The content of embodiment corresponding to composition graphs 1, Fig. 2 is the process flow diagram of a kind of information intercepting method provided according to an exemplary embodiment.Wherein, this information intercepting method can be applied to any common platform.The executive agent of this information intercepting method can be the one or more server of common platform.See Fig. 2, the method flow that the embodiment of the present invention provides comprises:
201, the information to be delivered on common platform is obtained.
Common platform is can be used for user to carry out mutual any internet platform, and user can deliver information on common platform, and the information also can delivered other users is commented on, forward, collect, put and praise.The type of common platform can have a variety of, and such as, common platform is microblogging, blog, community, mhkc, forum etc.
Preferably, may built-in interaction platform in game application, for contents such as interactive game skill, tactics of the game between user.Carry out interaction because every day on the interaction platform in game application all has many consumers, therefore, a lot of UGC can be produced.Malicious user is in order to promote its product or service; advertisement or the irrelevant junk information of other and game are delivered in frequent meeting on interaction platform, and in order to contain this behavior of malicious user, the common platform in the embodiment of the present invention can preferably be played the interaction platform in application; as, game community etc.About the type of game application, the embodiment of the present invention does not do concrete restriction.This game application can be preferably mobile phone games, and certainly, game application also can be computer game etc.
Wherein, obtain on common platform in time delivering information, the information that the terminal that can use by receiving user is submitted to realizes.Particularly, user delivers in time delivering information on common platform, can realize in the appointed area of terminal.Wherein, this appointed area can be in the client that common platform is corresponding, for providing the region of information input function.User can input information to be delivered in this appointed area, and is committed to common platform or its server by submitting option to or delivering option.
About the type of information to be delivered, can have a variety of.Such as, can be the combination etc. of a kind of in text, picture, voice and video or at least two kinds, the embodiment of the present invention do concrete restriction to this.In conjunction with the type of common platform, when common platform is the interaction platform in game application, information to be delivered may be the combination etc. with a kind of in game points, game picture, game sectional drawing, game item, game video or at least two kinds.
What 202, obtain information to be delivered delivers user, and judges whether deliver user is present in default blacklist, when determining that delivering user is present in default blacklist, performs step 205; When determining that delivering user is not present in default blacklist, perform step 203.
This step is optional step.Delivering user is the user delivering this information to be delivered.Preset in blacklist to have prestored and deliver the many users of junk information number of times, the user preset in blacklist will be prohibited to deliver information.
Wherein, obtain wait deliver information deliver user time, can be realized by the user profile obtaining information to be delivered, and determine to deliver user according to user profile further.About the type of user profile, can have a variety of.Such as, can for delivering account, the cell-phone number or mailbox etc. of user.
In addition, when judging whether deliver user is present in default blacklist, the user profile delivering each user in the user profile of user and default blacklist can be compared and realizing.When the user profile of user arbitrary in default blacklist is identical with the user profile delivering user, determine that delivering user is present in default blacklist; When the user profile of users all in default blacklist is all not identical with the user profile delivering user, determine that delivering user is not present in default blacklist.
203, the similarity between information to be delivered and the junk information marked is calculated.
Wherein, the junk information marked can be advertisement, also can be flame etc.In conjunction with the type of common platform, when common platform is the interaction platform in game application, the junk information marked can for the advertisement that be published on game application interaction platform marked, or other information had nothing to do with game content.Particularly, marked junk information by after keeper's mark of common platform, to be stored in property data base.Calculating in time delivering the similarity between information and the junk information marked, directly can obtain the junk information marked from property data base.About the quantity of the junk information marked, relevant with the quantity that cut-off current time has been defined as junk information.When the junk information marked has multiple, calculating in time delivering information and marked the similarity between junk information, the similarity between information to be delivered and each junk information marked need calculated.
In embodiments of the present invention, for arbitrary junk information marked, calculating in time delivering the similarity between information and this junk information marked, include but not limited to as follows 2031 and step 2032 realize:
2031, determine the First Eigenvalue of information to be delivered, and obtain the Second Eigenvalue of the junk information marked.
Wherein, determine that the process of the First Eigenvalue of information to be delivered is the process of the feature extracting information to be delivered.In embodiments of the present invention, the First Eigenvalue is the eigenwert of information to be delivered, and Second Eigenvalue is the eigenwert of the junk information marked.When the junk information marked is advertisement, Second Eigenvalue is the eigenwert of the advertisement marked.The concrete form of the First Eigenvalue can be relevant to the type of information to be delivered.Such as, when when the information of delivering is text, its First Eigenvalue can be text itself.When the information of delivering is picture, audio frequency, video or voice, the First Eigenvalue can be cryptographic hash or perception cryptographic hash etc.
Further, determining in time delivering the First Eigenvalue of information, can determine in conjunction with the type of information to be delivered.Such as, when when the information of delivering is text, its text size can directly be calculated, using the First Eigenvalue of text size as information to be delivered.When the information of delivering is picture, audio frequency, video or voice, the cryptographic hash of information to be delivered can be calculated, using the First Eigenvalue of this cryptographic hash as information to be delivered.
When obtaining the Second Eigenvalue of the junk information marked, the junk information marked can be obtained, and by the above-mentioned mode calculating the First Eigenvalue of information to be delivered, calculate the Second Eigenvalue of the junk information marked.In addition, property data base, when storing the junk information marked, also stored for the eigenwert of each junk information marked.Now, when obtaining the Second Eigenvalue of the junk information marked, the eigenwert of the junk information marked can directly be read from property data base.About the content of property data base, will explain in detail in subsequent content, wouldn't describe herein.
Alternatively, before the First Eigenvalue determining information to be delivered, the information of delivering can also be treated and carry out pre-service, such as, treat the information of delivering and do some judgements or filter.As, text is too short, only has one or two word, be then not suitable for calculating, and ignores this information to be delivered, and does not carry out the step of follow-up calculating similarity.And for example, if newline or space too much, then calculate feature after can removing these newlines or space again in the text in information to be delivered.By pre-service, calculated amount when calculating similarity can be reduced, thus can system resource be saved, and can counting yield be improved.
2032, according to the First Eigenvalue and Second Eigenvalue, the similarity between information to be delivered and the junk information marked is calculated.
Particularly, according to the First Eigenvalue and Second Eigenvalue, calculate in time delivering the similarity between information and the junk information marked, also can have different modes according to the type of information to be delivered.During concrete enforcement, include but not limited to following several situation:
The first situation: when information to be delivered and the junk information that marked are text, the First Eigenvalue is the text size of information to be delivered, when Second Eigenvalue is the text size of the junk information marked, according to the editing distance between information to be delivered and the junk information marked, the similarity between information to be delivered and the junk information marked can be calculated.
Particularly, the similarity can determining between information to be delivered and the junk information marked by following formula according to editing distance:
S = 1 - L m a x ( a , b ) - - - ( 1 )
In formula (1), S represents the similarity between information to be delivered and the junk information marked, L represents the editing distance between information to be delivered and the junk information marked, and a represents the text size of information to be delivered, and b represents the text size of the junk information marked.
Such as, when information to be delivered is " this is an advertisement ", the junk information marked is " this is a long advertisement ", then can calculate editing distance is 1, and the text size of information to be delivered is 6, and the text size of the junk information marked is 7, now, similarity is: 1-1/7=6/7.
The second situation: when information to be delivered and the junk information that marked are picture, the First Eigenvalue is the first cryptographic hash of information to be delivered, when Second Eigenvalue is the second cryptographic hash of the junk information marked, 2032.1 to step 2032.4 can calculate the similarity between information to be delivered and the junk information marked as follows:
2032.1, when the first cryptographic hash is equal with the second cryptographic hash, determine that information to be delivered is similar to the junk information marked.
2032.2, when the first cryptographic hash and the second cryptographic hash unequal time, calculate the first perception cryptographic hash of information to be delivered, and obtain the second perception cryptographic hash of junk information marked.
About the first perception cryptographic hash mode calculating information to be delivered, can see the account form of existing perception cryptographic hash, the embodiment of the present invention does not make specific explanations at this.
In addition, when obtaining the second perception cryptographic hash of the junk information marked, can be realized by the mode of the first perception cryptographic hash calculating information to be delivered.But, when property data base is when storing the junk information marked, also stored for cryptographic hash and the perception cryptographic hash of each junk information marked.Now, the second perception cryptographic hash of the junk information marked directly can be read from property data base.
2032.3, the Hamming distance between the first perception cryptographic hash and the second perception cryptographic hash is calculated.
Wherein, in information theory, the Hamming distance between two isometric character strings is the number of the kinds of characters of two character string correspondence positions.In other words, it is exactly that a character string is transformed into the character number replaced required for another one character string.Such as: the Hamming distance between 1011101 and 1001001 is 2.
In conjunction with this content, during Hamming distance between calculating first perception cryptographic hash and the second perception cryptographic hash, can by calculate be transformed into the second perception cryptographic hash by the first perception cryptographic hash time, the character number of required replacement realizes.
2032.4, the similarity between information to be delivered and the junk information marked is determined according to Hamming distance.
Particularly, the mode of the similarity between information to be delivered and the junk information marked is being determined according to Hamming distance, see in the first situation above-mentioned, the mode of the similarity between information to be delivered and the junk information marked can be determined according to editing distance, repeats no more herein.
The third situation: when when the information of delivering is the multimedia messages such as video, audio frequency, determine the mode of the similarity between information to be delivered and the junk information marked, can with above-mentioned when the mode when the information of delivering is picture consistent, repeat no more herein.
In addition, it should be noted that, when when the information of delivering is text, determine in time delivering the similarity between information and the junk information marked, except can adopting the mode described in the first situation above-mentioned, can also with above-mentioned when the mode when the information of delivering is picture consistent.
204, judging whether similarity is greater than the first predetermined threshold value, when determining that similarity is greater than the first predetermined threshold value, performing step 205; When determining that similarity is not more than the first predetermined threshold value, perform step 206.
In embodiments of the present invention, when similarity is greater than the first predetermined threshold value, then can determine that information to be delivered is similar with the junk information marked.When similarity is not more than the first predetermined threshold value, then the junk information dissmilarity can determined information to be delivered and mark.
About the concrete numerical value of the first predetermined threshold value, the embodiment of the present invention does not do concrete restriction.During concrete enforcement, can set as required.Such as, this first predetermined threshold value can be 0.7,0.8 etc.But in order to guarantee accurately to determine that whether information to be delivered is similar to the junk information marked, this first predetermined threshold value can arrange larger.
205, treat the information of delivering to tackle.
In embodiments of the present invention, when in time delivering the similarity between information and the junk information marked and be greater than the first predetermined threshold value, information to be delivered is tackled.Wherein, tackling in time delivering information, information to be delivered can deleted, thus do not delivering this information to be delivered, and delivering the reminder message of failure to the terminal return message delivering user.
Such as, when the junk information marked is advertisement, and in time delivering the similarity between information and the advertisement marked and be greater than the first predetermined threshold value, then can determine that information to be delivered may be advertisement.Now, by tackling this information to be delivered, the phenomenon arbitrarily distributing advertisement on common platform arbituarily can be avoided to occur, thus the normal order of common platform can be safeguarded.
Again such as, when the interaction platform that common platform is in game application, and the junk information marked be marked be published in game application in interaction platform on advertisement time, if the similarity between information to be delivered and the advertisement being published on the interaction platform in applying of playing marked is greater than the first predetermined threshold value, then can determine that information to be delivered may for being published in the advertisement on game application interaction platform.Now, by tackling this information to be delivered, the phenomenon interaction platform of malicious user in game application arbitrarily being distributed advertisement arbituarily can be avoided to occur, thus the normal order of interaction platform in game application can be safeguarded.
Further, when judging that similarity is greater than the first predetermined threshold value by step 204, tackling this after delivering information, directly this can also be delivered user and adding in default blacklist.But, in order to avoid bringing bad impact by delivering user to add default blacklist to user by mistake, the embodiment of the present invention can also be added up this and be delivered in the information that user delivers, and the similarity between the junk information marked is greater than the quantity of the first predetermined threshold value, when this quantity be greater than specify numerical value time, then this is delivered user and adds default blacklist.About specifying the concrete numerical value of numerical value, can set as required, such as, being set to 10,20 etc.
In addition, in embodiments of the present invention, when being determined that by step 202 delivering user is present in default blacklist, also information to be delivered can directly be tackled.By default blacklist, directly can tackle some information delivered by the user preset in blacklist, catching rubbish information simple to operate.
206, will information fusion be delivered in property data base, and will information be delivered stored in information database, wherein, property data base at least comprises the occurrence number of feature and each feature having delivered information, information database be used for store delivers information.
Wherein, as shown in Figure 3, it illustrates a kind of by information fusion to be delivered to the process flow diagram of property data base.As shown in Figure 3, this flow process comprises step 2061 to step 2064:
2061, the feature of information to be delivered is extracted.
Wherein, the principle extracting the feature of information to be delivered is identical with the principle of the First Eigenvalue determining information to be delivered in above-mentioned steps 2031, specifically see the content in above-mentioned steps 2031, can repeat no more herein.
2062, each feature in the feature of information to be delivered and property data base is compared, and according to whether there is the feature of information to be delivered in the feature of comparison result judging characteristic database, exist in the feature of property data base in time delivering the feature of information, perform step 2063; Do not exist in time delivering the feature of information in the feature of property data base, perform step 2064.
Wherein, before each feature in the feature of information to be delivered and property data base being compared, each feature in property data base can first be read.
Particularly, each feature in the feature of information to be delivered and property data base is being compared, and whether exist in time delivering the feature of information according in the feature of comparison result judging characteristic database, each feature in the feature of information to be delivered and property data base can be compared one by one, when the some features in property data base are with when the feature delivering information is identical, comparison result is the feature that there is information to be delivered in the feature of property data base; When all features in property data base are with when the feature delivering information is all not identical, comparison result is the feature that there is not information to be delivered in the feature of property data base.
Due to a lot of features may be comprised in property data base, if each feature in the feature of information to be delivered and property data base is all compared, can ensure accurately without determine whether to have existed in property data base information to be delivered feature with omitting.But, each feature in the feature of information to be delivered and property data base is all compared, has many calculated amount, thus can take many system resource.In conjunction with this partial content, when each feature in the feature delivering information and property data base being compared, some can also only selecting in property data base are enlivened feature to realize.
Wherein, enliven feature and refer to that the difference between the moment of recording feature and current time is less than the feature of the first appointment duration, e.g., the feature feature of writing time within 24 hours; Or for the difference between moment of recording feature and current time is less than the second appointment duration, and the feature of the large appointment numerical value of the occurrence number of feature, if feature writing time is within a week and the occurrence number feature that is greater than 20.
In conjunction with the above-mentioned content enlivening feature, each feature in the feature of information to be delivered and property data base is being compared, and whether exist in time delivering the feature of information according in the feature of comparison result judging characteristic database, can first select to enliven feature in property data base, thus the feature of enlivening in the feature of information to be delivered and property data base compared, and enliven according to comparison result determination property data base the feature that whether there is information to be delivered in feature.
When the some features of enlivening in property data base are with when the feature delivering information is identical, comparison result be property data base enliven in feature the feature that there is information to be delivered; When enlivening feature with when the feature delivering information is all not identical selected in property data base, comparison result be property data base enliven the feature that there is not information to be delivered in feature.
2063, by the occurrence number increase of the feature of information to be delivered in property data base once.
Such as, if the feature of the information to be delivered of current record is 15 in property data base, then the occurrence number of the feature of information to be delivered in property data base is updated to 16.
2064, information to be delivered is added in property data base.
When comparison result is do not exist in the feature of property data base in time delivering the feature of information, for the ease of the feature of the feature of this information to be delivered and the follow-up information to be delivered got being compared, this information to be delivered is added in property data base by the embodiment of the present invention.
About the form of property data base record data, the embodiment of the present invention does not do concrete restriction.During concrete enforcement, property data base can comprise a summary sheet and a details table.Wherein, summary sheet for recording cut-off current time, according to the feature of each Information Statistics analyzed and the association attributes of each feature.Details table is for recording the particular content of each information.
