(4) system timestamp set: splay: [ T ]1，T2，…，TN]Wherein, TNAnd the system time stamp of the Nth target account from the starting of the client to the playing of the multimedia is shown. The system time stamp may be in units of days, seconds, or the like.
For example, the system timestamps corresponding to the target account from the client to the time of playing the multimedia are 1 month, 1 day, 10:00, 1 month, 1 day, 10:05, and 1 month, 1 day, 15:00, and at this time, the system timestamp set Splay is: [1 month 1 day 10:00, 1 month 1 day 10:05, 1 month 1 day 15:00 ].
And step S204, determining the interest index of the target account on the target multimedia set according to the time information and the updating period.
Optionally, in the embodiment of the present application, in combination with time information in the system timestamp set and a multimedia update period, an interest index of the target account with respect to the target multimedia set is determined, and whether the target account is continuously interested in the target multimedia set is obtained according to the interest index, where the continuous interest is used to indicate a degree of interest of the target account in a subsequent update stage of the target multimedia set.
In the embodiment of the application, by adopting a mode of determining an interest index of a target account on a target multimedia set, acquiring an identity identifier of the target account and an identifier of the target multimedia set, wherein the target multimedia set comprises a plurality of multimedia; acquiring multimedia playing behavior data corresponding to the identification of the target multimedia set under the identification and an updating period of multimedia in the multimedia set according to the identification of the identification and the identification of the target multimedia set, wherein the multimedia playing behavior data is behavior data of a plurality of multimedia in the target multimedia set by a target account; determining time information for playing the multimedia in the multimedia set according to the multimedia playing behavior data; and determining the interest index of the target account to the target multimedia set according to the time information and the updating period. Since the present application analyzes the multimedia playing behavior data executed by the target account on at least one multimedia in the target multimedia set, by recording the corresponding multimedia time information when the multimedia playing behavior data is executed, obtaining the interest index of the target account for watching the target multimedia set by using the multimedia time information and the multimedia updating period, judging whether the target account continuously catches up with the target multimedia set by using the interest index, the recommendation reference parameter is used as the recommendation reference parameter of the target multimedia set related advertisement and commodity program information, thereby improving the recommendation accuracy of the enterprise related recommendation system, and then the aim of larger revenue is achieved, and the problem that the recommendation accuracy is low because some multimedia information which is interesting to the user and can be continuously watched cannot be recommended according to the watching interest index of the user in the related technology is solved.
As an alternative embodiment, determining the interest indicator of the target multimedia set in the target account according to the time information and the update period includes:
according to the time information, obtaining a stability value of the target multimedia set played by the target account;

As an optional embodiment, obtaining the stability value of the target multimedia set played by the target account according to the time information includes:
under the condition that the number of the time information is determined to be larger than or equal to a preset value, obtaining a difference value between two adjacent time information to obtain a plurality of interval difference values;
obtaining the mean value of the interval difference values;
obtaining a standard variance value by using the mean value and a plurality of interval difference values;
and determining the standard deviation value as a stability value, wherein the standard deviation value is used for representing the stability of the target multimedia set played by the target account.
Optionally, when the number of the time information in the system timestamp set is greater than or equal to a preset value, obtaining a difference between two adjacent time information before and after obtaining a plurality of interval differences, where the preset value is a self-defined value, and usually the value should be greater than or equal to 2, so that at least one interval difference can be obtained.
In addition, since the system timestamp set Splay can be expressed as: [ T ]1，T2，…，TN]At this time, the calculation formula of the difference between the two previous and next playing intervals is: delta TN-1＝TN–TN-1An interval difference set S Δ T can be obtained: [ Delta T1，…，ΔTN-1]。
Then, calculating a mean value of the interval difference values, namely a mean value of the interval difference value set S delta T: delta Targ＝(ΔT1+…+ΔTN-1)/(N-1)。
Using Δ TargAnd a plurality of interval differences, calculating a standard deviation value:
and obtaining the stability of the target multimedia set played by the target account according to the standard variance value sigma. Specifically, when the time data distribution is comparatively dispersed (i.e., the time data fluctuates largely around the mean), the sum of squares of differences between the respective time data and the mean is large, and the standard deviation value after arithmetic square root is large; when the data distribution is more concentrated, the sum of squares of the differences of the respective time data and the mean value is smaller. Therefore, the larger the standard deviation value is, the larger the fluctuation of the time data is, and the worse the stability of the target multimedia data set is; the smaller the standard deviation value, the smaller the fluctuation of the time data and the higher the stability of the target multimedia data set.
In the embodiment of the application, the standard variance value is obtained by calculation according to the interval difference value and the interval difference value mean value obtained by time information, and the stability value of the target multimedia set obtained according to the standard variance value is more accurate.

Wherein the first preset threshold is a mean value Delta T of interval difference values among a plurality of time informationargDetermined, in particular, a first preset threshold σvalidCalculating the formula: sigmavalid＝ΔTargWhere M is an empirical reference value, is a custom value, and can be adjusted as appropriate, so that the first predetermined threshold σ is determinedvalidAt a value of Δ TargWhen the value is determined, the value of M is adjusted.
The second preset threshold is calculated from all historical multimedia corresponding to the identification of the target account, specifically, a historical multimedia frequency average of all historical multimedia is calculated, and the historical frequency average is determined as the second preset threshold.
