The best implementation of this application

1, an embodiment of the present application provides a distance-based information sending method, including the following steps:

S1. Obtain the target mobile phone number and the characteristic information of the user who acquired the target mobile phone number. The characteristic information includes at least the identity information of the user, the length of time the user uses the APP, and the user clicks The proportion of APP push messages to all APP push messages received;

S2. According to a preset high-dimensional vector mapping algorithm, use the feature information to map the target mobile phone number to a designated vector in a high-dimensional virtual space, wherein a plurality of standard heights are preset in the high-dimensional virtual space. Dimensional vector, multiple standard high-dimensional vectors are respectively associated with multiple preset information sending strategies;

S3. Filter out multiple temporary vectors from multiple standard high-dimensional vectors according to a preset vector screening method;

S4. Calculate multiple first distances according to a preset distance calculation method, where the first distances are the distances between the designated vector and the temporary vector;

S5. Determine whether the plurality of first distances are all less than a preset distance threshold;

S6. If a plurality of the first distances are not uniformly smaller than a preset distance threshold, obtain the designated information sending strategy corresponding to the first distance with the largest value according to the correspondence relationship of the first distance-temporary vector-information sending strategy, and Sending information to the target mobile phone number according to the specified information sending strategy.

As described in step S1 above, the target mobile phone number is acquired, and the characteristic information of the user who acquires the target mobile phone number. The characteristic information includes at least the identity information of the user, the length of time the user uses the APP, and The proportion of APP push messages clicked by the user to all APP push messages received. The characteristic information is used to subsequently determine whether the information should be sent to the target mobile phone number in the form of APP push messages or in the form of short messages. The characteristic information includes identity information, where the identity information includes, for example, occupation, age, educational background, work background, etc. As users with different identities are under the same other conditions, the possibility of whether to click the APP to push information is Different, so you can use the characteristic information including the identity information of the user, the length of time the user uses the APP and the proportion of the APP push messages clicked by the user to all the received APP push messages to determine the What kind of information transmission strategy the user applies to.

As described in step S2 above, according to a preset high-dimensional vector mapping algorithm, using the feature information, the target mobile phone number is mapped to a designated vector in a high-dimensional virtual space, wherein the high-dimensional virtual space is preset There are multiple standard high-dimensional vectors, and multiple standard high-dimensional vectors are respectively associated with multiple preset information sending strategies. The preset high-dimensional vector mapping algorithm uses the feature information to map the target mobile phone number to a specified vector in the high-dimensional virtual space, for example: assign different sub-information in the feature information to obtain the value The multiple values of are respectively used as the values of the respective sub-vectors of the specified vector, so as to realize the mapping in the high-dimensional virtual space. Wherein, 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. Therefore, it is only necessary to know the standard high-dimensional vector that is closest to the target mobile phone number, and then use the corresponding information transmission strategy to complete the information transmission.

As described in step S3 above, according to a preset vector screening method, multiple temporary vectors are filtered from multiple standard high-dimensional vectors. The preset vector filtering method is, for example, according to the formula:

Calculate the length Lc of the designated vector, where C is the designated vector, Ci is the i-th component vector of the designated vector C, and the designated vector C has m component vectors; according to the formula:

Calculate the length Lp of the standard high-dimensional vector, where P is the p-th standard high-dimensional vector, Pi is the i-th component vector of the p-th standard high-dimensional vector, and the p-th standard high-dimensional vector has a total of m Sub-vectors; according to the formula: length difference=|Lc-Lp|, multiple length differences between the specified vector and the multiple standard high-dimensional vectors are calculated separately, and the length difference is less than a preset difference value The threshold selection rule selects multiple temporary vectors from the multiple length differences. In this way, a temporary vector closer to the specified vector is selected.

As described in step S4 above, a plurality of first distances are calculated according to a preset distance calculation method, where the first distance is the distance between the designated vector and the temporary vector. According to the preset distance calculation method, the way to calculate multiple first distances is, for example: according to the formula

A plurality of first distances DIS are calculated, wherein the first distance DIS is the distance between the designated vector and the temporary vector, where C is the designated vector, and Ci is the i-th of the designated vector C Partial vector, the specified vector C has a total of m part vectors, D is a temporary vector, Di is the i-th part vector of the temporary vector D, and the temporary vector D has a total of m part vectors. Wherein, the maximum value of the first distance is 1, and the closer the value of the first distance is to 1, it indicates that the corresponding temporary vector is more similar to the specified vector.

As described in step S5 above, it is determined whether a plurality of the first distances are all less than a preset distance threshold. The first distance reflects the degree of similarity between the designated vector and the temporary vector, but if the values of multiple first distances are not large, even if the largest distance among the multiple first distances is found, its corresponding The similarity between the temporary vector and the specified vector is still low. Therefore, this application adopts a preset distance threshold method to eliminate the misjudgment caused when multiple values of the first distance are not large.

As described in step S6 above, if a plurality of the first distances are not uniformly smaller than the preset distance threshold, then according to the corresponding relationship of the first distance-temporary vector-information sending strategy, the specified value corresponding to the first distance with the largest value is obtained Information sending strategy, and sending information to the target mobile phone number according to the specified information sending strategy. The first distance is related to the temporary vector (ie, the standard high-dimensional vector), and the standard high-dimensional vector is related to the information transmission strategy. Therefore, the corresponding designated information transmission 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 means that the designated information sending strategy is most suitable for the user. Accordingly, information is sent to the target mobile phone number according to the specified information sending strategy. The specified information sending strategy is, for example, whether to use APP push message mode; whether to use short message sending mode; when to send information, etc.

In one embodiment, the step S2 of mapping the target mobile phone number to a designated vector in a high-dimensional virtual space by using the characteristic information according to a preset high-dimensional vector mapping algorithm includes:

S201. Divide the characteristic information into identity information and other information except the identity information.

S202: Map the identity information and the other information into a first partial vector group A and a second partial vector group B, respectively, according to a preset correspondence between information and vectors;

S203: Obtain the influence parameter group k1-kn of the first partial vector group A on the second partial vector group B according to the preset influence relationship of the first vector group on the second vector group;

S204. According to the formula: C=(A,k1b1,k2b2,...,knbn), calculate the designated vector C, wherein the second sub-vector group B is (b1,b2,...,bn), and n is greater than 0 Integer.

As described above, it is realized that the target mobile phone number is mapped to the designated vector in the high-dimensional virtual space by using the characteristic information according to the preset high-dimensional vector mapping algorithm. This application divides the characteristic information into identity information and other information other than the identity information. Due to the specificity of the population, different identities deal with APP push information in different ways, for example, the A-identity population They are more keen to click on the APP to push information, and the B-identity people hate APP push information, etc., so the identity information will have a potential impact on other information besides the identity information. Accordingly, this application adopts the preset influence relationship of the first vector group to the second vector group to obtain the influence parameter group k1-kn of the first sub-vector group A on the second sub-vector group B; according to the formula: C=(A,k1b1,k2b2...knbn), the specified vector C is obtained by calculation, wherein the second vector group B is composed of n component vectors b1, b2,..., bn, which makes the generation of the specified vector more accurate. The influencing parameter group k1-kn can be pre-generated in any manner, for example, pre-generated by analyzing identity information for information other than the identity information, and can be based on a machine learning model and adopt a supervised learning method. To analyze to obtain the influence parameter group.

In one embodiment, the step S3 of selecting multiple temporary vectors from multiple standard high-dimensional vectors according to a preset vector screening method includes:

S301. According to the formula:

Calculate the length Lc of the designated vector, where C is the designated vector, Ci is the i-th component vector of the designated vector C, and the designated vector C has a total of m component vectors;

S302. According to the formula:

Calculate the length Lp of the standard high-dimensional vector, where P is the p-th standard high-dimensional vector, Pi is the i-th component vector of the p-th standard high-dimensional vector, and the p-th standard high-dimensional vector has a total of m Sub-vector

S303. According to the formula: length difference=|Lc-Lp|, multiple length differences between the designated vector and the multiple standard high-dimensional vectors are calculated respectively, and the length difference is less than a preset difference threshold value. The selection rule is to select a plurality of temporary vectors from the plurality of length differences.

As described above, according to the preset vector screening method, multiple temporary vectors are filtered from multiple standard high-dimensional vectors. The length Lc of the designated vector refers to the distance between the end point and the start point of the designated vector in the high-dimensional virtual space. If there is a standard high-dimensional vector that is similar to the specified vector, then the length of this standard high-level vector must be the same or similar to the length of the specified vector. According to this, according to the formula: length difference = |Lc-Lp|, calculate separately Obtain multiple length differences between the designated vector and the multiple standard high-dimensional vectors, and select multiple temporary differences from the multiple length differences according to the selection rule that the length difference is less than a preset difference threshold. vector. Thus, the temporary vectors are initially selected to reduce the total computational burden.

In one embodiment, the step S4 of calculating a plurality of first distances according to a preset distance calculation method, wherein the first distance is the distance between the designated vector and the temporary vector includes:

S401. According to the formula:

A plurality of first distances DIS are calculated, wherein the first distance DIS is the distance between the designated vector and the temporary vector, where C is the designated vector, and Ci is the i-th of the designated vector C Partial vector, the specified vector C has a total of m part vectors, D is a temporary vector, Di is the i-th part vector of the temporary vector D, and the temporary vector D has a total of m part vectors.

As described above, it is realized that multiple first distances are calculated according to the preset distance calculation method. The first distance DIS reflects the degree of similarity between the designated vector and the temporary vector. This application uses the formula:

The method of calculating the first distance can accurately know the degree of similarity between the designated vector and the temporary vector. Furthermore, before the multiple first distances are calculated according to the preset distance calculation method, the following formula is also used:

Calculate the length Lc of the designated vector, where C is the designated vector; according to the formula:

The length Lp of the standard high-dimensional vector is calculated; according to the formula: length difference=|Lc-Lp|, the multiple length differences between the specified vector and the multiple standard high-dimensional vectors are calculated respectively, and according to the In the selection rule that the length difference is less than the preset difference threshold, a manner of selecting multiple temporary vectors from the multiple length differences to perform preliminary screening to select the multiple temporary vectors. Which is based on the formula:

The way to calculate the first distance is to pay more attention to the angle difference between the vectors, while ignoring the numerical difference between the vectors. When multiple temporary vectors are initially filtered out, the values between the vectors are actually The difference is filtered, and the obtained multiple temporary vectors are similar in value to the specified vector. In summary, the multiple first distances calculated by this application are more accurate.

In one embodiment, the plurality of temporary vectors include placeholder vectors and non-placeholder vectors, and part of the component vectors in the placeholder vectors are occupied by copy placeholders, and the copy placeholders are used for copying. And replacing the values of the sub-vectors of the same dimension in the designated vector, the plurality of first distances are calculated according to a preset distance calculation method, wherein the first distance is the difference between the designated vector and the temporary vector The step S4 of the distance between, includes:

S411. Perform a copy replacement operation on the placeholder vector to obtain a placeholder vector after the replacement operation, where the copy replacement operation is used to replace the copy placeholder in the placeholder vector with the designated vector The value of the component vector of the same dimension;

S412. According to the formula:

A plurality of first distances DIS is calculated, wherein the first distance DIS is the distance between the designated vector and the non-occupied vector, or the first distance DIS is the designated vector and the replacement The distance between the occupied vectors after the operation, where C is the designated vector, Ci is the i-th component vector of the designated vector C, the designated vector C has m component vectors in total, and D is the non-occupied vector For the bit vector or the placeholder vector after the replacement operation, Di is the i-th component vector of the vector D, and the vector D has a total of m component vectors.

As described above, it is realized that multiple first distances are calculated according to the preset distance calculation method. Wherein the plurality of temporary vectors include placeholder vectors and non-placeholder vectors, part of the sub-vectors in the placeholder vectors are occupied by copy placeholders, and the copy placeholders are used to copy and replace the specified The value of the component vector of the same dimension in the vector. Therefore, the standard high-dimensional vector can be set as a special placeholder vector to adapt to a situation where some features are not considered. For example, for family vectors (that is, the vector corresponding to users with frequent interactions among family members), the use of copy placeholders can eliminate or reduce the impact of irrelevant features, such as consumption habits and other features (these features have an impact on whether family members interact with each other). Does it frequently have no impact or does not have much impact), you can use copy placeholders to placeholders in the family vector to eliminate or reduce the impact. Then, multiple first distances DIS are calculated, so as to improve the accuracy of the first distance calculation.

In one embodiment, the occupancy vector is a family vector, the value of the first distance corresponding to the family vector is the largest among the plurality of first distances, and the first distance-temporary vector-information is sent according to the first distance The corresponding relationship of the strategies, obtaining the designated information sending strategy corresponding to the first distance with the largest value, and sending information to the target mobile phone number according to the designated information sending strategy S6 includes:

S601. Obtain a designated information sending strategy corresponding to the family vector, where the designated information sending strategy is to send a complete short message or push a complete APP message to only one of the family members of the target mobile phone number user;

S602. Determine whether any member of the family of the target mobile phone number user has received a complete short message or a pushed complete APP message;

S603. If any member of the family of the user of the target mobile phone number has received a short message or a pushed APP message, send a short short message or push a short APP message to the target mobile number, where the short short message is the A part of the complete short message, and the abbreviated APP message is a part of the complete APP message.

As described above, it is realized that according to the corresponding relationship of the first distance-temporary vector-information sending strategy, the designated information sending strategy corresponding to the first distance with the largest value is obtained, and the designated information sending strategy is sent to the target mobile phone number. information. The family vector refers to the vector corresponding to the user whose family members interact frequently. Because of the frequent interaction of family members, generally only one complete message can be sent to realize the information transmission for the whole family (this is because the interaction is frequent, because member A receives After receiving the information, it is likely to convey it to member B; or member A will consider whether all family members need the information after receiving the information, which is equivalent to the realization of information transmission for the entire family), so its corresponding designated information transmission strategy To send a complete short message or push a complete APP message to only one of the family members of the target mobile phone number user. And because the family vector is a special kind of standard high-dimensional vector, it is set as a placeholder vector, thereby eliminating the influence of irrelevant features by copying the placeholder. And in order to further ensure the transmission of information, this application adopts that if any member of the target mobile phone number user’s family has received a short message or a pushed APP message, then a short short message or push a short APP message will be sent to the target mobile number , Wherein the abbreviated short message is a part of the complete short message, and the abbreviated APP message is a part of the complete APP message, which realizes the reminder of the information in the form of abbreviated information. Among them, because the brief information is only a part of the original information, it consumes less communication resources and costs. However, due to the high interaction frequency of family members, the quality of information transmission will not be reduced.

In one embodiment, after the step S5 of judging whether the plurality of first distances are all less than a preset distance threshold, the method includes:

S51. If a plurality of the first distances are all less than a preset distance threshold, obtain historical data of the APP push message of the terminal corresponding to the user, and classify the terminal into a specified level according to the historical data ；

S52: Determine whether the specified level is greater than a preset level threshold;

S53: If the designated level is greater than a preset level threshold, determine whether the terminal has uninstalled the APP;

S54. If the terminal does not uninstall the APP, it is determined whether the terminal maintains a long heartbeat connection with the server corresponding to the APP;

S55. If the terminal maintains a long heartbeat connection with the server corresponding to the APP, send information to the target mobile phone number by means of APP push messages.

As described above, it is realized that if a plurality of the first distances are all less than a preset distance threshold, a multi-process judgment method is adopted to reduce the cost on the premise of ensuring the information arrival rate. Wherein, if a plurality of the first distances are all less than a preset distance threshold, it indicates that the user cannot correspond to the existing information transmission strategy, and therefore, it is necessary to formulate an information transmission strategy in real time. The historical data of clicking APP push messages is, for example, the total number of times of clicking APP push messages, the total number of days, the time length of clicking and reading APP push messages, etc., and then dividing the terminal into designated levels based on this, where the higher the level , Indicating that the terminal is more likely to click on the APP to push messages. Then determine whether the designated level is greater than the preset level threshold; if the designated level is greater than the preset level threshold, determine whether the terminal has uninstalled the APP; if the terminal has not uninstalled the APP, then determine the terminal Whether to maintain a long heartbeat connection with the server corresponding to the APP; if the terminal and the server corresponding to the APP maintain a long heartbeat connection, the APP push message is used to send information to the target mobile phone number, so as to achieve a guaranteed information arrival rate The premise of reducing costs. Further, if the designated level is not greater than a preset level threshold, or if the terminal has uninstalled the APP, or if the terminal and the server corresponding to the APP do not maintain a long heartbeat connection, the message is sent by means of short messages.
