Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In order to solve the technical problem that the content homogeneity of the information pushed to the user is severe and the user is tired in the prior art, an embodiment of the present disclosure provides an information pushing method, and fig. 1 is a schematic flow diagram of an information pushing method according to an exemplary embodiment. It is understood that the method can be applied to a server to form an information push platform. As shown in fig. 1, the information push method includes the following steps:
s11, the first media information with the highest score in the initial information base is obtained, and the initial information base comprises a plurality of category information, a plurality of first media information and a plurality of first mapping relations among the score information.
S12, based on the first mapping relation, the first media information with the highest score and the corresponding target category information in the initial information base are obtained.
And S13, determining a plurality of first media information corresponding to the target category information in the initial information base, and attenuating the scoring information of the first media information according to a first attenuation proportion to obtain an attenuation information base.
And S14, acquiring the first media information with the highest grade in the attenuation information base.
S15, media information is pushed to the user terminal, and the pushed media information at least comprises the acquired first media information.
For example, in step S11, it is understood that the first media information in this embodiment may be picture information, video information, text information, and the like, and the server serves as an information pushing platform, and may schedule a general information base of the pushing platform based on media information uploaded by different users or media information uploaded by a server operator, so as to be browsed by a user corresponding to the server. In order to facilitate pushing of media information, the server needs to classify the media information in the initial information base, for example, the media information is classified into movie-type media information, animation-type media information, game-type media information, food-type media information, and the like according to content presented in the media information, which is not limited in this embodiment. Meanwhile, in order to distinguish the degree of goodness of the content presented in each piece of media information, the media information may be scored according to the content of the media information, for example, the media information may be scored according to the number of praise or collection in the media information.
Optionally, referring to fig. 2, fig. 2 is a schematic flowchart of a method for acquiring an initial information base according to an exemplary embodiment, where the step S11 may further include:
and S111, acquiring a plurality of pieces of first media information according to the user portrait, wherein the first media information comprises a plurality of pieces of quantity information and identification information corresponding to the plurality of pieces of dimension information.
And S112, obtaining scoring information corresponding to the first media information based on the quantity information corresponding to the dimension information.
S113, obtaining an initial information base based on the identification information and the grading information corresponding to the first media information.
For example, in step S111, in this embodiment, the server platform has a large number of pieces of media information, the content tags of the pieces of media information are obtained by classifying the content presented in the pieces of media information, the personal preference of the user is determined by obtaining the user portrait of the user corresponding to the user terminal, and the corresponding content tags are searched on the server platform according to the personal preference of the user, so as to obtain a plurality of pieces of first media information corresponding to the personal preference of the user. It can be understood that, in order to characterize the heat of the media information to the user and facilitate the user to discriminate, the data of different dimensions in the media information are usually counted, and the counted quantity information is displayed to the user. It can be understood that the identification information in the media information is used to indicate an identity category of the media information and to identify an affiliation of the media information, and for example, the media information may be classified according to a company associated with the media information, which is not limited in this embodiment.
In step S112, summing the quantity information corresponding to the obtained dimension information to obtain the rating information corresponding to each first media information, for example, taking the dimension information as an example, the quantity information corresponding to the obtained dimension information is the number of comment information pieces, the number of praise and the number of forwarding, and summing the quantity information to obtain the rating information corresponding to the first media information.
Optionally, the step S112 may further include:
and acquiring a plurality of feature weights corresponding to the dimension information.
And calculating a plurality of quantity information corresponding to the plurality of dimension information according to a preset algorithm based on the plurality of characteristic weights to obtain scoring information.
It can be understood that, when the media information is evaluated, in order to make the evaluation information of the representation more accurate, a weight needs to be set for the quantity information corresponding to the different dimension information, for example, the contribution degree of the praise quantity to the evaluation can be set to be weak, so that the quantity information corresponding to the praise dimension occupies a smaller proportion, the contribution degree of the forwarding dimension to the evaluation can be set to be stronger, and thus the quantity information corresponding to the forwarding dimension occupies a larger proportion.
For example, after determining the influence degree of the plurality of pieces of quantity information on the rating information according to the feature weight corresponding to the dimension information, the quantity information corresponding to the plurality of pieces of dimension information is multiplied by the corresponding feature weight, and the obtained quantities are added to obtain the rating information corresponding to the media information. For example, the number of praise corresponding to the acquired media information is 65798, the number of comment information pieces is 18457, the forwarding number is 6547, and the feature weights of three dimensions of praise, comment and forwarding are 0.45%, 0.1% and 0.6%, respectively, then the score information corresponding to the media information is 95% after the weighted sum calculation.
In step S113, after obtaining the rating information corresponding to each piece of media information through the above steps, a corresponding mapping relationship may be established according to the identification information and the rating information corresponding to the piece of media information, so as to form an initial information base, for example, category information may be set as a company associated with the piece of media information, and a first mapping relationship may be established according to the following initial information base table, where the initial information base table is:
it is understood that, in step S12, according to the first mapping relationship among the category information, the media information, and the rating information in the initial information base, the first media information and the category information corresponding to the highest rating information, and other media information under the affiliated category information are determined, and the corresponding category information is taken as the target category information, for example, in the above-mentioned initial information base table, if the query rating information determines 97-bit highest rating, the corresponding first media information is media information 5, and the corresponding target category information is company B.
For example, in step S13, it is understood that after the first media information that can be pushed to the user terminal is acquired through the above steps, the server needs to further filter other media information, so as to implement continuous pushing for the user. Generally, most of the scoring information of the media information in the same category is similar, which results in that most of the media information with high scoring belongs to the same category, and if the first media information is obtained by the method for obtaining the media information corresponding to the highest scoring information, a plurality of media information pushed to the user belong to the same category, which results in that the media information received by the user has high repeatability. Therefore, after the first media information and the target category information corresponding to the highest-score information are acquired through the above steps, in order to avoid selecting other media information under the same category for multiple times, meanwhile, in order to avoid the first media information corresponding to the highest score in the initial information base obtained through the above steps from being selected again, it is necessary to set a first attenuation ratio for the score information corresponding to the plurality of media information under the target category information, thereby obtaining the attenuation information base corresponding to the latest grading information, for example, the first attenuation ratio can be set to be 0-0.8, wherein 0 is the attenuation ratio corresponding to the first media information with the highest score in the initial information base, and 0.8 is the attenuation ratio corresponding to other media information except the first media information in the target category information, and the following attenuation information base table is obtained by taking the initial information base table as an example:
it is to be understood that, in step S14, the highest-scoring media information in the decay information base is determined as the second first media information, for example, the decay information base table as described above, and the highest-scoring media information at this time is determined as the second first media information, i.e., the media information 2.
For example, in step S15, after the two pieces of first media information are obtained through the above steps, that is, the first media information corresponding to the highest scoring information in the initial information base and the first media information corresponding to the highest scoring information in the attenuation information base, and the obtained first media information is pushed to the user terminal, for example, the order of pushing to the user terminal may be to determine the scoring information corresponding to the two pieces of first media information first, and compare the two pieces of scoring information, and push the two pieces of scoring information to the user terminal as the pushing order. It can be understood that, in this embodiment, for a single piece of displayed media information, for example, video information, the push sequence at this time may be a transmission sequence sent by the server to the user terminal, for example, taking the initial information base table and the attenuation information base table as an example, if the first media information corresponding to the initial information base is media information 5, the first media information corresponding to the attenuation information base is media information 2, the score value corresponding to the media information 5 is 97, and the score value corresponding to the media information 2 is 96, the server sequentially sends the media information 5 and the media information 3 to the user terminal, and the user terminal browses the media information 5 first and then browses the media information 3 based on a sliding operation. Optionally, for media information that can be displayed in multiple ways in the same user interface, such as picture information, article information, and the like, the pushing sequence at this time is a typesetting sequence on the user display page, taking the pushing sequence as an example, the display sequence is the media information 5 arranged at the most prominent position, and the media information 3 arranged at the secondary prominent position, which is not limited in this embodiment.
Optionally, the step S15 may further include:
and under the condition that the acquired first media information does not reach the first specified quantity, the attenuation information base is used as the initial information base again, and the steps from acquiring the target category information corresponding to the first media information with the highest score in the initial information base to acquiring the first media information with the highest score in the attenuation information base based on the mapping relation are repeatedly executed until the acquired first media information reaches the first specified quantity.
And under the condition that the obtained first media information reaches a first specified number, sequencing the obtained first media information based on the grading information in the attenuation information base to obtain a pushing sequence.
And pushing the acquired first media information to the user terminal according to the pushing sequence.
It can be understood that, when the server pushes information to the user terminal, the server generally pushes the information in the form of a feed stream, and the feed stream provides a certain amount of media information to the user based on one-time refresh behavior of the user, so that the server generally contains a plurality of media information when preparing to push information for the user terminal, and therefore, after two first media information are obtained through the above steps S11-S14, the obtained amount of the first media information is compared with a preset first specified amount, and when the amount of the first media information fails to reach the first specified amount, the attenuation information base is taken as a new initial information base to repeat the above steps S11-S14 until the obtained amount of the first media information reaches the preset first specified amount. For example, when the first designated number is 10, the above steps of S11-S14 need to be repeated 5 times to obtain 10 different-scoring first media information.
Illustratively, after a plurality of first media information of a first specified number are acquired through the above steps, according to the rating information corresponding to the first media information extraction, a pushing sequence for pushing the media information to the user terminal is determined according to the height sequence of the rating information, and the corresponding media information is pushed to the user terminal according to the pushing sequence.
Optionally, the step S15 may further include:
and S151, acquiring a heat degree information base based on the current time, wherein the heat degree information base comprises a second mapping relation between a plurality of second media information and a plurality of heat degree scores.
S152 acquires one or more second media information in the hotness information base.
S153 ranks the acquired first media information and one or more second media information according to a preset ranking rule based on the rating information in the heat rating and attenuation information base, so as to obtain a push order.
S154, sequencing the acquired first media information according to the pushing sequence and pushing one or more second media information to the user terminal.
Referring to fig. 3, fig. 3 is a flowchart illustrating another information pushing method according to an exemplary embodiment, it may be understood that, in step S151, to further enrich media information pushed to a user terminal, so as to enrich types covered by the media information in a feed stream, a server may obtain, according to a current time, a plurality of pieces of hotness information with highest hotness in the server at that time as a plurality of pieces of second media information, for example, the hotness score at that time may be evaluated according to an accumulated click volume of each piece of media information in the server at the current time, the higher the accumulated click volume of the user is, the higher the hotness score is, and a second mapping relationship between each piece of hotness information and the hotness score is established according to the hotness score corresponding to the second media information. It is worth mentioning that, in addition to the click amount, the popularity score may be calculated based on other dimensions, such as the number of comment information pieces, the number of likes and the number of forwards, or may be collectively evaluated based on the click amount, the number of comment information pieces, the number of likes and the number of forwards.
It is to be understood that, in step S152, one or more pieces of second media information with the highest scores in the popularity information base are determined according to the second mapping relationship, and for example, when the number of pieces of second media information in the popularity information base needs to be extracted is 10, 10 pieces of second media information with the top scores of 10 are obtained according to the second mapping relationship.
It is understood that, in step S153, after the plurality of first media information are acquired through the above steps S11 to S12, and after the one or more second media information are acquired through the above steps S151 to S152, at this time, the media information that needs to be pushed to the user in the server has been filtered, and the acquired plurality of first media information and the acquired second media information need to be sorted, so that the server can complete pushing of the media information.
Optionally, the step S153 may further include:
the acquired first media information is sorted based on the scoring information in the decay information base.
One or more second media information is arranged between the first target information and the second target information to obtain a push order. The first target information is the first media information with the highest grade in the initial information base, and the second target information is the first media information with the highest grade in the attenuation information base.
For example, in step S153, according to the score information corresponding to the first media information, the plurality of first media information may be sorted in a descending order, according to the popularity score information corresponding to the second media information, the second media information (at this time, if the second media information is a plurality of second media information, the second media information is directly extracted if the second media information is a single second media information) may be sorted in a descending order, and the second media information is inserted into the sequence of the first media information in order, so that the first media information in the first media information is not adjacent to each other, thereby obtaining the push order.
Illustratively, in step S154, according to the obtained pushing sequence in the above steps, the obtained first media information and second media information are sequentially pushed to the user terminal, so that when the user browses information, the information types are richer, the repeated information is less, and the user experience is improved.
Optionally, referring to fig. 4, fig. 4 is a schematic flowchart of another information pushing method according to an exemplary embodiment, where the step S15 may further include:
s155 obtains a popularity information base based on the current time, where the popularity information base includes mapping relationships between a plurality of second media information and a plurality of popularity scores.
S156 acquires one or more second media information as hit information based on the popularity information base.
S157 selects a first preset number of first media information from the acquired first media information according to a preset extraction ratio, and selects a second preset number of second media information from the hot information, where a sum of the first preset number and the second preset number is a second designated number.
S158 ranks the first media information of the first preset number and the second media information of the second preset number based on the rating information and the popularity rating in the attenuation information base, so as to obtain a push sequence.
S159, pushing the first media information of the first preset number and the second media information of the second preset number to the user terminal according to the pushing sequence.
For example, since the first media information in the initial information base is the first media information associated with the personal preference of the user, which is obtained according to the user portrait of the user, it can be understood that, in order to enrich the content of the media information pushed to the user, other information bases can be obtained according to other filtering dimensions, and in this embodiment, the second media information with higher heat degree at the current time is obtained as the heat degree information base.
It can be understood that, for the plurality of information bases, the weight of the media information to be extracted in each information base may be set as a preset extraction ratio according to the type weight of the media information to be pushed to the user, and then the corresponding amount of the first media information and the second media information is extracted from the highest score to the lowest score according to the first preset amount and the second preset amount in the heat information base and the attenuation information base respectively according to the above extraction methods, and the plurality of first score information and the plurality of second score information are sorted according to the score information and the heat score information of the first media information and the second media information, for example, the push order may be obtained by the above random sorting method, and then the corresponding first media information and second media information are sent according to the push order, for example, the preset extraction ratio may be set to be 7: 3, if the second designated number is 10, then 7 different pieces of first media information are obtained in the attenuation information base according to the selection mode in the steps S11-S12, 3 pieces of second media information with the highest popularity scores are selected in the popularity information base, and then the 7 pieces of first media information and the 3 pieces of second media information are pushed to the user terminal according to a random sorting method. For example, for a user with less user data corresponding to less user favorite types in the user representation, when the media information in the initial information base obtained by the method cannot reach a first preset number, the first media information is supplemented by the second media information, so that the number of the pushed media information reaches a second specified number.
Optionally, the information pushing method may further include:
and if the target scoring information smaller than the first preset scoring threshold exists in the attenuation information base, deleting the target scoring information, the first media information corresponding to the target scoring information and the category information.
It can be understood that, based on each refreshing behavior of the user, the media information in the initial information base is filled once, and after multiple information pushing and score information attenuation, the score information is not selected by the server when reaching a certain value, and in order to save storage space, when the target score information reaches a threshold value, the target score information and the corresponding media information are deleted from the server.
Optionally, the method further comprises:
attenuating the scoring information in the attenuation information base based on the second attenuation proportion under the condition that the preset condition is reached;
and if the target scoring information smaller than the second preset scoring threshold exists in the attenuation information base, deleting the target scoring information, the first media information corresponding to the target scoring information and the category information.
