In one possible implementation, common filtering categories include, but are not limited to: false advertisements, pornography, riots, political sensitivity, etc., which are not specifically limited by the embodiments of the present disclosure. For example, videos related to virtual advertisements, pornography, riot, political sensitivity and the like all need to be filtered.

And (3) a filtering mode: also referred to as a filtering measure or a pressing measure. Wherein the filtering means refers to performing a process on the multimedia asset representing a negative action. From another perspective, the filtering method is a specific measure for reducing the exposure of the multimedia resource. One filtering category may include at least one filtering mode.

In one possible implementation, taking a multimedia resource as an example of a video, the filtering manner may be that the video is not shown in the search result, that is, the video is not shown in the search list.

In the embodiment of the present disclosure, from a negative perspective, the filtering category is a set of multiple filtering manners. From a business perspective, the filtering category is a view of the collection of filtering modes from a business perspective. Taking the filtering category of the false advertisement as an example, firstly, the filtering category is named by the service, and secondly, the effect of the filtering category is to perform multi-aspect suppression, for example, hot spots on the false advertisement video and the false advertisement video are limited not to be shown in the search result.

Multimedia resources: in the disclosed embodiments, multimedia assets include, but are not limited to, videos, pictures, text, and the like. Taking the multimedia resource sharing platform as a short video platform as an example, the multimedia resource usually refers to a short video.

The following introduces an implementation environment related to a multimedia resource filtering method provided by the embodiment of the present disclosure.

Referring to fig. 1, the implementation environment includes: a first electronic device 101 and a second electronic device 102.

The first electronic device 101 and the second electronic device 102 are both computer devices with computing capabilities. As an example, the first electronic device 101 is a terminal, and the type of terminal includes, but is not limited to, a smartphone, a desktop computer, a laptop computer, a tablet computer, and the like. The second electronic device may appear as a server.

In the embodiment of the present disclosure, the second electronic device 102 is configured to execute the multimedia resource filtering method provided by the embodiment of the present disclosure, and the first electronic device 101 is configured to present the filtered multimedia resource to each user on the user side. As an example, the filtered multimedia resources are usually presented in the form of a service list, such as a search list, an attention list, a city list, a recommendation list, and the like, which is not specifically limited in this disclosure.

In one possible implementation, a specific application program may be installed on the first electronic device 101, and the first electronic device 101 performs data communication with the second electronic device 102 through the specific application program.

Accordingly, the first electronic device 101 only presents the short videos after the filtering process when presenting the short videos output outside the respective service list for the user.

Taking the short video sharing platform as an example, the second electronic device 102 serves the short video sharing platform for filtering the short video generated by the short video sharing platform. That is, according to the video filtering method provided by the embodiment of the present disclosure, when short videos are output to the outside through the service list, short videos related to aspects such as false advertisements, pornography, political sensitivity, riot and terrorist can be filtered out by each exposure point, and the short video sharing platform can quickly suppress exposure of illegal and illegal short videos.

A multimedia resource filtering method provided by the embodiments of the present disclosure is explained in detail below.

Fig. 2 is a flowchart illustrating a multimedia asset filtering method according to an exemplary embodiment, which is used in an electronic device, as shown in fig. 2, and includes the following steps.

In step 201, before outputting the target service list, a target multimedia resource to be processed is acquired; and inquiring in a first database according to the resource identifier of the target multimedia resource to obtain a target filtering category, wherein the first database stores the corresponding relation between the category identifier of the filtering category and the resource identifier of the multimedia resource.

In step 202, at least one filtering manner corresponding to the queried target filtering category is determined.

In step 203, when the at least one filtering manner includes a target filtering manner associated with a target service list, a filtering process is performed on the target multimedia resource according to the target filtering manner, and the target service list is used for displaying multimedia resources that are not filtered.

The method provided by the embodiment of the disclosure pre-configures the corresponding relationship between the category identifier of each filtering category and the resource identifier of the multimedia resource, and stores the configured information in the database, so that in the actual application process, before outputting a service list, it is only required to query in the database according to the resource identifier of the multimedia resource to be processed, and it can be known whether the multimedia resource corresponds to the filtering category, and when determining the corresponding filtering category, it is determined whether to perform filtering processing by using the filtering manner included in the filtering category, and the filtering manner of the multimedia resource ensures the filtering accuracy and the filtering efficiency of the multimedia resource.

and storing the category identification of the filtering category and the resource identification of the at least one item of multimedia resource into the first database by taking the resource identification of the at least one item of multimedia resource as a key and the category identification of the filtering category as a value to form a corresponding relation between the category identification of the filtering category and the resource identification of the multimedia resource. .

All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.

Fig. 3 is a flow chart illustrating a multimedia asset filtering method, as shown in fig. 3, for use in an electronic device, according to an exemplary embodiment. In a possible implementation manner, the electronic device related to the multimedia resource filtering method may include a terminal and a server. The server is responsible for filtering the multimedia resources, and the terminal at the user side is responsible for presenting the filtered multimedia resources to the user. In detail, taking a multimedia resource as an example of a video, the multimedia resource filtering process provided by the embodiment of the present disclosure includes the following steps.

In step 301, the server configures a filtering manner for each filtering category.

This step is a filtering method for configuring the filtering type.

Wherein the number and type of filtering categories may be preconfigured, in one possible implementation, the filtering categories include, but are not limited to: false advertisements, pornography, riots, political sensitivity, etc., which are not specifically limited by the embodiments of the present disclosure.

In embodiments of the present disclosure, one or more filtering modes may be configured for a filtering category. As an example, for the filtering category of the virtual advertisement, two filtering manners may be configured for the filtering category, and the two filtering manners are respectively: videos are not shown in the search results, and videos cannot be popular above.

In addition, after the filtering mode is configured for each filtering category, the configuration information can be selected to be stored in the second database. As one example, the second database may refer to a MySQL database in embodiments of the present disclosure. In a possible implementation manner, the configuration information records a corresponding relationship between the category identifier of the filtering category and the filtering manner configured for the filtering category, that is, the MySQL database stores the corresponding relationship between the two.

In step 302, for each filtering category, the server adds to the second database a video identification of at least one video matching the filtering category.

This step is to add the video primary key of the video (the object to be pressed) to the second database. The video primary key is also referred to herein as a video Identity or video ID (Identity), among others. At this point the category identification of the filtering category and the video identification of the at least one video are stored in the second database.

For a short video platform, a large number of registered users may upload a large number of short videos every day, that is, the short video platform may generate a large number of short videos every day, and the short videos may be mixed with short videos suspected of containing false advertisement content, short videos suspected of containing pornographic content, short videos suspected of containing violence and terrorist content, short videos suspected of containing political sensitive content, and the like.

In an embodiment of the disclosure, for each filtering category, the server adds to the second database a video identification of at least one video matching the filtering category. Wherein, the at least one video is the object to be pressed.

As an example, for the filtering category of false advertisements, the object to be suppressed is a short video suspected to contain false advertisement content; for the filtering category of the pornography, the suppressed object is a short video suspected to contain pornography content; for the filtering category of the riot and terrorist, the pressed object is a short video suspected to contain the content of the riot and terrorist; for the filtering category of political sensitivity, the object to be suppressed is suspected to be short video containing political sensitive content.

In addition, each filtering category corresponds to a category identification. Wherein the class identification is also referred to herein as a class primary key. In the disclosed embodiment, the category identification of the filtering category and the video identification of the corresponding object to be pressed are both stored in the second database. In another expression, the video primary key and the category primary key are stored in the second database, and if the second database is the MySQL database, for example, both the video primary key and the category primary key are stored in the MySQL database.

As an example, taking the filtering category of the false advertisement as an example, assuming that videos suspected to contain false advertisement content are video a and video B, the server stores the category key of the filtering category of the false advertisement and the video keys of the video a and the video B into the MySQL database.

In step 303, the server starts a target service to receive an event, where the event includes the category identifier of the filtering category and the video identifier of the at least one video, and the event is triggered by the second database after detecting the operation of adding the video identifier of the at least one video; the server stores the category identification of the filtering category and the video identification of the at least one video in a first database.

This step is to synchronize the category primary key and the video primary key into the first database. As an example, the first database refers to a memory database, for example, the first database is a K (Key) -V (Value) memory database such as Redis, which is not specifically limited in this disclosure.

In one possible implementation, the target service may be a piece of program code configured in advance, and the embodiment of the present disclosure also does not specifically limit this.

This step involves a publisher-subscriber schema, where the second database is the publisher and the target service is the subscriber. In the embodiment of the present disclosure, for each filtering category, the operation that the server adds the corresponding video primary key of the pressed object to the second database is sent out as an event through a Binary log (Binary log) technology, for which the server starts a target service to receive the event, and the main content of the event is the category primary key and the video primary key, so as to store the received category primary key and the video primary key in the first database.

The binary log can record the data change condition in the second database. For example, the binary log may record the addition of data, deletion of data, and modification of data in the second database. In addition, the binary log can realize master-slave copy of the database, namely, the data consistency between two databases can be realized through a Binlog technology. In accordance with the present disclosure, synchronizing the category primary key and the video primary key between the first database and the second database may be facilitated by Blilog technology.

In a possible implementation manner, taking the first database as a K-V type memory database as an example, the storing the category identifier of the filtering category and the video identifier of the at least one video into the first database includes: and storing the category identification of the filtering category and the video identification of the at least one video into a first database by taking the video identification of the at least one video as a key (K) and the category identification of the filtering category as a value (V) to form a corresponding relation between the category identification of the filtering category and the resource identification of the multimedia resource.

In summary, it is realized through the foregoing steps 301 to 303 that filtering manners are respectively configured for different filtering categories, and a binding relationship between the category primary key and the video primary key is established, wherein the binding relationship between the category primary key and the video primary key and the filtering manners configured for each filtering category are both stored in the database, so that the filtering process can be performed on the video by querying in the database, specifically refer to the following steps 304 and 305.

In step 304, before outputting the target service list, the server obtains a target video to be processed; and inquiring in a first database according to the video identifier of the target video to obtain a target filtering category, wherein the first database stores the corresponding relation between the category identifier of the filtering category and the video identifier of the video.

In the embodiment of the present disclosure, the target video to be processed is uploaded from the user, wherein the video to be but not yet subjected to the filtering process shown in step 304 and step 305 is referred to as the target video to be processed in this document.

The server may output a target service list for the service request to the terminal of the user side according to the service request initiated by the terminal of the user side. For example, if the service request is a search request, the target service list is a search list, that is, the server outputs the search list for the search request to the terminal on the user side. Before outputting the target service list to the terminal at the user side, the server may perform the filtering process shown in step 304 and step 305 on the video to ensure that only the video that is not filtered out is included in the target service list that is output to the outside in order to implement network environment purification. That is, the target service list is used to show the video that is not filtered out.

Assuming that the current server needs to output a search list externally, the search function provided by the server retrieves associated videos according to the search terms input by the user, where the associated videos refer to the target video to be processed. In the embodiment of the present disclosure, each of these associated videos belongs to an object to be filtered, and the filtering process shown in step 304 and step 305 needs to be performed. In other words, in this step, the video primary Key of the video to be filtered is used as a Key to query in the first database so as to query the filtering category corresponding to the Key. Taking the first database as a Redis database as an example, the video primary Key of the video to be filtered is used as a Key, and the filtering category corresponding to the video primary Key is inquired in the Redis database.

In step 305, the server determines at least one filtering mode corresponding to the target filtering category; and when the at least one filtering mode comprises a target filtering mode associated with the target service list, performing filtering processing on the target video according to the target filtering mode.

In the embodiment of the present disclosure, after querying the target filtering category, the server further needs to convert the queried filtering category into a specific filtering manner.

In one possible implementation manner, determining at least one filtering manner corresponding to the target filtering category includes: and searching in the filtering modes configured for each filtering type, and determining at least one filtering mode corresponding to the target filtering type. And the second database stores the filtering modes configured for each filtering type, so that at least one filtering mode of the target filtering type can be obtained by inquiring in the second database based on the type primary key of the target filtering type.

In addition, for the inquired filtering modes, the server determines whether the filtering mode related to the target service list exists. If the filter exists, the corresponding filter processing is executed, and if the filter does not exist, the filter processing is not executed. That is, only when the at least one queried filtering manner includes the target filtering manner associated with the target video service list, the server performs filtering processing on the target video according to the target filtering manner.

As an example, taking the target service as a search function as an example, it is assumed that the filtering category of the queried virtual advertisement includes two filtering manners, respectively: if the target video is not displayed in the search result and cannot be highlighted, the filtering mode matching the search function in the search result is obviously not displayed in the two filtering modes, so that the filtering processing is performed on the target video according to the filtering mode.

In step 306, the server sends the target service list to the terminal, and the terminal displays the target service list, where the target service list includes unfiltered videos.

In the embodiment of the present disclosure, in order to reduce communication consumption, the server may transmit a cover sheet, a name, and the like, such as a video, to the terminal, which is not particularly limited by the embodiment of the present disclosure. And the terminal can display the target service list at the adaptive page position. As an example, assuming that the filtered video is for a search function, that is, the target service list is a search list, the terminal may present the filtered video in a search page in the form of the search list, which is not specifically limited in this embodiment of the present disclosure.

The method provided by the embodiment of the disclosure has at least the following beneficial effects:

the method and the device for filtering the multimedia resource can pre-configure the corresponding relation between the category identification of each filtering category and the resource identification of the multimedia resource, pre-configure the filtering mode for each filtering category, and store the configured information in the database, so that in the practical application process, before outputting a service list, whether the multimedia resource corresponds to the filtering category or not can be obtained only by inquiring in the database according to the resource identification of the multimedia resource to be processed, and whether the filtering mode contained in the filtering category is adopted for filtering processing or not when the corresponding filtering category is determined, the filtering mode of the multimedia resource ensures the filtering accuracy and the filtering efficiency of the multimedia resource, further, the exposure of illegal contents on a multimedia resource sharing platform can be effectively inhibited, and the purification of a network environment is realized.

In addition, when the filtering types are newly added, the configuration is only needed to be completed according to the configuration mode, and the filtering types are not needed to be repeatedly developed once when being newly added, so that the service expansibility is enhanced. In another expression mode, even if a large number of complex services are generated due to service development requirements, the embodiment of the present disclosure can quickly support the services by only completing configuration in the database according to the configuration mode, and can be well adapted to quick iteration of the services.

In addition, a filtering mode and a resource identifier of multimedia resources are respectively configured for each filtering category, so that each filtering category also has an independent list, the filtering mode and the pressing object of each filtering category are defined, and service maintenance is facilitated.

In another embodiment, a multimedia resource filtering method provided by the embodiment of the present disclosure is exemplarily described below with reference to fig. 4.

Taking the filtering category of the false advertisements as an example, the first step is to configure the filtering mode of the filtering category of the false advertisements.

As shown in the upper left diagram of fig. 4, the filtering category of the dummy advertisement includes two specific filtering methods, which are: videos are not shown in the search results, and videos cannot be popular above. As one example, the configured information may be stored in a MySQL database.

And secondly, adding the video main keys of the videos suspected to contain the false advertisement content into a MySQL database.

As shown in the upper right diagram of fig. 4, the videos suspected of containing false advertisement content are video a and video B, respectively. The video primary keys of the video A and the video B and the category primary keys of the false advertisement filtering categories are stored in a MySQL database and are also synchronized into an in-memory database such as Redis.

And thirdly, taking a search service as an example, after searching a search result based on a search word input by a user, the search function of the server filters videos contained in the search result, wherein the video A is contained in the search result.

And fourthly, acquiring a filtering category that the video A corresponds to the false advertisement from the Redis database. The filtering type of the false advertisement and the filtering mode are converted once, the obtained video A needs to be filtered, namely the video is not shown in the search result, and therefore the video A needs to be removed when the search result is shown in the search list finally.
