First kind of way: determine successively weight index value for each social object in the Search Results of this object tag according to following formula:
Wherein, PR (i) is the weight index value of i social object in each definite social object of this iteration, r when i social object marking has this object tag
iBe 1, r when i social object do not marked this object tag
iBe 0, in (i) is the set of the social object of i social object of concern, out (j) is the set of the social object of j social object concern, | out (j) | be the quantity of the social object of j social object concern, pr (j) is the weight index value of the definite j of a last iteration social object, and pr (j) was the default initial weight desired value of j social object when iteration was determined for the first time, the initial weight desired value that described each social object acceptance of the bid is marked with the social object of described object tag is the first default initial weight desired value, the initial weight desired value that does not mark the social object that described object tag is arranged in described each social object is the second default initial weight desired value, and described the first initial weight desired value is greater than described the second initial weight desired value, for example, the first initial weight desired value is 1, the second initial weight desired value is 0, d is default concern transition probability, characterized after paying close attention to a social object, from the social object that this social activity object that is concerned is paid close attention to, continue the probability that the social object of selection is paid close attention to, concrete numerical value can arrange according to actual needs flexibly, for example, can be set to 0.85.
The second way: determine successively weight index value for each social object in the Search Results of this object tag according to following formula:
Wherein, PR (i) is the weight index value of i social object in definite described each the social object of this iteration, in (i) is the set of the social object of i social object of concern, out (j) is the set of the social object of j social object concern, | out (j) | be the quantity of the social object of j social object concern, pr (j) is the weight index value of the definite j of a last iteration social object, and pr (j) was the default initial weight desired value of j social object when iteration was determined for the first time, the initial weight desired value that described each social object acceptance of the bid is marked with the social object of described object tag is the first default initial weight desired value, the initial weight desired value that does not mark the social object that described object tag is arranged in described each social object is the second default initial weight desired value, and described the first initial weight desired value is greater than described the second initial weight desired value, for example, the first initial weight desired value is 1, the second initial weight desired value is 0, d is default concern transition probability, characterized after paying close attention to a social object, from the social object that this social activity object that is concerned is paid close attention to, continue the probability that the social object of selection is paid close attention to, concrete numerical value can arrange according to actual needs flexibly, for example, can be set to 0.85.
The below adopt the above-mentioned second way with instantiation to the description of giving an example of this step:
Suppose that Search Results comprises 5 social objects, be respectively U1, U2, U3, U4 and U5, and U1, U3 and U5 mark have the object tag T that is complementary with search condition, U2 and U4 have not marked this object tag T, the first initial weight desired value is 1, the second initial weight desired value is 0, and the situation of the social object paid close attention to separately of U1, U2, U3, U4 and U5 is as shown in table 3:
Table 3
Social object | The quantity of paying close attention to | The social object of paying close attention to | The social object of paying close attention to | The social object of paying close attention to |
U1 | 3 | U2 | U3 | U4 |
U2 | 2 | U3 | U4 | ? |
U3 | 2 | U1 | U2 | ? |
U4 | 1 | U3 | ? | ? |
U5 | 2 | U2 | U3 | ? |
With the first time iteration be defined as example, as follows for definite process of the weight index value of each social object of object tag T:
