Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
In social class application, customer relationship chain be by two two users between the chain that forms of specified relationship, this specified relationship includes but not limited to friend relation between two users, user pays close attention to the relation of another user, a user has relation of consulting the message that another user issues etc.
Each user can propagate sharing contents based on customer relationship chain.Such as, the sharing contents of oneself is distributed in the Twitter message of self by a user, is checked or obtain this sharing contents by other user with concern relation.Again such as, sharing contents is distributed in social information display platform by a user, checks by having friend relation and having other user obtaining authority or obtains this sharing contents.
But in view of many reasons such as politics, business, individual privacies, a part of sharing contents is inhibited in the application of social class and propagates, such as: relate to the speech of political sensitivity topic, relate to pornographic picture and text, the photo relating to star's privacy etc.In embodiments of the present invention, will forbid that according to shielding rules the sharing contents propagated in social class application is referred to as target sharing contents.The attendant that this shielding rules can be applied by social class formulates, and also can have User Defined.This shielding rules dynamically can also generate the report of same sharing contents based on multiple user.
When target sharing contents is propagated in social class application, propagate based on customer relationship chain.As shown in Figure 1, user 1 and user 2, user 3, user 4 have friend relation, and user 2 and user 5, user 6, user 7 have friend relation, and user 3 and user 8 have friend relation, user 4 and user 9 to 22 have friend relation, and user 9 and user 23 have friend relation.If each user forwards this target sharing contents, then, after user 1 shares a target sharing contents, the propagation chain of this target sharing contents is as follows:
User 1 → user 2 → user 5;
User 1 → user 2 → user 6;
User 1 → user 2 → user 7;
User 1 → user 3 → user 8;
User 1 → user 4 → user 9 → user 23;
User 1 → user 4 → user 10;
、、、
User 1 → user 4 → user 21;
User 1 → user 4 → user 22.
Analyze this propagation chain known, the propagation of target sharing contents has following features:
The first, target sharing contents always, after the user that good friend user is many forwards, obtains large-area diffusion, after such as target sharing contents is shared by user 4, has 14 people to have received this target sharing contents.
The second, except the original user of target sharing contents, other user forwards find target sharing contents in the sharing contents of good friend user after.
Also namely, if want the propagation of limited target sharing contents, on the one hand, shield at the original user place of target sharing contents, such as user 1 place as far as possible; On the other hand, as far as possible at the user place that good friend user is many, the forwarding of this target sharing contents to be limited, such as user 4 place.
In the embodiment of the present invention, the use that the original user of target sharing contents and the range of scatter after forwarding this target sharing contents exceed certain threshold value is thought propagating source user per family.
Please refer to Fig. 2, it illustrates the flow chart of the sharing contents screen method that one embodiment of the invention provides.The present embodiment is applied in the server of communication platform with this sharing contents screen method and illustrates, the method comprises:
Step 202, obtains at least one the target sharing contents shielded, and target sharing contents is the sharing contents forbidding propagation in social class application according to shielding rules.
Step 204, according to the propagation chain of at least one target sharing contents, analyzes and obtains propagating source user; Propagation chain when to be target sharing contents propagate based on relation chain in social class application user's chain of being formed of each user of process.
Step 206, user is to the propagation of other target sharing contents for shielding propagating source.
In sum, the sharing contents screen method that the present embodiment provides, by the propagation chain of multiple target sharing contents shielded, analyze the propagating source user obtaining producing target sharing contents, follow-up other target sharing contents shared of propagating source user is shielded; Solving prior art can only at target sharing contents by the certain number of times of propagation or after the time, the problem that could shield this target sharing contents; Reach the target sharing contents that propagating source user is shared, just can shield before sharing, avoid target sharing contents in relation chain, carry out the effect propagated as far as possible.
Please refer to Fig. 3, it illustrates the flow chart of the sharing contents screen method that another embodiment of the present invention provides.The present embodiment is applied in the server of communication platform with this sharing contents screen method and illustrates, the method comprises:
Step 301, obtains at least one the target sharing contents shielded, and target sharing contents is the sharing contents forbidding propagation in social class application according to shielding rules;
Server obtains at least one the target sharing contents shielded.Target sharing contents is more, and the propagating source user determined is more accurate.Each target sharing contents can be different.
The form of target sharing contents can be at least one in text, image, voice, video, webpage and application program.
Step 302, obtains the propagation chain of each target sharing contents, obtains at least one propagation chain;
Server also obtains the propagation chain of each target sharing contents, more than one of the propagation chain of each target sharing contents.Such as, target sharing contents illustrated in fig. 1 has 18 propagation chain.
Step 303, adds up the occurrence number of each user in propagation chain;
Server also adds up the occurrence number of each user in each propagation chain of each target sharing contents.
Such as, each user illustrated in fig. 1 in the occurrence number of the propagation chain of target sharing contents as following table one:
| User 1 | User 2 | User 3 | User 4 | User 5 | User 6 | User 7 | User 8 | User 9 | User 10 | User 11 | User 12 |
| 18 | 3 | 1 | 14 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
| User 13 | User 14 | User 15 | User 16 | User 17 | User 18 | User 19 | User 20 | User 21 | User 22 | User 23 | |
| 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
Table one
Certainly, usually have a lot of bar at the target sharing contents shielded, and each target sharing contents there is a lot of bar propagation chain usually.Above-mentioned table one is only and schematically illustrates.
Step 304, user occurrence number being exceeded first threshold is defined as propagating source user; Or, occurrence number sequence is defined as propagating source user the user of front n position;
The user that occurrence number can be exceeded first threshold by server is defined as propagating source user, and such as first threshold is 10 times, then user 1 and user 4 are defined as propagating source user.Wherein, user 1 is the original user of target sharing contents, and user 4 is the range of scatter users more than 10 after forwarding this target sharing contents.
Or server can sort to each user according to occurrence number, sequence is defined as propagating source user the user of front n position.Such as, when target sharing contents is a lot of, the user sorted at first 100 can be defined as propagating source user by server.
Alternatively, the size of first threshold and the number correlation of target sharing contents, or, the size of first threshold and the number correlation of propagation chain.
Same, the size of n and the number correlation of target sharing contents, or, the size of n and the number correlation of propagation chain.
Server directly can shield all sharing contents that propagating source user shares.Or propagating source user can be listed in anti-target monitoring list by server, and the sharing contents that the user being positioned at this anti-target monitoring list shares needs server to carry out anti-target monitoring.Here " sharing " comprising: deliver original sharing contents, or, forward the sharing contents of other user.
The operation that propagating source user lists in after anti-target monitoring list by server is as follows.
Step 305, what receive propagating source user transmission shares request, shares request and carries the sharing contents needing to be shared;
Server receive each user send share request; Server detects each user and whether belongs to anti-target monitoring list; If belong to anti-target monitoring list, then server determines to receive that propagating source user sends shares request.
This is shared request and carries the sharing contents needing to be shared.The form of sharing contents includes but not limited at least one in text, image, voice, video, webpage and application program.
Step 306, detects sharing contents and whether belongs to target sharing contents;
Server by the manual examination and verification of attendant or preset algorithm, can detect sharing contents and whether belongs to target sharing contents.
This preset algorithm can be the key content recognizer based on corpus, such as, and text recognition algorithms, image recognition algorithm, audio frequency and video recognizer etc.This corpus is set up based on the target sharing contents shielded.Because this corpus constantly can expand based on follow-up newfound target sharing contents, so preset algorithm carries out according to the target sharing contents that shielded the learning-oriented algorithm continued to optimize.
Newfound target sharing contents can be reported by user or the manual examination and verification of attendant obtain.
Such as, propagating source user asks the sharing contents shared to be " May 1, various jewellery can be wiped away tears clearance sale, the whole audience 1 folding ".By preset algorithm, server detects that this sharing contents comprises target keywords " clearance sale of wiping away tears ", " 1 folding ", then server detects that sharing contents belongs to target sharing contents.
Which kind of detection mode is the embodiment of the present invention adopt be not specifically limited to server.
Step 307, if sharing contents belongs to target sharing contents, then shields this sharing contents.
If the testing result of server is sharing contents belong to target sharing contents, then shield sharing contents.
The mode of shielding sharing contents, includes but not limited to:
Forbid sharing this sharing contents;
Or only propagating source user is visible for this sharing contents;
Or, delete this sharing contents.
In sum, the sharing contents screen method that the present embodiment provides, by the propagation chain of multiple target sharing contents shielded, analyze the propagating source user being produced or spread target sharing contents, follow-up other target sharing contents shared of propagating source user is shielded; Solving prior art can only at target sharing contents by the certain number of times of propagation or after the time, the problem that could shield this target sharing contents; Reach the target sharing contents that propagating source user is shared, just can shield before sharing, avoid target sharing contents in relation chain, carry out the effect propagated as far as possible.
The sharing contents screen method that the present embodiment provides, also by the occurrence number of each user of statistics on the propagation chain of target sharing contents, analysis obtains propagating source user, namely the original user of propagating source user can be found out, the user that diffusion target sharing contents is more serious can be found out again, the shielding of target sharing contents can be carried out on each more crucial node of propagation chain, reach with less manpower or computational resource, realize shield effectiveness as well as possible.
As a kind of possible implementation, the step 304 in Fig. 3 replaced realization can become step 304a to step 304c, as shown in Figure 4.
Step 304a, adds up the propagation effect power of each user;
The relation chain had due to each user is not identical, and the propagation effect power that each user has in social class application is also different.
Such as, a user is star, has more than one hundred million follower in microblog, then this user to share the propagation effect force rate of a microblogging larger.
Again such as, a user only has 5 good friends, even if this user shares a target sharing contents, whole 5 good friends forward, and range of scatter is still limited, so the propagation effect power of this user is lower.
Alternatively, server adds up the propagation effect power of each user according to the attribute information of each user, and attribute information comprises: at least one information in user gradation, user type, good friend's quantity and concern number.
User gradation and the definition of user type in different social class application can be different.Such as, in microblog, user type can be divided into " large V " user by real-name authentication and domestic consumer; Again such as, in micro-letter platform, user type can be divided into public number and common account number.
Every attribute information can corresponding respective weight and quantized value, and server calculates propagation effect power according to the weight of every attribute information and quantized value.
Schematically, the user gradation of a user is 10 grades, and user type is " large V " user, and good friend's quantity is 200 people, and concern number is 50000 people, then server calculates the propagation effect power of this user and is:
10* weight 1+1* weight 2+200* weight 3+50000* weight 4.
Wherein, 1 is the quantized value of " large V " user, and weight 1 is the weight that user gradation is corresponding, and weight 2 is weights corresponding to user type, and weight 3 is weights corresponding to good friend's quantity, and weight 4 is weights corresponding to concern number.
Step 304b, according to occurrence number and propagation effect power, calculates the hazard index that each user shares target sharing contents;
Server directly can also calculate the product of occurrence number and propagation effect power, shares the hazard index of target sharing contents as each user.
Alternatively, occurrence number also correspondence has weight a, and propagation effect power also correspondence has weight b, and server calculates the hazard index that each user shares target sharing contents and is:
Occurrence number * weight a+ propagation effect power * weight b.
Step 304c, user hazard index being exceeded Second Threshold is defined as propagating source user.
In sum, the sharing contents screen method that the present embodiment provides, also by analyzing propagating source user in conjunction with occurrence number and propagation effect power, can analyze propagating source user more accurately.No matter be original user, or the user that diffusion target sharing contents is more serious, can under the amplification of respective weights, rapid serviced device identified, thus improves the accuracy of follow-up shielding process.
As the implementation that another kind is possible, because the testing result in step 306 may make a mistake.Step 308 is also comprised to step 311, as shown in Figure 5 after step 306 in Fig. 3.
Step 308, if sharing contents does not belong to target sharing contents, then allows sharing of sharing contents;
If server testing result is not within step 306 for belong to target sharing contents, then server allows sharing of this sharing contents.
Step 309, that records this sharing contents shares number of times;
Server is after allowing to share this sharing contents, and that also records this sharing contents shares number of times.
Step 310, detection is shared number of times and whether is reached the 3rd threshold value;
Step 311, if share number of times more than the 3rd threshold value, then again detects sharing contents and whether belongs to target sharing contents.
Also namely, if this sharing contents share number of times more than the 3rd threshold value, then it is more popular for representing this sharing contents, or potentially become more popular sharing contents, now server again detects sharing contents and whether belongs to target sharing contents.
If so, then step 307 is entered; If not, then enter step 308, but no longer perform step 309 afterwards.
Alternatively, in testing process again, detection mode is different from the detection mode of testing process last time.Such as, use preset algorithm to detect in step 306, in step 311, adopt the manual detection of attendant.
Alternatively, in testing process again, server still adopts preset algorithm to detect sharing contents whether to belong to target sharing contents.But because preset algorithm carries out according to the target sharing contents that shielded the learning-oriented algorithm continued to optimize, if there is new corpus to add in twice testing process, then testing process still likely eliminates the detection mistake of testing process last time again.
In sum, the sharing contents screen method that the present embodiment provides, by changing detection method or using learning-oriented preset algorithm again to check, makes target sharing contents on a large scale before propagating, through twice testing process, reduce the diffusion possibility of target sharing contents.And in prior art, owing to being judge for every bar sharing contents, if carry out twice testing process, a large amount of computational resources can be consumed.In the sharing contents that the present embodiment is only shared propagating source user, the sharing contents that there is suspicion carries out twice testing process, under the prerequisite using less computational resource, realizes the shielding of target sharing contents more accurately.
