Abstract
Information has many ways to use, and the kind of information and quality of information changes with usages. For example, the bestseller information is important, and the long-term seller information is important as well. Why? The reason for this is that the long-term seller information is used many users for a long time. As opposed to this, there are many access technique of the bestseller information, but there are few access technique of the long-term seller information. As a result, it is difficult for us to access the information that is used for a long time but it isn't the bestseller.
Therefore, we proposed a general idea that is long-term degree, and we developed the system that selects and gets the long-term seller information.
