Detailed Description
exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic diagram of the main steps of a method for determining a target user according to an embodiment of the present invention.
as shown in fig. 1, the method for determining a target user according to the embodiment of the present invention may be specifically executed according to the following steps:
Step S101: and training a pre-established purchase intention classification model by utilizing the values of a plurality of specific users in at least one preset primary selection dimension to obtain the weight value of each primary selection dimension.
In this step, the specific user refers to a user who has performed the purchase association action for the target commodity once and purchased the target commodity after a certain period of time. The target product, which is an object product, may be any specific product as an application object of the method of the present invention. Illustratively, the purchase correlation behavior may be any of the following: the method includes the steps of searching for a commodity and not purchasing the commodity after a first time period (may be referred to as a search non-purchase behavior for short), accessing a commodity page and not purchasing the commodity after a second time period (may be referred to as an access non-purchase behavior for short), placing the commodity in a shopping cart and not purchasing the commodity after a third time period (may be referred to as a shopping cart non-purchase behavior for short), and entering a commodity settlement page and not purchasing the commodity after a fourth time period (may be referred to as an entry settlement page non-purchase behavior for short), wherein the above time periods can be flexibly set according to actual scenes.
In a specific application, the actual scenario of searching for unpurchased behavior may be: the user listens to a certain commodity but does not know specific information thereof, and searches for it for curiosity. The actual scenario of accessing unpurchased behavior may be: the user would like to fully understand the detailed information of a certain commodity, but abandon the purchase because the function of the commodity cannot completely match the requirement of the commodity or because the price of the commodity is higher. The actual scenario of an unpurchased action of placing a shopping cart may be: the user is mindful of a commodity and has accepted its price, but abandons the commodity because a more suitable alternative appears. The actual scenario of an unpurchased action into a checkout page may be: the user is mindful of a certain item and accepts its price while there are no alternatives, but the item has to be temporarily abandoned since the total price of several items in an order is over the budget. It can be seen that the above four purchase association behaviors can directly reflect the purchase intentions of users with different degrees, and the specific users who have executed the purchase association behaviors and finally make purchases at the later stage are screened out and the characteristics of each specific user are analyzed, so that the specific attributes of the users who are easy to realize purchase conversion (i.e. target users) can be outlined.
generally, the primary selection dimension may be preset according to an application environment. For example, gender, marital status, etc. may be set. In particular, in the embodiment of the present invention, in order to reduce the amount of operations and enhance the system robustness, each of the primary dimensions may be set as a virtual variable (i.e., a dummy variable) whose value can only be 0 or 1. In a specific application, a user characteristic with a plurality of values can be converted into a plurality of virtual variables. For example: the Age characteristics can be converted into the following five primary dimensions Age _1, Age _2, Age _3, Age _4, Age _5, etc.:
wherein, the dimension option represents a plurality of options of a certain primary selection dimension. For example: the dimension options for the "gender" dimension are "male" and "female". A certain value of the user in the initial selection dimension corresponds to a dimension option, and the classification contribution of the dimension option can be reflected.
Although the virtual variables are used as examples in the above, the initial dimensions of the present invention are not limited to the virtual variables. In fact, the initial selection vector may be a variable with any value, and the present invention is not limited in this respect.
in one embodiment, the pre-established purchase intention classification model indicates that the mathematical structure of the model is pre-established, but the model parameters need to be determined through a subsequent training process. The purchase intention classification model is used for judging the purchase probability according to the value of the user in the primary selection dimension, and can be a classification model such as naive Bayes, a decision tree, logistic regression and the like. In this step, a specific user who has performed a search unpurchased behavior, accessed an unpurchased behavior, placed in a shopping cart unpurchased behavior, or entered a settlement page unpurchased behavior may be selected first, and then a value of a certain class of specific users in at least one primary selection dimension is input into the purchase intention classification model for training to obtain a weight value of each primary selection dimension, where the weight value may reflect a classification weight of the primary selection dimension in the purchase intention classification model. Obviously, 4 kinds of purchase intention classification models with different parameters are available for the above 4 kinds of specific users.
The following description will be made by using a logistic regression model. In the logistic regression model, the logistic function is:
Wherein, X is an independent variable, namely a vector formed by values of the initially selected dimension of a specific user; y is a dependent variable and can be 1 or 0, wherein 1 represents purchase after the purchase association behavior is executed, and 0 represents purchase after the purchase association behavior is executed; theta is a vector formed by weighted values corresponding to the primary dimension to be solved, and T represents transposition.
Then, an objective function can be established by applying a maximum likelihood estimation method, and a weight value of each initially selected dimension is determined by utilizing a Newton-Raphson method. The following table shows a plurality of primary dimensions obtained by converting the age characteristics and the weight values thereof determined according to the logistic regression model.
The following table shows values, dimension options and primary dimension weight values of a plurality of primary dimensions obtained by converting the characteristic of 'purchase amount of a user in 3 months'.
step S202: determining a primary selection dimension with a weight value meeting a preset first judgment condition as a high-weight dimension, and acquiring a purchasing tendency score of a user who does not purchase a target commodity according to the high-weight dimension and the weight value thereof; and determining the users with the purchase tendency scores meeting the preset second judgment conditions as target users, and providing purchase guide objects of the target commodities for the target users.
In this step, the first determination condition and the second determination condition may be set according to the application environment. For example, the first discrimination condition may be set to: the weight value of the primary selection dimension is greater than a preset second threshold or one of m (which is a positive integer) weight values of which the weight value of the primary selection dimension is the maximum, that is, the high-weight dimension can be determined according to the following two ways:
the first mode is as follows: taking the primary selection dimension with the weight value larger than a second threshold value as a high weight dimension;
The second mode is as follows: and (4) sorting the weighted values of all the primary selection dimensions in a descending order, and taking the previous m primary selection dimensions as high-weighted dimensions.
And then, acquiring the purchase tendency score of any user who does not purchase the target commodity according to the high weight dimension and the weight value thereof, wherein the purchase tendency score can be used for representing the purchase conversion probability of the user who does not purchase the target commodity. Specifically, the product of the value of the user in each high-weight dimension and the weight value of the high-weight dimension can be calculated, and the sum of all the products is used as the purchase tendency score of the user. If the primary selection dimension is a virtual variable, the purchase tendency score of the user is equal to the sum of the weight values of the high-weight dimensions with non-zero values of the user.
As a preferred scheme, after the high-weight dimension is obtained, for any user who does not purchase a target product, the high-weight dimension with a non-zero value is determined, and a dimension option corresponding to the non-zero value is used as an image label of the user, so that the user with a strong purchase intention is visually marked, and guidance is provided for making a subsequent sales strategy. For example: if the primary dimensions "Age _ 3" and "Sum _ 4" in the previous table are high-weight dimensions, and the values of the user who has not purchased the target product in the two dimensions are both 1 (non-zero values), the corresponding dimension options "35 < Age ≦ 40" and "purchase amount in 3 months >6 ten thousand" may be used as the labels of the user figures.
in one embodiment, after obtaining the purchasing tendency score of the user, the user whose purchasing tendency score meets the second criterion may be determined as the target user. For example: when the resources are abundant, users with purchase tendency scores larger than a preset third threshold value can be taken as target users; when the resources are strained, users with a purchasing propensity score between the third threshold and the fourth threshold (i.e., purchasing propensity scores greater than the third threshold and less than the fourth threshold) may be targeted. This is because: among users with purchase tendency scores larger than the third threshold, users not smaller than the fourth threshold have stronger purchase intentions, and the subsequent purchase conversion cannot be greatly influenced even if the users are not taken as target users (namely, subsequent actions are not performed on the users), so that the users can be excluded from the target users when resources are in shortage; and the users with the purchase tendency scores between the third threshold and the fourth threshold, which have slightly small purchase willingness, can be used as the subjects of the target users and perform subsequent actions specifically to generate purchase conversion.
It is understood that the second determination condition may be set to take a certain percentage of users as target users. For example: when the resources are abundant, the users with the largest purchasing tendency scores of 30% can be used as target users; when the resources are short, the user with the highest tendency score of 5% (the proportion of the user as a whole) may be excluded from the above users, and the remaining users may be the target users.
then, a purchase guide object of the target item (i.e., advertisement information of the target item or a trial) may be provided to the target user to prompt the target user to purchase the target item. It can be understood that the purchasing associated behaviors of the user are mined in the steps, so that the high-weight dimension and the weight value thereof are determined, and the purchasing tendency score of the user is calculated according to the high-weight dimension and the weight value to realize the accurate evaluation of the purchasing desire of the user.
in practical applications, different actions may be performed for target users with different purchasing propensity scores. For example: for target users with purchase tendency scores larger than a preset first threshold, only providing a purchase guide object of a target commodity (because the purchase intention of the target users is strong, only providing the purchase guide object can promote the purchase of the target users); for target users with the purchase tendency scores less than or equal to the first threshold, the purchase guidance object and the promotion strategy of the target products are provided (because the purchase intention of such target users is weaker, the promotion strategies of discounting prices, reaching a certain amount of money, giving off benefits, returning vouchers and the like are further provided to accelerate the purchase conversion of the target products).
Through the steps S101 and S102, the target user can be accurately positioned based on the purchase association behavior directly reflecting the user intention, and the purchase guide object is provided to promote the final purchase, so that the problems of low positioning accuracy and large screening granularity in the prior art are solved.
preferably, in an embodiment, after the purchase guidance object is provided to the target user, feedback data of the target user is obtained, and the weight value of the primary dimension is adjusted by using the feedback data. The feedback data refers to a value of a primary selection dimension of a target user who purchases a target commodity after receiving the purchase guide object.
Specifically, the current purchase intention classification model is further trained by using feedback data to adjust the weight value of the primary dimension, and then the primary dimension of which the adjusted weight value meets a preset third judgment condition is determined as the key dimension. It will be appreciated that the third discrimination condition may be set in a manner similar to the first discrimination condition (only the specific threshold needs to be changed). Since the key dimension is obtained by optimizing the feedback data on the basis of the high-weight dimension, the reliability of the key dimension is higher than that of the high-weight dimension. The key dimensions and their current weight values may then be used to calculate a purchase propensity index (which may function similarly to the purchase propensity score, except that the dimensions used in the calculation may be different) for any user who has not purchased the target item. During specific calculation, if the key dimension is a virtual variable, the sum of the weight values of the key dimensions with non-zero values of the user can be determined as the purchase tendency index. It can be understood that after the key dimension is obtained, the key dimension of the user with the non-zero value can be determined for any user who does not purchase the target commodity, and the dimension option corresponding to the non-zero value is used as the portrait label of the user to guide the formulation of the subsequent sales strategy.
After obtaining the purchase tendency index of the user, the user whose purchase tendency index meets the preset fourth determination condition may be determined as the target user, and the purchase guide object of the target product may be provided thereto. Wherein the fourth discrimination condition acts similarly to the second discrimination condition, and the difference therebetween lies only in the setting of the specific threshold. It is understood that, since the target user at this time is determined based on the feedback data representing the actual purchase situation, the accuracy thereof is higher than that of the target user determined in steps S101 and S102. Through the arrangement, further accurate positioning of the target user and closed-loop optimization of the positioning strategy can be realized.
It will be appreciated that after the second providing of the purchase leader, the corresponding feedback data may continue to be obtained to similarly identify the more accurate target user and provide the purchase leader again, after which the feedback data is obtained again and the purchase leader … … is provided again to repeat the above steps to achieve an iterative optimization of the positioning strategy until the predetermined termination condition is met. Therefore, the invention gradually and clearly outlines the specific attributes of the target user through the multiple iterative processes, thereby effectively promoting the subsequent purchase of the commodity and solving the problem that the positioning strategy can not be improved by utilizing the feedback data closed loop in the prior art.
It should be noted that, in the actual user location process, the purchase intention classification model may be any one of the following models: the model based on the search unpurchased behavior (i.e., the model is trained by the relevant data of the specific user who performed the search unpurchased behavior), the model based on the access unpurchased behavior (i.e., the model is trained by the relevant data of the specific user who performed the access unpurchased behavior), the model based on the built-in shopping cart unpurchased behavior (i.e., the model is trained by the relevant data of the specific user who performed the built-in shopping cart unpurchased behavior), the model based on the built-in settlement page unpurchased behavior (i.e., the model is trained by the relevant data of the specific user who performed the built-in settlement page unpurchased behavior), and any combination of 4 models, for: and respectively setting discrimination conditions for the model based on the search unpurchased behavior and the model based on the access unpurchased behavior to determine a target user, and respectively acquiring corresponding feedback data optimization models after providing a purchase guide object for the target user. The following steps are repeated: discrimination conditions can be respectively set for the 4 models to jointly determine a target user, and feedback data of each model is respectively obtained after the target user is provided with a purchased guide object to optimize the corresponding model.
Fig. 2 is a schematic diagram of a specific implementation of the method for identifying a target user according to the embodiment of the present invention, wherein the steps of identifying a target user and providing a trial product using the 4 models are shown. Specifically, the purchasing behavior data and the order data of the user are firstly cleaned to obtain the 4 specific users and are modeled by the related data of the specific users, and then the high-weight dimension is obtained from the purchasing intention classification model to further determine the purchasing tendency score of the user, so that the target user can be positioned and the trial products can be issued to the target user, and the first issuing of the trial products is completed. And then, when the trial products have surplus, feedback data of the target user is acquired and fed back to the purchase intention classification model after cleaning so as to adjust the weight value of the primary selection dimension, and therefore the more accurate target user is determined. And repeating the iteration process to realize continuous closed-loop optimization of the target user positioning strategy.
According to the technical scheme of the embodiment of the invention, the high-weight dimension and the key dimension can be extracted according to the purchase association behavior of the user, so that the accurate positioning of the target user is realized, the user positioning strategy can be adjusted in a closed loop according to the feedback data, and the effective promotion of the commodity sales volume is finally realized.
Fig. 3 is a schematic diagram of a part of an apparatus for determining a target user according to an embodiment of the present invention.
