However, since the media information displayed at the front position is most likely to be read by the user, a higher total click rate is still obtained in the ranking cycle, so that the media information occupies the leaderboard for a long time and the news update frequency is reduced. Moreover, since some media information occupies the leaderboard for a long time and obtains a higher total click amount, the newly released media information cannot be exposed in time.

Fig. 2 is an exemplary flowchart of a media information sorting method according to an embodiment of the present invention. The method is applied to a media information sorting server in an implementation environment as shown in fig. 1. As shown in fig. 2, the method comprises the steps of:
step 201: at least one piece of media information is obtained.
In one embodiment, a media information ranking server obtains at least one piece of media information from a media information database.
Step 202: the access amount of each piece of media information is determined.
Step 203: calculating a corresponding heat value of each piece of media information according to the current cooling coefficient, the sequencing time interval and the determined access amount of each piece of media information; and sequencing the at least one piece of media information according to the heat value to obtain a media information sequencing list.
In one embodiment, determining a media information update frequency of a content category to which the at least one piece of media information belongs; determining the cooling coefficient according to the media information update frequency, wherein the heat value is calculated using the determined cooling coefficient.
In one embodiment, the heat value corresponding to the piece of media information is calculated by the following method:
H2＝H1×exp[-αT]wherein, in the step (A),
H1the access amount of the piece of stored media information;
H2calculating the heat value of the piece of media information;
alpha is a cooling coefficient;
t is the sequencing time interval.
Step 204: and when a media information acquisition request from an application server is received, sending the media information ordered list to the application server so that the application server pushes the media information according to the media information ordered list.
In one embodiment, the media information acquisition request includes an acquisition media information number N. And in the process of sending the media information ordered list to the application server, selecting the media information with the heat value arranged at the top N bits from the media information ordered list, and sending the selected N pieces of media information to the application server.
In one embodiment, after the at least one piece of media information is obtained, the current access amount of each piece of media information is obtained; and when the media information is sorted for the first time, creating an access amount list for storing the access amount of each piece of media information after acquiring the current access amount of each piece of media information. In the process of determining the access amount of each piece of media information, judging whether the access amount of the piece of media information exists in the access amount list, if so, determining the access amount of the stored piece of media information; otherwise, determining the current access amount of the currently acquired piece of media information. After the heat value corresponding to the piece of media information is calculated, the access amount list is updated by using the currently acquired current access amount of each piece of media information.
In one embodiment, in the process of obtaining the current access amount corresponding to each piece of media information, sending an access amount obtaining request to an access amount index server, where the access amount obtaining request includes the media information identifier and an access amount type, and the access amount type includes a page access amount or a user access amount, so that the access amount index server obtains the corresponding current access amount according to the media information identifier and the access amount type; and receiving the current access volume corresponding to the media information identification from the access volume index server.
Fig. 3 is an exemplary flowchart of a media information sorting method according to an embodiment of the present invention. The method is applied to the implementation environment shown in fig. 1. As shown in fig. 3, the method comprises the steps of:
step 301: the media information sorting server obtains at least one piece of media information from the media information database.
In one embodiment, the media information ranking server may periodically retrieve the media information. Then, the acquired media information is sorted, thereby realizing the periodic media information sorting.
In one embodiment, an access amount list for storing access amounts of respective pieces of media information is created at the time of first sorting.
Step 302: and the media information sorting server sends the access amount acquisition request to the access amount index server.
In one embodiment, the access amount obtaining request includes an identification of each piece of media information in at least one piece of media information obtained from the media information database and a corresponding access amount type, and the access amount type includes a page access amount or a user access amount, for example, a total click volume (PV), a number of click Users (UV). The total click rate refers to the number of times a piece of media information is clicked within a period of time, for example, the number of times a piece of media information is clicked in a sorting cycle, or the number of times the piece of media information is clicked from the publishing start to the current time. The number of users clicking is the number of independent users clicking a piece of media information within a period of time, for example, the number of independent users clicking the piece of media information in a sorting cycle of the piece of media information, or the number of independent users clicking a piece of media information from the information publishing start to the current time.
Step 303: and the access quantity index server acquires the corresponding current access quantity according to the media information identifier and the access quantity type.
In one embodiment, the current access amount refers to an accumulated access amount of the media information since the media information was published. And the access amount index server indexes the access amount corresponding to the media information through the media information identification. The access amount index server finds at least one access amount corresponding to the media information through the media information identifier, and obtains the access amount of the type through the access amount type. The access amount index server may periodically obtain an access amount log from the access amount statistics server, where the access amount log includes different types of access amounts corresponding to each piece of media information.
Step 304: and the media information sorting server receives the current access amount corresponding to the media information identification from the access amount index server.
Step 305: the media information sorting server judges whether the access quantity list contains the access quantity of the piece of media information, if so, step 306 is executed, otherwise, step 307 is executed.
Step 306: the media information sorting server determines the access amount of the stored piece of media information, calculates the corresponding heat value of the piece of media information according to the current cooling coefficient and the sorting time interval and the access amount of the stored piece of media information, and then executes step 308.
Step 307: and the media information sorting server determines the current access amount of the currently acquired piece of media information, and calculates the corresponding heat value of the piece of media information according to the current cooling coefficient, the sorting time interval and the current access amount of the piece of media information.
In one embodiment, the at least one piece of media information may belong to different content categories (e.g., international news channel, national news channel, sports channel, car channel), respectively. The information update frequency may be different for different content categories, for example, international news channel media information updates are faster, whereas automotive channel media information updates are slower. Different cooling coefficients may be set for different content categories of media information, respectively, to achieve different decay rates. As shown in fig. 4, different cooling coefficients are used to calculate the time (hours) required for the heat value of the same media information to drop from 100 to zero. When the value of the cooling coefficient x is larger, the decay of the media information heat along with the time is accelerated, and the sequencing is updated faster; when the value of the cooling coefficient x is smaller, the heat fading of the media information becomes slower, the updating of the sequence is slower, and the media information with large access quantity is arranged in the front for a longer time.
In this embodiment, the cooling coefficient is determined based on the media information update frequency, and the heat value is calculated using the determined cooling coefficient. Specifically, in order to enable the ranking of the newly released media information in the content category that is updated faster to rise quickly, a larger cooling coefficient may be set thereto so that the calculated hot value of the earlier released media information falls off faster, enabling the newly released media information to be ranked in the front faster. Conversely, for content categories that are updated more slowly, a smaller cooling factor may be set such that the calculated heat value of earlier released media information decreases more slowly, thereby ordering it longer in the front.
In one embodiment, the heat value corresponding to the piece of media information may be calculated by:
H2＝H1×exp[-αT]wherein, in the step (A),
H1the access amount of the piece of stored media information;
H2calculating the heat value of the piece of media information;
alpha is a cooling coefficient;
t is the sequencing time interval.
In one embodiment, other algorithms may be used to calculate the corresponding heat value of the media information, such as the Hacker News algorithm and the Reddit algorithm. In one embodiment, more dimensional calculation parameters may be introduced for the heat value calculation, e.g., number of reviews, reading duration, negative feedback, etc.
Step 308: and sequencing the at least one piece of media information according to the heat value to obtain a media information sequencing list.
In one embodiment, the media information belonging to different content categories is sorted according to the calculated heat value, so as to obtain a media information sorted list corresponding to each content category.
Step 309: and the media information sorting server updates the access amount list by using the currently acquired current access amount of each piece of media information.
Step 310: and when a media information acquisition request from an application server is received, sending the media information ordered list to the application server.
In one embodiment, the media information acquisition request includes an acquisition media information number N. And the media information sorting server selects the media information with the heat value arranged at the top N bits from the media information sorting list and sends the selected N pieces of media information to the application server.
In another embodiment, the media information acquisition request includes at least one content category of the media information and the number of acquired media information M corresponding to each content category. And the media information sorting server selects the media information with the top M-bit heat value from the media information sorting list corresponding to each content category included in the request, and sends the M pieces of media information corresponding to each selected content category to the application server.
Step 311: and the application server pushes the media information to the terminal equipment according to the media information ranking list.
In one embodiment, the media information may be presented on a terminal device, as shown in FIG. 5.
According to the above steps, the media server stores the current access amount of each piece of media information in each sorting process (step 309), which is used for calculating the heat value of the piece of media information in the next sorting cycle (steps 305, 306), wherein the current access amount refers to the accumulated access amount of the media information from the publishing of the media information. However, each time at least one piece of media information obtained by sorting may include media information that is first to participate in sorting, and the media information sorting server does not store the access amount of the previous cycle, at this time, the heat value may be calculated by using the current access amount (steps 305, 307). The access amount of the last sorting period is adopted, so that the influence of the burst access amount in the current sorting period on the sorting result can be avoided. For example, a piece of media information is ranked first, which results in a surge in the amount of access in the current ranking cycle. If the rapidly increased visit amount in the current sorting period is also used for heat value calculation, the influence of the time period on the sorting result is weakened, and the timeliness of news is reduced.
In the above steps, obtaining the current access amount of the media information (step 302) and calculating the heat value of the media information storing the access amount (steps 305, 306) may be performed in parallel. Specifically, when the access amount obtaining request is sent to the access amount indexing server (step 302), the media information sorting server may simultaneously determine whether there is an access amount of the piece of media information in the access amount list (step 305), and if so, the media information sorting server determines the access amount of the stored piece of media information, and calculates a heat value corresponding to the piece of media information according to the current cooling coefficient and sorting time interval and the access amount of the stored piece of media information (step 306). If it is determined that there is no access amount of the piece of media information in the access amount list, that is, the piece of media information is first taken into sorting, after receiving the current access amount corresponding to the media information identifier from the access amount indexing server (step 304), the media information sorting server calculates a heat value corresponding to the piece of media information according to the current cooling coefficient and the sorting time interval and with the current access amount of the piece of media information (step 307).
