Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments.

s2, mapping the target mobile phone number into a designated vector in a high-dimensional virtual space by using the feature information according to a preset high-dimensional vector mapping algorithm, wherein a plurality of standard high-dimensional vectors are preset in the high-dimensional virtual space and are respectively associated with a plurality of preset information sending strategies;

s4, calculating a plurality of first distances according to a preset distance calculation method, wherein the first distances are distances between the designated vectors and the temporary vectors;
s5, judging whether the first distances are all smaller than a preset distance threshold value;
and S6, if the plurality of first distance unevenness is smaller than a preset distance threshold, acquiring an appointed information sending strategy corresponding to the first distance with the largest value according to the corresponding relation of the first distance, the temporary vector and the information sending strategy, and sending information to the target mobile phone number according to the appointed information sending strategy.
As described in step S1, a target mobile phone number is obtained, and feature information of a user of the target mobile phone number is obtained, where the feature information at least includes identity information of the user, a duration of using APP by the user, and a ratio of APP push messages clicked by the user to all received APP push messages. The characteristic information is used for subsequently judging whether information is sent to the target mobile phone number in the form of APP push message or short message sending. The feature information includes identity information, wherein the identity information includes occupation, age, education background, work background, etc. for example, since the possibility of whether to click APP push information is different for users with different identities under the same other conditions, it is possible to determine which information sending strategy the user is adapted to, by using the feature information including the identity information of the user, the duration of using APP by the user, and the proportion of all APP push messages received by the APP push message clicked by the user.
As described in step S2, according to a preset high-dimensional vector mapping algorithm, the target mobile phone number is mapped to a designated vector in a high-dimensional virtual space by using the feature information, where a plurality of standard high-dimensional vectors are preset in the high-dimensional virtual space, and the plurality of standard high-dimensional vectors are respectively associated with a plurality of preset information sending strategies. The preset high-dimensional vector mapping algorithm maps the target mobile phone number to a specified vector in a high-dimensional virtual space by using the feature information, and the specific vector is, for example: and assigning different pieces of sub information in the feature information, and respectively using a plurality of numerical values obtained by assigning as numerical values of each sub vector of the designated vector, thereby realizing mapping in a high-dimensional virtual space. The high-dimensional virtual space is preset with a plurality of standard high-dimensional vectors, and the plurality of standard high-dimensional vectors are respectively associated with a plurality of preset information sending strategies. Therefore, only the standard high-dimensional vector closest to the target mobile phone number needs to be obtained, and then the corresponding information sending strategy is adopted to complete information sending.
As described in step S3, a plurality of temporary vectors are screened from the plurality of standard high-dimensional vectors according to a predetermined vector screening method. The preset vector screening method includes: according to the formula:
calculating the length Lc of a specified vector, wherein C is the specified vector, Ci is the ith partial vector of the specified vector C, and the specified vector C has m partial vectors; according to the formula:
calculating the length Lp of the standard high-dimensional vector, wherein P is the P-th standard high-dimensional vector, Pi is the ith component vector of the P-th standard high-dimensional vector, and the P-th standard high-dimensional vector has m component vectors; according to the formula: and respectively calculating a plurality of length differences between the designated vector and the plurality of standard high-dimensional vectors, and selecting a plurality of temporary vectors from the plurality of length differences according to a selection rule that the length differences are smaller than a preset difference threshold value. Thereby selecting a temporary vector that is closer to the given vector.
As described in step S4, a plurality of first distances are calculated according to a preset distance calculation method, where the first distances are distances between the designated vector and the temporary vector. The manner of obtaining the plurality of first distances by calculation according to a preset distance calculation method is, for example: according to the formula:
and calculating a plurality of first distances DIS, wherein the first distances DIS are distances between the designated vector and the temporary vector, C is the designated vector, Ci is the ith component vector of the designated vector C, the designated vector C has m components, D is the temporary vector, Di is the ith component vector of the temporary vector D, and the temporary vector D has m components. Wherein the maximum value of the first distance is 1, and the closer the value of the first distance is to 1, the more similar the corresponding temporary vector is to the designated vector.
As described in step S5, it is determined whether each of the first distances is smaller than a preset distance threshold. The first distance reflects the similarity between a designated vector and a temporary vector, but if the values of the first distances are not large, the similarity between the corresponding temporary vector and the designated vector is low even if the largest distance among the first distances is found. Therefore, the method adopts a preset distance threshold value mode to eliminate misjudgment caused by the condition that the numerical values of the plurality of first distances are not large.
As described in step S6, if the plurality of first distance unevenness is smaller than the preset distance threshold, the specific information sending policy corresponding to the first distance with the largest value is obtained according to the correspondence between the first distance-temporary vector-information sending policy, and information is sent to the target mobile phone number according to the specific information sending policy. The first distance is related to a temporary vector (i.e. a standard high-dimensional vector) and the standard high-dimensional vector is related to an information sending strategy, so that a corresponding specified information sending strategy can be obtained according to the first distance with the largest value. Since the standard high-dimensional vector corresponding to the first distance with the largest value is most similar to the designated vector, it indicates that the designated information transmission policy is most suitable for the user. And sending information to the target mobile phone number according to the specified information sending strategy. The specific information sending policy is, for example: whether an APP message pushing mode is adopted or not; whether a short message sending mode is adopted or not; when to send the information, etc.

s201, dividing the characteristic information into identity information and other information except the identity information;
s202, according to the corresponding relation between preset information and vectors, respectively mapping the identity information and the other information into a first vector component group A and a second vector component group B;
s203, acquiring an influence parameter group k1-kn of the first vector group A to the second vector group B according to a preset influence relation of the first vector group to the second vector group;
s204, according to a formula: and calculating to obtain a designated vector C (A, k1B1, k2B2, … and knbn), wherein the second component vector group B is (B1, B2, … and bn), and n is an integer greater than 0.
As described above, the target mobile phone number is mapped to the designated vector in the high-dimensional virtual space by using the feature information according to the preset high-dimensional vector mapping algorithm. This application will characteristic information divide into identity information and except other information outside the identity information, wherein because crowd's specificity, the crowd of consequently different identities is different to APP propelling movement information's processing mode, for example A identity crowd is more enthusiastic to click APP propelling movement information, and B identity crowd dislikes APP propelling movement information etc. therefore identity information can be to except other information outside the identity information have potential influence. Accordingly, the influence parameter group k1-kn of the first vector group A to the second vector group B is obtained according to the influence relation of a preset first vector group to the second vector group; according to the formula: and calculating to obtain a designated vector C, wherein the second vector group B is composed of n component vectors B1, B2, … and bn, so that the designated vector is generated more accurately. The influence parameter group k1-kn can be generated in advance by any means, for example, by analyzing the identity information versus other information except the identity information, and can be analyzed by adopting a supervised learning manner based on a machine learning model to obtain the influence parameter group.
In one embodiment, the step S3 of screening a plurality of temporary vectors from a plurality of standard high-dimensional vectors according to a predetermined vector screening method includes:
s301, according to a formula:
s302, according to a formula:
s303, according to a formula: and respectively calculating a plurality of length differences between the designated vector and the plurality of standard high-dimensional vectors, and selecting a plurality of temporary vectors from the plurality of length differences according to a selection rule that the length differences are smaller than a preset difference threshold value.
As described above, it is realized to screen a plurality of temporary vectors from a plurality of standard high-dimensional vectors according to a preset vector screening method. Wherein the length Lc of a given vector refers to the distance between the end point and the start point of said given vector in the high-dimensional virtual space. If there is a standard high-dimensional vector similar to the given vector, the length of this standard high-dimensional vector must be the same as or similar to the length of the given vector, according to the formula: and respectively calculating a plurality of length differences between the designated vector and the plurality of standard high-dimensional vectors, and selecting a plurality of temporary vectors from the plurality of length differences according to a selection rule that the length differences are smaller than a preset difference threshold value. Therefore, the temporary vectors are preliminarily screened out to reduce the total calculation load.
In one embodiment, the step S4 of calculating a plurality of first distances according to a preset distance calculation method, where the first distances are distances between the designated vector and the temporary vector, includes:
s401, according to a formula:
As described above, it is realized that the plurality of first distances are calculated according to a preset distance calculation method. The first distance DIS reflects the degree of similarity between the given vector and the temporary vector. This application adopts according to the formula:
the way of calculating the first distance can accurately know the distance between the designated vector and the temporary vectorTo a similar degree. Further, before calculating the plurality of first distances according to a preset distance calculation method, the method further comprises the following steps:
calculating the length Lc of a specified vector, wherein C is the specified vector; according to the formula:
calculating the length Lp of the standard high-dimensional vector; according to the formula: and respectively calculating a plurality of length differences between the designated vector and the plurality of standard high-dimensional vectors, and selecting a plurality of temporary vectors from the plurality of length differences according to a selection rule that the length differences are smaller than a preset difference threshold value so as to preliminarily screen the plurality of temporary vectors. Wherein, the formula is adopted:
the first distance is calculated by considering the angle difference between vectors and neglecting the value difference between vectors, and when a plurality of temporary vectors are preliminarily screened, the value difference between vectors is actually screened, and the obtained temporary vectors are close to the value of the designated vector. In conclusion, the plurality of first distances are calculated more accurately.
In one embodiment, the step S4 of calculating a plurality of first distances according to a preset distance calculation method, where the first distances are distances between the designated vector and the temporary vectors, includes:
s411, performing copy replacement operation on the placeholder vector to obtain the placeholder vector after the replacement operation is performed, wherein the copy replacement operation is used for replacing a copy placeholder in the placeholder vector with a component vector value with the same dimensionality in the designated vector;
s412, according to the formula:
As described above, it is realized that the plurality of first distances are calculated according to a preset distance calculation method. Wherein the plurality of temporary vectors comprise a placeholder vector and a non-placeholder vector, a part of the placeholder vectors are occupied by a copying placeholder, and the copying placeholder is used for copying and replacing the value of the component vector with the same dimension in the designated vector. The standard high-dimensional vector can thus be set as a special occupancy vector to adapt to situations where part of the features are not considered. For example, for a family vector (i.e., a vector corresponding to a user with frequent family member interactions), the influence of irrelevant features, such as consumption habits and other features (which do not or do not have much influence on whether the family member interactions are frequent) can be eliminated or reduced by using the copy placeholder, and the influence can be eliminated or reduced by using the copy placeholder in the family vector. And then, a plurality of first distances DIS are obtained through calculation, so that the accuracy of the first distance calculation is improved.
In one embodiment, the step S6, where the occupancy vector is a home vector, a numerical value of a first distance corresponding to the home vector is the largest among the plurality of first distances, and the designated information sending policy corresponding to the first distance with the largest numerical value is obtained according to a correspondence between the first distance-temporary vector-information sending policy, and information is sent to the target mobile phone number according to the designated information sending policy includes:
s601, acquiring a designated information sending strategy corresponding to the family vector, wherein the designated information sending strategy is to send a complete short message or push a complete APP message to only one of family members of the target mobile phone number user;
s602, judging whether any member in the family of the target mobile phone number user receives a complete short message or a pushed complete APP message;
s603, if any member in the family of the target mobile phone number user receives the short message or the pushed APP message, sending a short message or a pushed short APP message to the target mobile phone number, wherein the short message is one part of the complete short message, and the short APP message is one part of the complete APP message.
As described above, according to the correspondence relationship between the first distance-temporary vector-information transmission policy, the designated information transmission policy corresponding to the first distance having the largest numerical value is obtained, and information is transmitted to the target mobile phone number according to the designated information transmission policy. The family vector refers to a vector corresponding to a user with frequent family member interaction, and generally, information transmission for the whole family can be realized only by sending one piece of complete information because the family member interacts frequently, and the information is probably forwarded to a member B because the member A receives the information, or the information is received by the member A, whether all family members need the information or not is considered, so that the information transmission for the whole family is realized, and therefore, the corresponding specified information transmission strategy is to only send a complete short message to one of the family members of the target mobile phone number user or push a complete APP message. And because the family vector is a special type of standard high-dimensional vector, the family vector is set as a placeholder vector, so that the influence of irrelevant features is eliminated by copying the placeholder. And in order to further guarantee the communication of information, this application adopts if any member in target cell-phone number user's the family has received SMS or the APP message of propelling movement, then to target cell-phone number sends brief SMS or the short APP message of propelling movement, wherein brief SMS is partly in the complete SMS, brief APP message is partly in the complete APP message the mode to the short information has realized reminding once more of information. The simplified information is only a part of the original information, so that the consumed communication resources and the cost are less, but the quality of information transmission is not reduced due to the high interaction frequency of family members.
In one embodiment, after the step S5 of determining whether each of the first distances is smaller than a preset distance threshold, the method includes:
s51, if the first distances are all smaller than a preset distance threshold, obtaining historical data of click APP push messages of the terminal corresponding to the user, and dividing the terminal into designated levels according to the historical data;
s52, judging whether the designated level is greater than a preset level threshold value;
s53, if the specified level is larger than a preset level threshold, judging whether the terminal unloads the APP;
s54, if the terminal does not unload the APP, judging whether the terminal keeps long heartbeat connection with a server side corresponding to the APP;
and S55, if the terminal keeps long heartbeat connection with the server side corresponding to the APP, sending information to the target mobile phone number in an APP message pushing mode.
As described above, if the plurality of first distances are all smaller than the preset distance threshold, the cost is reduced on the premise of ensuring the information arrival rate by adopting a multi-process judgment mode. If the plurality of first distances are smaller than the preset distance threshold, it is indicated that the user cannot correspond to the existing information sending strategy, and therefore the information sending strategy needs to be formulated in real time. The historical data of clicking the APP push message is, for example, the total times, total days, the duration of clicking and reading the APP push message, and the like of clicking the APP push message, and the terminal is divided into the specified levels according to the historical data, wherein the higher the level is, the higher the possibility that the terminal clicks the APP push message is. Judging whether the designated level is greater than a preset level threshold value; if the specified level is greater than a preset level threshold, judging whether the terminal unloads the APP; if the terminal does not unload the APP, judging whether the terminal keeps long heartbeat connection with a server side corresponding to the APP; if the terminal keeps long heartbeat connection with the server side corresponding to the APP, information is sent to the target mobile phone number in an APP push message mode, and therefore cost is reduced on the premise that information arrival rate is guaranteed. Further, if the specified level is not greater than a preset level threshold, or if the terminal unloads the APP, or if the terminal does not keep a long heartbeat connection with a service end corresponding to the APP, sending information in a short message manner.
The information sending method based on the distance obtains a target mobile phone number and obtains the characteristic information of a user of the target mobile phone number; mapping the target mobile phone number into a designated vector in a high-dimensional virtual space by using the characteristic information; screening a plurality of temporary vectors from a plurality of standard high-dimensional vectors; calculating a plurality of first distances, wherein the first distances are distances between the designated vector and the temporary vector; judging whether the first distances are all smaller than a preset distance threshold value; if the plurality of first distance unevenness is smaller than a preset distance threshold, acquiring an appointed information sending strategy corresponding to the first distance with the largest value according to the corresponding relation of the first distance, the temporary vector and the information sending strategy, and sending information to the target mobile phone number according to the appointed information sending strategy. Therefore, the information is transmitted in a targeted manner, and the information transmission cost is reduced on the premise of ensuring the delivery rate.
