In the accession page for determining information, information to be pushed is pushed to the user, the user does not click on the information to be pushed, the operation pair
The operating parameter answered is the first numerical value；In user in the accession page of specify information, information to be pushed has been pushed to the user,
The user clicks on and have accessed the information to be pushed, but to the information to be pushed without other behaviors, operating parameter corresponding to the operation
For second value, wherein, other behaviors can be commented on, share, thumbing up；In user in the accession page of specify information,
Information to be pushed is pushed to the user, the user is clicked on and have accessed the information to be pushed, and the information to be pushed is generated
Other behaviors, operating parameter corresponding to the operation are third value.In the present embodiment, the first numerical value, second value and
The occurrence of three numerical value is not intended as limiting, and the different interest to the information to be pushed that can be shown according to different operations are true
Fixed, for example, the first numerical value can be -1, second value can be 1, and third value can be 2.
Wherein, any one operation in above-mentioned three kinds of operations can also be divided into multiple operations, set different behaviour respectively
Make parameter, for example, in user in the accession page of specify information, information to be pushed has been pushed to the user, the user clicks on
The information to be pushed is have accessed, and other behaviors are generated to the information to be pushed, other different behaviors set different numerical value
Operating parameter.Furthermore it is possible to according to the issuable operation setting operating parameter of specific information category, for example, for example, letter
