which specifies the number of appearances of links between one linguistic expression and other linguistic expression and an appearance time of each link based on link information. The correlation value calculation unit calculates a correlation value between the one linguistic expression and the other linguistic expression according to a degree that the link continuously appears by using the specified number of appearances of the link and the appearance time of each link.
