And is not particularly limited herein.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for pushing information in accordance with the present disclosure is shown. The method for pushing the information comprises the following steps:
step 201, for at least two information sets, setting a numerical value belonging to a first preset interval for each information in the information set.
In the present embodiment, the information in the information set may be various types of information. For example, the information may be video, audio, images, articles, and so forth. The at least two information sets may be pre-specified by a technician or may be selected according to preset selection conditions.
Optionally, the category to which each of the at least two information sets belongs may be different according to a preset category division manner. The classification manner may be determined according to actual application requirements.
For example, the information sets may be divided by the types of information in the information sets, and in this case, the at least two information sets may include an information set composed of video, an information set composed of images, and the like. For another example, the information sets may be divided according to the content of the information in the information sets, and in this case, the at least two information sets may include an information set composed of science information, an information set composed of literature information, and the like.
Of course, two or more of the division modes may be combined to divide the different categories. For example, the type and content of the information in the information sets may be combined, in which case the at least two information sets may include an information set consisting of a video of a science and technology class, an information set consisting of a video of a literature class, an information set consisting of an image of a science and technology class, an information set consisting of an image of a literature class, and the like.
In this embodiment, the first preset interval may be a value interval preset by a technician. For example, the first preset interval may be between 0 and 1.
For the information sets of the at least two information sets, the executing body (e.g., the server 105 shown in fig. 1) of the method for pushing information may set values belonging to a first preset interval for the information in each information set, respectively, so that at least two values of the values corresponding to the respective information in each information set are uniformly distributed in a sub-interval of the first preset interval.
Taking one of the information sets as an example, optionally, numerical values may be respectively set for each piece of information in the information set, so that the numerical values respectively corresponding to each piece of information in the information set are uniformly distributed in the first preset interval. In this case, generally, the numerical values corresponding to the respective pieces of information in the information set may be different.
For example, the set of information includes four pieces of information. The first preset interval is 0 to 1. Then, a value of 0.2 may be set for one of the information sets, a value of 0.4 may be set for one of the information sets, a value of 0.6 may be set for one of the information sets, and a value of 0.8 may be set for another of the information sets.
It should be understood that, when setting a numerical value for the information in the information set, the numerical value may include one or two end points of the first preset interval or may not include the end point of the first preset interval according to an actual application requirement or a requirement preset by a technician.
Still taking one of the information sets as an example, optionally, a numerical value may be respectively set for each piece of information in the information set, so that the numerical values respectively corresponding to each piece of information in the information set are uniformly distributed in the true subinterval of the first preset interval. In this case, generally, the numerical values corresponding to the respective pieces of information in the information set may be different.
For example, the set of information includes four pieces of information. The first preset interval is 0 to 1, and the true subinterval of the first preset interval is 0.5 to 1. Then, a value of 0.6 may be set for one of the information sets, a value of 0.7 may be set for one of the information sets, a value of 0.8 may be set for one of the information sets, and a value of 0.9 may be set for another of the information sets.
Still taking one of the information sets as an example, optionally, numerical values may be respectively set for each piece of information in the information set, so that partial numerical values (at least two numerical values) in the numerical values respectively corresponding to each piece of information in the information set are uniformly distributed in the first preset interval. In this case, in general, some of the values corresponding to the respective information in the information set that are uniformly distributed in the first preset interval may be different, and other values of the values corresponding to the respective information in the information set may be different, or may be partially or entirely the same.
For example, the set of information includes four pieces of information. The first preset interval is 0 to 1. Then, a third of the numerical value may be set for one of the information sets, and a second of the numerical value may be set for one of the information sets, so that the numerical values corresponding to the two pieces of information are uniformly distributed in the first preset interval. Meanwhile, any value between 0 and 1 may be set for the other two pieces of information in the information set, and the values corresponding to the other two pieces of information in the information set may be the same or different.
Still taking one of the information sets as an example, optionally, values may be respectively set for each piece of information in the information set, so that partial values (at least two values) in the values respectively corresponding to each piece of information in the information set are uniformly distributed in a true subinterval of the first preset interval. In this case, in general, some of the values corresponding to the respective information in the information set that are uniformly distributed in the first preset interval may be different, and other values of the values corresponding to the respective information in the information set may be different, or may be partially or completely the same.
For example, the set of information includes four pieces of information. The first preset interval is 0 to 1, and the true subinterval of the first preset interval is 0.5 to 1. Then, a value of two-thirds may be set for one of the information sets, and a value of five-sixths may be set for one of the information sets, so that the values corresponding to the two pieces of information are uniformly distributed in the true subinterval of the first preset interval. Meanwhile, any value between 0 and 1 may be set for the other two pieces of information in the information set, and the values corresponding to the other two pieces of information in the information set may be the same or different.
The information in the at least two information sets may be set to the corresponding numerical values in the same manner or in different manners.
For example, the at least two sets of information include a first set of information and a second set of information. At this time, corresponding values may be set for each piece of information in the first information set, so that the corresponding values of each piece of information in the first information set are uniformly distributed in a sub-interval of the first preset interval. Meanwhile, corresponding values can be set for each piece of information in the second information set respectively, so that the values corresponding to each piece of information in the second information set are uniformly distributed in the sub-interval of the first preset interval.
For another example, corresponding values may be set for each piece of information in the first information set, so that the corresponding values of each piece of information in the first information set are uniformly distributed in a sub-interval of the first preset interval. Meanwhile, corresponding values can be set for each piece of information in the second information set respectively, so that the values corresponding to each piece of information in the second information set are uniformly distributed in the true subinterval of the first preset interval.
In some optional implementation manners of this embodiment, a numerical value belonging to a first preset interval may be set for each piece of information in any one of the at least two information sets, so that the numerical values corresponding to each piece of information in any one of the information sets are uniformly distributed in the first preset interval.
At this time, for any sub-interval of the first preset interval, the ratio of the number of information in the sub-interval of the corresponding numerical value in the different information sets is close to the ratio of the number of information contained in the different information sets.
Step 202, selecting information of which the corresponding numerical value belongs to a second preset interval from an information total set consisting of at least two information sets as candidate information to obtain a candidate information set.
In this embodiment, the second predetermined interval may be a sub-interval of the first predetermined interval. The second preset interval may be preset by a technician. The information in each of the at least two information sets corresponds to a set value, and the value corresponding to each information determines the distribution condition of the value corresponding to each information in different information sets in the first preset interval, so that the value range of the value corresponding to the selected information can be directly controlled according to the application requirement, and the number of the information selected from different information sets can be controlled.
Step 203, selecting information from the candidate information set as information to be pushed, and pushing the information to be pushed.
In this embodiment, each candidate information in the candidate information set may be pushed as information to be pushed, or a part of the candidate information may be reselected from the candidate information set to be pushed as information to be pushed.
And selecting part of candidate information from the candidate information set as the information to be pushed flexibly by adopting various modes. For example, according to the attribute value of the preset attribute of each candidate information, the candidate information of which the corresponding attribute value meets the preset condition is selected as the information to be pushed.
In some optional implementation manners of this embodiment, when setting a numerical value belonging to a first preset interval for each piece of information in an information set, specifically, which piece of information in the information set corresponds to which numerical value may be randomly set. This makes it possible to make the information to be selected from the respective information sets random.
In some optional implementation manners of this embodiment, when a numerical value belonging to a first preset interval is set for each piece of information in an information set, an attribute value of a preset attribute corresponding to each piece of information in the information set may be obtained. Then, values belonging to the first preset interval may be set for each piece of information in the information set according to the attribute value of the preset attribute corresponding to each piece of information in the information set, respectively. Therefore, the information selected from each information set can be controlled not to be selected randomly but to be selected according to the attribute value of the preset attribute of each information.
The preset attribute may be an attribute that is specified in advance by a technician. For example, the preset attribute may refer to a click rate of the information, a size of the information, and the like. Therefore, the distribution situation of the numerical values corresponding to the information with different attribute values of the preset attribute in the first preset interval can be controlled, and the distribution situation of the attribute values of the selected information can be controlled conveniently.
It should be understood that, when values belonging to the first preset interval are respectively set for each information in each of the at least two information sets, different information sets may select the different setting values. For example, for some information sets, corresponding values may be randomly set for the information in the information set. For other information sets, corresponding numerical values can be set for each information according to the attribute value of the preset attribute of each information in the information set.
In some optional implementation manners of this embodiment, for one information set of the at least two information sets, after setting a numerical value belonging to a first preset interval for each piece of information in the information set, a numerical value corresponding to the piece of information may be updated for the piece of information in the information set. The difference value between the value corresponding to the information and the updated value corresponding to the information is smaller than a preset threshold value, and the updated value corresponding to the information belongs to a first preset interval. At this time, the information whose corresponding updated value belongs to the second preset interval may be selected from the information total set composed of at least two information sets as the candidate information.
Wherein the preset threshold value can be preset by a technician. In this way, the values corresponding to the respective information in the information set are approximately uniformly distributed in the first preset interval.
In some optional implementation manners of this embodiment, when setting, for each piece of information in the information set, a value belonging to a first preset interval, in response to determining that the information set is the target information set, a value belonging to a third preset interval may be set for each piece of information in the information set, so that at least two values of the values corresponding to each piece of information in the information set are uniformly distributed in the third preset interval. Wherein the third preset interval is a true subinterval of the first preset interval. In response to determining that the information set is not the target information set, values belonging to a first preset interval may be set for each piece of information in the information set, so that at least two values of the values corresponding to each piece of information in the information set are uniformly distributed in a sub-interval of the first preset interval.
Wherein the third preset interval may be preset by a technician. The target information set may also be specified in advance by a technician. For example, information sets including information in a number greater than a preset number threshold may be designated in advance as the target information set. For another example, a certain category of information set may be designated in advance as the target information set.
By setting a corresponding numerical value for the information in each of the at least two information sets in this way, different numerical value setting modes can be respectively adopted for the target information set and the non-target information set in the at least two information sets, so that the distribution situation of the numerical values respectively corresponding to the information in the target information set in the first preset interval and the distribution situation of the numerical values respectively corresponding to the information in the non-target information set in the first preset interval are differentially controlled.
Optionally, when the value belonging to the first preset interval is set for each piece of information in the information set, in response to determining that the information set is the target information set, a value belonging to a third preset interval may be set for each piece of information in the information set, so that the values corresponding to each piece of information in the information set are uniformly distributed in the third preset interval. Wherein the third preset interval is a true subinterval of the first preset interval. In response to determining that the information set is not the target information set, values belonging to a first preset interval may be set for each piece of information in the information set, so that the values corresponding to each piece of information in the information set are uniformly distributed in sub-intervals of the first preset interval.
Thus, for any sub-interval of the first preset interval, the ratio of the number of information in the sub-interval of the corresponding numerical value in different non-target information sets is close to the ratio of the number of information contained in different non-target information sets.
In any true subinterval of the third preset interval, the ratio of the number of information in the subinterval of the corresponding numerical value in different non-target information sets is close to the ratio of the number of information contained in different non-target information sets, and the ratio of the number of information in the subinterval of the corresponding numerical value in the non-target information set to the number of information in the target information set in the corresponding numerical value in the subinterval is smaller than the ratio of the number of information contained in the non-target information set to the number of information contained in the target information set.
At this time, if the information of the true subinterval of the corresponding numerical value in the third preset interval is respectively selected from each of the at least two information sets, the number of the selected information in the target information set may be greater than the number of the selected information in the target information set according to the ratio of the number of the information included in the target information set to the number of the information included in the non-target information set.
In some optional implementation manners of this embodiment, when setting a value belonging to a first preset interval for each piece of information in the information set, in response to determining that the information set includes non-candidate information, a target value may be set for each piece of non-candidate information included in the information set, and a value belonging to the first preset interval may be set for each piece of information included in the information set except for the non-candidate information. Wherein the target value does not belong to a second preset interval.
Wherein the non-candidate information may be specified in advance by a technician. Therefore, the non-candidate information can be controlled not to be selected when the candidate information set is selected by setting the numerical value outside the second preset interval for the non-candidate information.
With continued reference to fig. 3, fig. 3 is a schematic diagram 300 of an application scenario of the method for pushing information according to the present embodiment. In the application scenario of fig. 3, information set "a" 301 includes three pieces of information. Information set "B" 302 includes four pieces of information. Information set "C" 303 includes 9 pieces of information.
As indicated by reference numeral 304, for the information set "a" 301, a value of 0.25 may be randomly set for one information of the information set "a" 301, a value of 0.5 may be set for one information of the information set "a" 301, and a value of 0.75 may be set for another information of the information set "a" 301, so that the values corresponding to the three pieces of information in the information set "a" 301 are uniformly distributed over the interval of 0 to 1, respectively.
As shown by reference numeral 304, for the information set "B" 302, a value 0.2 may be randomly set for one information of the information set "B" 302, a value 0.4 may be set for one information of the information set "B" 302, a value 0.6 may be set for one information of the information set "B" 302, and a value 0.8 may be set for another information of the information set "B" 302, so that the values corresponding to the three information in the information set "B" 302 are uniformly distributed in the interval of 0 to 1.
