Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes the content filtering method and apparatus provided by the embodiments of the present invention in detail with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1, a content filtering method provided in an embodiment of the present invention includes:
101. group content and a group identification (group ID) provided by a content filtering requester are received.
The content filtering requester may be an entity that initiates a content filtering request to a content filtering server during an actual network transmission process, such as BCAST (Open Mobile Alliance Mobile Broadcast Service enabled Suite, Mobile Broadcast Service engine of Open Mobile Alliance)/BCMCS (Broadcast and Multicast Service), and other Broadcast Multicast content providers, distributors, and the like;
the group content refers to content for users in a group, which can be transmitted by multicast or broadcast.
102. And performing primary filtering on the group content.
For filtering group content, a content filtering server generally filters the group content according to a common filtering rule, and then transmits a filtering result to a user in a multicast or broadcast manner. In the present invention, in addition to the filtering of the group content by the content filtering server, the content filtering is performed once on the user terminal side, so the content filtering process performed by the content filtering server is referred to as primary filtering, and the content filtering process performed by the terminal side is referred to as secondary filtering.
When the group content is primarily filtered, the group content may be primarily filtered according to a general filtering rule for all users and/or a group filtering rule for group users. Depending on the general filtering rules and/or the group filtering rules, some corresponding operations may be performed, such as: the general filtering rules and/or the group filtering rules relate to filtering rules based on categories, and the categories need to be determined firstly; the determination of the category may be by external acquisition, local matching, or classification using some algorithm. The following steps are repeated: if the generic filtering rules and/or the group filtering rules relate to some external information such as: age, sex, etc., it is first obtained from the outside.
If all or part of the group content passes the primary filtering after the primary filtering, continuing to execute steps 103, 104 and 105; if all the contents of the group contents do not pass the primary filtering, only step 104 needs to be executed after step 102 to terminate the content filtering process.
103. And under the condition that all or part of the group content passes the primary filtering, determining a secondary filtering strategy aiming at each user in the group corresponding to the group identification.
In the primary filtering process, if no group content can pass the primary filtering, the content filtering server can directly feed back the filtering result, and meanwhile, the user terminal side does not need to carry out secondary filtering; as long as there is still part of the group content passing the primary filtering after the primary filtering, a subsequent secondary filtering is required at the user terminal side. That is, in the case that all or part of the group content passes the primary filtering, it is necessary to determine a secondary filtering policy for the user as a basis for the secondary filtering.
According to the group ID, the member information of the group can be obtained from a local or special user information server, wherein the content filtering rule of each user is recorded; further, according to the content filtering rule corresponding to each user, determining a secondary filtering strategy of each user in the group corresponding to the group ID.
The secondary filtering strategy obtained by step 103 includes: a content reference corresponding to the initially filtered group content, and a filtering indication for the initially filtered group content.
104. And returning the primary filtering result after primary filtering to the content filtering requester.
In this step, the primary filtering result may be: the content that passes after the initial filtering, and/or various filtering operation instructions that need to be performed on the group content, such as: the content should be blocked, the content should be blocked and a prompt message should be sent to the user, the content passes without modification, or the content passes without deletion of a picture, etc.
105. And sending the secondary filtering strategy to a user terminal.
In the description of the above method, the execution subject of each step may be a content filtering Server based on classification (CBCS Server); meanwhile, the codes corresponding to the steps are not used for limiting the specific execution sequence, and may be adjusted as needed in the actual execution process, for example, step 104 may be executed before step 103, or step 104 and step 105 may be executed in parallel.
Corresponding to the content filtering method, the embodiment of the invention also provides a content filtering server; as shown in fig. 2, the content filtering server includes:
a receiving unit 21, configured to receive group content and group identifier provided by a content filtering requester;
a filtering unit 22, configured to perform primary filtering on the group content;
a determining unit 23, configured to determine, when all or part of the group content passes the primary filtering, a secondary filtering policy for each user in a group corresponding to the group identifier;
a first sending unit 24, configured to send the primary filtering result after the primary filtering to the content filtering requester;
and a second sending unit 25, configured to send the secondary filtering policy to the user terminal.
In the embodiment of the invention, the content filtering server performs preliminary filtering on the group content, a content filtering strategy for each user in the group is formulated through the content filtering server, and then the content filtering strategy is issued to the corresponding user terminal, so that the user terminal can complete secondary content filtering for specific users according to the content filtering strategy; the scheme provided by the embodiment of the invention can realize the group content filtering according to the requirement of each user, and meet the accurate requirements of different users on the group content filtering.
Example two:
as shown in fig. 3, another content filtering method provided in the embodiment of the present invention includes:
301. group content and group identification provided by a content filtering requester are received.
The content filtering requester may be an entity that initiates a content filtering request to a content filtering server during actual network transmission by BCAST/BCMCS and other broadcast multicast content providers, distributors, etc.;
the group content refers to content for users in a group, which can be transmitted by multicast or broadcast.
302. And performing primary filtering on the group content.
When the group content is primarily filtered, the group content may be primarily filtered according to a general filtering rule for all users and/or a group filtering rule for group users.
Depending on the general filtering rules and/or the group filtering rules, some corresponding operations may be performed, such as: the generic filtering rules and/or the group filtering rules relate to category-based filtering rules, which require a prior determination of the category. The following steps are repeated: if the generic filtering rules and/or the group filtering rules relate to some external information, such as: age, sex, etc., it is first obtained from the outside.
If all or part of the group content passes the primary filtering after the primary filtering, continuing to execute the steps 303 and 304; if all the contents of the group content do not pass the primary filtering, only the primary filtering result after the primary filtering needs to be returned to the content filtering requester after the step 302 and the flow of content filtering is terminated.
303. Determining a content category to which the group content after the primary filtering belongs if all or part of the group content passes the primary filtering.
In the primary filtering process, if no group content can pass the primary filtering, the content filtering server can directly feed back the filtering result, and meanwhile, the user terminal side does not need secondary filtering; as long as there is still part of the group content passing the primary filtering after the primary filtering, a subsequent secondary filtering is required at the user terminal side.
That is, when all or part of the group content passes the primary filtering, the content category to which the group content that has passed the primary filtering belongs needs to be determined as a basis for the secondary filtering.
304. And sending the primary filtering result after the primary filtering and the content category to the content filtering requester.
The presentation forms of the primary filtering results are different according to different user requirements or different filtering strategies adopted by different content filtering servers. In this step, the primary filtering result may be: the content that passes after the initial filtering, and/or various filtering operation instructions that need to be performed on the group content, such as: the content should be blocked, the content should be blocked and a prompt message should be sent to the user, the content passes without modification, or the content passes without deletion of a picture, etc.
In the description of the above method, the execution subject of each step may be a content filtering Server based on classification (CBCS Server); meanwhile, the codes corresponding to the steps are not used for limiting the specific execution sequence, and can be adjusted according to needs in the actual execution process.
Corresponding to the content filtering method, the embodiment of the invention also provides a content filtering server; as shown in fig. 4, the content filtering server includes:
a receiving unit 41, configured to receive the group content and the group identifier provided by the content filtering requester;
a filtering unit 42, configured to perform primary filtering on the group content;
a classifying unit 43, configured to determine a content category to which the group content subjected to the primary filtering belongs if all or part of the group content passes the primary filtering;
a first sending unit 44, configured to send the primary filtering result after the primary filtering and the content category to the content filtering requester.
In the embodiment of the invention, a content filtering server performs primary filtering on group content, and determines content categories corresponding to all or part of the group content which passes the primary filtering through the content filtering server under the condition that all or part of the group content passes the primary filtering, and then returns the content categories to a content filtering requester so as to perform secondary filtering on the group content which is subjected to the primary filtering in the following process; the scheme provided by the embodiment of the invention can realize the group content filtering according to the requirement of each user, and meets the accurate requirements of different users on the group content filtering.
Example three:
as shown in fig. 5, a method for content filtering provided in an embodiment of the present invention includes:
501. and receiving the primarily filtered group content.
The group content after the initial filtering refers to the group content which passes through after the initial filtering is carried out according to the general filtering rule and/or the group filtering rule.
502. And acquiring a secondary filtering strategy corresponding to the group content after primary filtering.
The secondary filtering policy is provided by the content filtering server and is specific to the group content received by the current user terminal. Specifically, the secondary filtering policy may be issued actively by the content filtering server, or may be requested by the local terminal to obtain the secondary filtering policy from the content filtering server under the condition that the secondary filtering policy is not stored locally; if the secondary filtering strategy is stored locally, the secondary filtering strategy pre-stored locally can be directly read.
503. And filtering the content of the group content after the primary filtering according to the secondary filtering strategy.
The secondary filtering strategy records an indication for a certain type of content or filtering for a certain type of content, so that the primarily filtered group content can be secondarily filtered according to the indication. For example, if the current user is a student, the group content received by the student that is related to "games" may be filtered out altogether; for another example, according to the requirement of a certain user, the content received by the user, which contains the word "promotion", is filtered out.
The main body for executing the above steps may be a user terminal that needs content filtering, or a content filtering client integrated in the user terminal, such as a CBCS client.
Corresponding to the content filtering method, the embodiment of the invention also provides a terminal for filtering the content; as shown in fig. 6, the terminal includes:
a receiving unit 61, configured to receive the group content after the primary filtering;
an obtaining unit 62, configured to obtain a secondary filtering policy corresponding to the group content after the primary filtering;
and a filtering unit 63, configured to perform content filtering on the group content after the primary filtering according to the secondary filtering policy.
In the embodiment of the invention, the user terminal performs secondary content filtering on the group content which passes the primary filtering according to the content filtering strategy which is provided by the content filtering server and aims at each user in the group; therefore, the purpose of filtering the group content according to the requirements of each user is achieved, and the accurate requirements of different users on the group content filtering are met.
Example four:
the content filtering method provided in the embodiment of the present invention is further described below with an embodiment.
As shown in fig. 7, the method for filtering content in the embodiment of the present invention specifically includes the following steps:
701. and the content filtering requester sends the group content and the group ID to a content filtering server and requests the content filtering server to filter the content of the group content.
The content filtering requester may be an entity that initiates a content filtering request to a content filtering server during actual network transmission by BCAST/BCMCS and other broadcast multicast content providers, distributors, etc.;
the group content refers to content for users in a group, which can be transmitted by multicast or broadcast.
The group ID is not included in the existing content filtering request, so in this embodiment, the group ID may be carried in the following manner:
<xs:element name＝″userInformation″>
<xs:complexType>
<xs:attribute name＝″userInformationType″type＝″xs:string″/>
</xs:complexType>
</xs:element>
wherein, attribute can be assigned to GroupID and UserInformation can be assigned to group ID.
702. After identifying that the currently received group content is a filtering request aiming at the group content through the group ID, the content filtering server carries out primary filtering on the received group content according to a general filtering rule and/or a group filtering rule to obtain a primary filtering result; in the primary filtering process, the specific used general filtering rule or group filtering rule may be determined by the setting in the content filtering server.
The filtering rules may be corresponding processing for different types of content, for example: the advertisement content can be directly filtered; alternatively, the content containing some kind of keywords may be processed correspondingly, for example: the content containing fields such as 'game' or 'promotion' can be directly filtered out; it is of course also possible to perform content filtering based on other conditions, such as refusal of receiving entertainment messages during working hours, filtering based on age, etc. If the content filtering server does not store or receive information required for such filtering, such as the above-mentioned category (advertisement category), age, etc., it is necessary to determine the category first or to acquire age information from the outside first. Wherein the determination of the category may be external acquisition, local matching, or classification using some algorithm, etc.
Wherein the common filtering rule is a filtering rule for all content filtering operations for all users; the group filtering rule is a filtering rule facing a certain group, and the content sent to all users in the group must be followed by the filtering rule.
703. If all or part of the group content passes the filtering in step 702, the content filtering server obtains the member information in the group corresponding to the group ID according to the group ID, then obtains the content filtering rule of each user according to the member information, and performs content filtering on the content which has passed the primary filtering according to the content filtering rule of each user, and generates a secondary filtering strategy for each user; the secondary filtering strategy obtained at this time includes: a content reference (content reference) corresponding to the primarily filtered group content, and a filtering indication for the primarily filtered group content.
The member information in the group and the content filtering rule of each user can be preset by the user and stored on the content filtering server or a server of special user information; the member information in the group and the content filtering rules of each user may be stored in the same server or different servers.
The content filtering rule of each user refers to the filtering requirement of each user on the content.
In this step, when filtering the primary filtering result according to the content filtering rule of each user, the content filtering server records the group content after primary filtering and the filtering indication for the group content after primary filtering, that is, the specific processing modes such as allowing, blocking, shielding or deleting are allowed; meanwhile, a content reference (content reference) corresponding to the group content after the primary filtering is generated.
Wherein, the rule for generating the content reference needs to be set in advance, or the rule for generating the content reference is specified in a message requesting filtering in a well-agreed manner; for example, the content reference corresponding to the group content after the initial filtering may be an information summary of the group content after the initial filtering, and may also be some other parameters that may be used to identify the group content after the initial filtering, such as: URI (universal Resource Identifier) address.
If the group content in step 702 is totally blocked and not sent to the user, step 703 is skipped and the process is terminated after step 704 is completed.
704. And the content filtering server returns the primary filtering result to the content filtering requester.
705. And the content filtering requester sends the primarily filtered group content to the user terminal.
The content filtering requester may issue the group content after the initial filtering through a broadcast or multicast channel, or may send the group content after the initial filtering through other methods.
The group content subjected to the initial filtering may be directly received group content subjected to the initial filtering, or may be group content processed according to a received filtering operation instruction, such as: deleting some contents on the basis of the original contents, adding user prompts and the like.
706. And the content filtering server sends the secondary filtering strategy to the user terminal.
In this step, the secondary filtering policy may be actively sent to the user terminal by the content filtering server, or may be actively requested by the user terminal to obtain the secondary filtering policy from the content filtering server after receiving the group content subjected to the primary filtering.
707. And the user terminal filters the content of the group content after the primary filtering according to the secondary filtering strategy.
Specifically, the content filtering client located on the user terminal first identifies the group content corresponding to the content reference according to the content reference, and then performs content filtering on the identified group content according to the filtering instruction.
In the description of the above method, the number of each step is not used to limit the execution order thereof; for example, step 704 may be performed prior to step 703, and steps 704, 705 may be performed in parallel with step 706.
In the embodiment of the invention, a content filtering server performs primary filtering on group content, a secondary filtering strategy aiming at each user in a group is formulated through the content filtering server, the secondary filtering strategy comprises content quotes corresponding to the group content after primary filtering and filtering instructions aiming at the group content after primary filtering, then the secondary filtering strategy is issued to a corresponding user terminal, and the user terminal completes secondary content filtering aiming at specific users according to the secondary filtering strategy;
by the scheme provided by the embodiment of the invention, the group content can be filtered according to the requirement of each user, and the accurate requirements of different users on content filtering are met; moreover, the existing interface for content transmission is not required to be changed, so that the scheme compatibility and feasibility in the embodiment of the invention are high.
Example five:
the content filtering method provided in the embodiment of the present invention is further described below by using another specific example.
As shown in fig. 8, the method for filtering content in the embodiment of the present invention specifically includes the following steps:
801. the content filtering requester sends the group content and the group ID to a class-based content filtering Server (CBCS Server), requesting the content filtering Server to perform content filtering on the group content.
802. After the content filtering server identifies that a currently received filtering request aiming at the group content is a group ID, the content filtering server primarily filters the received group content according to a general filtering rule and/or a group filtering rule to obtain a primary filtering result, and determines the content category of the group content subjected to primary filtering according to the group content and/or relevant information in the corresponding filtering request by using a classification method and technology.
If the content filtering server is not a classification-based content filtering server or the content filtering rules do not include classification-based filtering rules, the content category may not need to be determined, and the following corresponding operation of sending the content category may be omitted.
In this step 802, the primary filtering may also perform corresponding operations according to the general filtering rules and/or the group filtering rules, such as: if the generic filtering rules and/or the group filtering rules relate to category-based filtering rules, the category needs to be determined first; the determination of the category may be an external acquisition, a local match or a classification with some algorithm, etc. The following steps are repeated: if the generic filtering rules and/or the group filtering rules relate to some external information, such as: age, sex, etc., it is first obtained from the outside.
803. If all or part of the group content passes the filtering in step 802, the content filtering server obtains the content filtering rules of each user in the group corresponding to the group ID according to the group ID, and generates a secondary filtering strategy for each user; the secondary filtering strategy obtained at this time includes: the content filtering rules of each user.
If all the group contents in step 802 are blocked and not sent to the user, step 803 is skipped and the process is terminated after step 804; or, only returning the primary filtering result to the content filtering requester, not returning the content category, and terminating the flow.
804. And the content filtering server returns a primary filtering result obtained after the group content is primarily filtered and the content category to which the group content after primary filtering belongs to a content filtering requester.
In the message fed back from the content filtering server to the content filtering requester, the content category may be represented following the following Schema (framework):
content-category-vector＝*(content-category[*region-code])
content-category＝[categorization-scheme-identifier]content-category-value
content-category-value＝*CHAR
the content presentation category vector is composed of a plurality of categories and their corresponding selectable region descriptions, and the categories are composed of selectable category standard identifiers and category values.
805. And the content filtering requester sends the primarily filtered group content and the content category to which the primarily filtered group content belongs to the user terminal.
The content filtering requester may issue the primary filtering result and the content category through a broadcast or multicast channel, or may send the primary filtering result and the content category through other manners.
806. And the content filtering server sends the secondary filtering strategy to the user terminal.
In this step, the secondary filtering policy may be actively issued by the content filtering server when the content filtering client on the user terminal registers with the content filtering server, or may be issued after the content filtering client initiates an acquisition request, or may be issued after the content filtering client determines that the secondary filtering policy has not been sent before when the content filtering server performs a primary filtering operation on the group content, thereby triggering a sending action; after receiving the secondary filtering policy, the user terminal stores the secondary filtering policy locally, so that the step 806 can be omitted in the subsequent implementation process of content filtering; then, when the secondary filtering policy changes, the content filtering server may actively send the updated secondary filtering policy to the user terminal.
807. And the user terminal performs content filtering on the primarily filtered group content according to the acquired secondary filtering strategy and the content category to which the group content belongs.
The secondary filtering policy may be a received secondary filtering policy sent by the content filtering server, or may be a secondary filtering policy that is directly read from a local store.
In the description of the above method, the number of each step is not used to limit the execution order thereof; for example, before performing the preliminary filtering, the content filtering server may obtain the content filtering rules of each user in the group corresponding to the group ID according to the group ID, generate a secondary filtering policy for each user, and send the secondary filtering policy to the user terminal.
In the embodiment of the invention, a content filtering server performs primary filtering on group content, a secondary filtering strategy for each user in a group is formulated through the content filtering server, the secondary filtering strategy comprises a content filtering rule of each user in the group, then the secondary filtering strategy is issued to a corresponding user terminal, and after the user terminal receives the primarily filtered group content provided by a content filtering requester and the content category to which the primarily filtered group content belongs, the user terminal completes secondary content filtering for a specific user according to the secondary filtering strategy;
by the scheme provided by the embodiment of the invention, the group content can be filtered according to the requirement of each user, and the accurate requirements of different users on content filtering are met; and under the condition that the secondary filtering strategy does not need to be updated, the content filtering server only needs to send the secondary filtering strategy to the user terminal once, so that the flow of information issued by the content filtering server can be reduced, the process is fast to execute, and meanwhile, the possibility of delay and error is low.
Example six:
in order to better implement the content filtering method in the fourth embodiment, the embodiment of the present invention further provides a content filtering server. Specifically, the content filtering server, as shown in fig. 9, includes: a receiving unit 91, a filtering unit 92, a determining unit 93, a first transmitting unit 94 and a second transmitting unit 95; wherein,
the content filtering server in the embodiment of the present invention receives the group content and the group identifier provided by the content filtering requester through the receiving unit 91, and the filtering unit 92 performs primary filtering on the group content received by the receiving unit 91 according to the general filtering rule and/or the group filtering rule corresponding to the group;
