Abstract
The invention provides a user age estimation method based on mass data and a user age estimation system based on mass data. The method comprises the following steps: obtaining basic age data of a user, assigning an initial weight value to the basic age data; obtaining an age weight value of the user in different basic age data according to the initial weight value and age similarity of the user in different basic age data; and finding out the age with the maximum age weight value in the basic age data, and taking the age with the maximum weight value as an initial estimation age of the user. The user age estimation method and system based on mass data can enhance accuracy of user age estimation.
