Popularization of smartphone allows many people to be able to share information, and easily get information they want. And then, app store of smartphone plays an important role to make users get information and make transactions they want easily. With the increase of the number of apps traded at the app store, it is difficult for users to find appropriate apps they want.

The experiment to test satisfaction of users showed that the method proposed in this paper increased the degree of satisfaction of users by over 21%.
