Fine marketing of color ring (i): How to determine the characteristics of the user's song age

The fine marketing of the color ring includes the similarity calculation and the http://www.aliyun.com/zixun/aggregation/37088.html of the song "> The mining of the user characteristics, relatively simple in the user's characteristic is the song chronology characteristic, the so-called song chronology characteristic, is a parameter that indicates which age the user likes, and today we'll talk about how to determine the age characteristics of the user from the user's consumer record.

Compared to the elderly, young people prefer to listen to pop songs, especially pop songs as the ring tones, and all mobile phone users have been young, or is at this stage, and after a large number of data mining results, the user of the choice of the song and age has a great relationship, but not linear. For example, 70 users, most like to listen to pop songs should be in 85 to 2000, that is, roughly the user at the age of 15-30. This is only a relatively common phenomenon, the actual 6184.html "> data shows that the user's song selection of the age span complex, requires a good mathematical model to extract this parameter. Hangzhou Network Company's color ring promotion system as an example, in their system, the extraction and use of age features have gone a lot of detours, only to gradually mature.

The figure below is the digital model currently used by Hangzhou Inter-network company.

Several types of users

According to the song chronological characteristics, users can be divided into several types:

First: Some users like to listen to pop songs only at a certain age, after this age, no longer listen to the songs, so the songs of other times he is not clear, such users only like a certain age of songs, such as the user's color ring library in the 85 to 95 are all published songs, such users to deal with relatively simple.

The second type: Some users, for work or other reasons, like a number of time periods of songs, such as some users of the color ring in the album of songs published in the Year (1995, 1997, 1997, 2007, 2007, 2005), such users of the song chronological characteristics of the late 90 and the recent popular.

Third: There is a class of users although the year is relatively large, but the mentality is relatively young, so all the way to listen to what the popular he listens to, this user's ring tone library song will be displayed for a large span, but is basically the most popular song every year.

Next we'll talk about how to calculate the similarity between songs.
