Based on this, in the present exemplary embodiment, a dynamic caching method is first provided. FIG. 2 schematically illustrates a diagram of a dynamic caching method according to some embodiments of the invention. Referring to fig. 2, the dynamic caching method may include the following steps:
step S210, acquiring request information of a media side; wherein the request information includes virtual display position information of the media terminal and identification information of a user;
step S220, selecting a plurality of information to be displayed in a preset dynamic cache library according to the virtual display position information and the identification information;
step S230, filtering the multiple pieces of information to be displayed, and determining a target number of pieces of information to be displayed to adapt to the virtual display bit information;
step S240, sending the target amount of information to be displayed to the media end.
According to the dynamic cache method in the embodiment, on one hand, a plurality of pieces of information to be displayed are selected from a preset dynamic cache library, the plurality of pieces of information to be displayed are filtered and returned to a media side, a network-crossing request for an information retrieval system to be displayed is not needed, the time consumption of the information request process to be displayed is reduced, and the working efficiency of the system is improved; on the other hand, the information to be displayed updated in advance is acquired from the preset dynamic cache library, so that the timeliness of the information to be displayed is improved, and the use experience of a user is improved.
Next, the dynamic caching method in the present exemplary embodiment will be further described.
In step S210, request information of the media side is acquired; wherein the request information includes virtual presentation position information of the media terminal and identification information of the user.
In an exemplary embodiment of the present invention, the media end may refer to a terminal side that requests to acquire and display information to be displayed (for example, advertisement information displayed to a user), for example, the media end may be a WEB server, which is not particularly limited in this invention. The request information may refer to instruction information sent to an information server to be presented (e.g., ADS server) when the media end needs to present or update the information to be presented, for example, the request information may refer to a request instruction for the WEB server to request the information to be presented from the information server to be presented. The request information may include virtual show bit information of the media end, for example, the virtual show bit information may be the number of virtual show bits or attribute information; and identification information of the user, for example, the identification information of the user may be a user ID or geographical location information of the user, etc. The information server to be displayed acquires the request information of the media terminal and analyzes the request parameters contained in the request information.
In step S220, a plurality of pieces of information to be displayed are selected from a preset dynamic cache library according to the virtual display bit information and the identification information.
In an example embodiment of the present invention, the dynamic cache library may refer to a level one cache that is added by a developer between the information server to be exposed and the information retrieval system/service to be exposed. The dynamic cache library can be stored by using a memory type database and is in the same network with the information server to be displayed. The preset dynamic cache library can meet the following requirements: the corresponding information set to be displayed can be stored according to the identification information of the user; the information set to be displayed can be refreshed at regular time; the refreshing frequency of the information set to be displayed of the user can be determined according to the frequency of the information to be displayed browsed by the user.
Optionally, after the information server to be displayed acquires the request information of the media side, the request information of the media side is sent to a preset dynamic cache library; and based on the dynamic cache library, retrieving and acquiring corresponding information to be displayed through the virtual display bit information and the identification information so as to store the information in the dynamic cache library. The dynamic cache library can be a data storage structure for caching information to be displayed, can be realized through a memory database, and has short query time and high real-time performance. And the dynamic cache library retrieves and stores the information to be displayed through the virtual display bit information and the identification information in the request information, and dynamically updates the corresponding information to be displayed according to the operation data corresponding to the identification information. When the information server to be displayed receives the request information of the media terminal, the information server to be displayed corresponding to the request information can be directly obtained from the dynamic cache library. Because the information server to be displayed and the dynamic cache library are in the same network, the time consumption of the acquisition process of the information to be displayed can be shortened, and the working efficiency of the system is improved.
Specifically, before the information server to be displayed selects a plurality of pieces of information to be displayed in a preset dynamic cache library according to the virtual display bit information and the identification information, the dynamic cache library acquires timestamp information of the information to be displayed corresponding to the user when the information to be displayed is displayed at the media end through the identification information, and performs statistical calculation processing on the timestamp information to determine frequency data corresponding to the user. The history clicking operation may refer to operation information of the user browsing the presentation information on the virtual presentation position at the media end, for example, the history clicking operation may be an operation of the user clicking to enter an address link provided by the presentation information, which is not particularly limited in the present invention. And the dynamic cache library acquires the timestamp information corresponding to the historical click operation corresponding to the identification information from the storage unit of the media side through the identification information, and counts frequency data corresponding to the identification information according to the timestamp information.
Specifically, the dynamic cache library determines a priority queue of the identification information according to the frequency data based on a preset updating service; and determining the refreshing frequency of the information to be displayed corresponding to the identification information through the priority of the priority queue, and updating the information to be displayed in the dynamic cache library according to the refreshing frequency. The preset update service may refer to a preset service for updating the priority queue of the user identification information in real time, for example, the preset update service may be an advertisement update service (ADUS). The preset update service and the dynamic cache library may be deployed in the same way or separately, and the present invention is not limited to this. The refresh frequency may refer to a frequency of refreshing the information to be presented of the queue according to the priority of the priority queue, for example, the refresh frequency of the information to be presented with a higher queue priority is higher, and the refresh frequency of the information to be presented with a lower queue priority is lower. For example, the update service is provided with a user frequency cache structure, access timestamp information of a user in a preset time period (for example, 24 hours) is recorded, the access timestamp information is put into different refresh queues when exceeding a certain frequency threshold, the threshold values may be divided into TH1, TH2, TH3, …, and THn, the information refresh queues to be displayed may be divided into Q0, Q1, Q2, Q3, …, and Qn, the access times within the preset time period are lower than TH1 are put into Q0, the access times greater than or equal to TH1 and less than TH2 are put into Q1, and so on, a priority queue is determined, Q0 with the lowest refresh frequency may be refreshed at regular intervals (for example, two hours), Q1, Q2, and … Qn are sequentially halved, and specific TH values and Q0 refresh times may be set according to actual situations, which the present invention is not particularly limited.
The data structure of the update service may be shown as part of pseudo code as follows:
the data store in the data structure of the update service is divided into a hash table and a frequency queue. The hash table can be used to quickly retrieve information of a user, where the user's identification information (e.g., user id) is used as a key and the user is recorded as value. The frequency queue is divided into n queues according to the frequency data (user information can be stored in the frequency queue), wherein each queue has a corresponding update frequency interval.
In an example embodiment of the present invention, an update service in a dynamic cache library obtains, through identification information, timestamp information of information to be displayed corresponding to a user in a preset time period when the information is displayed at a media end; and performing statistical calculation processing on the timestamp information in the preset time period to determine frequency data corresponding to the user so as to update the frequency data. The preset time period may refer to data set by a developer according to an actual situation to update frequency data corresponding to a user, for example, the preset time period may be within 24 hours of the current time, and the preset time period may be adjusted in real time according to the actual situation, which is not particularly limited herein.
Specifically, the update service in the dynamic cache library judges the priority queue of the identification information according to the updated frequency data; if the index information of the priority queue of the identification information is determined to be unchanged, keeping the priority queue of the identification information unchanged; otherwise, updating the priority queue of the identification information according to the updated frequency data. For example, pseudo code for the priority queue update process is as follows:
after receiving the identification information (such as user id), the updating service queries a hash table, and takes out a history record UserHistory of user access from the hash table, wherein the timestamp of each access within a preset time period (such as 24 hours) is recorded; calculating the access times of the user in a preset time period; calling a GetQueIdx () function to obtain a frequency queue where the user information is located; deleting the access timestamp before the preset time period, and calculating a new frequency queue to which the user information should be transferred according to the access times (frequency data); if the new queue index (queue index, which may be considered as a ranking sequence number after sequencing the priority queue) is consistent with the old queue index, no queue transfer is performed (that is, no data interval corresponding to the frequent data changes, no queue transfer is performed), otherwise, the user information is deleted from the old queue and inserted into the new queue, and the update service completes the update process of the priority queue corresponding to the user information.
In step S230, a plurality of pieces of information to be displayed are filtered, and a target number of pieces of information to be displayed are determined to be adapted to the virtual display bit information.
In an example embodiment of the present invention, the filtering process may refer to a process of filtering the retrieved information to be presented by the information server to be presented. The target number may refer to the number of virtual presentation bits corresponding to the user in the media side request message.
Specifically, the information server to be displayed obtains attribute information corresponding to a plurality of pieces of information to be displayed and identification information stored in a dynamic cache library; and filtering the plurality of information to be displayed according to the attribute information, and determining the information to be displayed in the target quantity so as to enable the information to be displayed in the target quantity to be adapted to the virtual display bit information. The attribute information may refer to information corresponding to a plurality of pieces of information to be displayed and identification information for filtering the information to be displayed, for example, the attribute information may refer to information of a geographical location where a user is located corresponding to the identification information, or may refer to an inventory quantity of related products of the information to be displayed, a type of product prohibited from being displayed, and the present invention is not particularly limited thereto.
Optionally, the information to be displayed server obtains a plurality of information to be displayed stored in the dynamic cache library and a plurality of evaluation data corresponding to the information to be displayed; and sequencing the plurality of information to be displayed according to the evaluation data to determine the information to be displayed in the target quantity so as to enable the information to be displayed in the target quantity to be adapted to the virtual display bit information. The evaluation data may refer to data for evaluating the value attribute information of the information to be displayed, for example, the evaluation data may be CTR (Click Through Rate) estimation, which is not particularly limited in the present invention.
In step S240, a target amount of information to be presented is transmitted to the media side.
In an exemplary embodiment of the present invention, the information to be displayed server returns the information to be displayed of the target amount obtained by filtering in step S230 to the media side, and the media side displays the information to be displayed of the target amount on the corresponding virtual display position.
