The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a first embodiment of a method for recommending a financial product according to the present invention, the method for recommending a financial product comprising the steps of:
step S10, acquiring a knowledge graph corresponding to a first user to be recommended, wherein the product knowledge graph comprises a plurality of connection relations between business topics and financial products, each business topic is connected with one or more financial products, the business topics are connected with the financial products through common attribute characteristics, and the financial products are financial products purchased or browsed by the first user.
In the present embodiment, the execution subject is a recommendation apparatus for financial products, and for convenience of description, the apparatus is hereinafter referred to as a recommendation apparatus for financial products. The knowledge graph of the user to be recommended is stored in the device. The user to be recommended is defined as the first user. The knowledge graph comprises a plurality of business topics and the connection relations of the financial products, each business topic is connected with one or more financial products, and the financial products are the financial products purchased or browsed by the first user. The business theme is connected with the financial product through common attribute characteristics. As shown in FIG. 1, financial product 1 is connected to the business topic "robust profit" through attribute features "T +1 Account" and "equity type". The business theme is generated by extracting the attribute characteristics of different financial products. For example, a business topic with a high return rate is defined as a business topic with a number of repeated throws greater than 1000 and a proportion of repeated throws greater than 10%, and a business topic with a low return rate is defined as a business topic with a maximum return of less than 1% in the last year and a maximum return of less than 2% in the last three years. The knowledge-graph may be transmitted to the device by an external device or generated by the device based on the operation information of the first user for each financial product. The operation information includes information of financial products browsed and purchased by the user. The operation information includes information of the first user on viewing, sharing, paying attention to, placing an order, purchasing and the like of the financial product.
Step S20, determining a target parameter corresponding to each business topic according to the knowledge graph, wherein the target parameter comprises at least one of a first number of attribute features, a second number of paths and operation information of the first user, and the paths are connection paths of the financial products and the business topics.
After determining the knowledge-graph, the apparatus may determine a target parameter corresponding to each business topic, where the target parameter includes at least one of a first number of attribute features, a second number of paths, and operation information of the first user. The first number is the number of attribute features of the business topic connection. The path is a connection path of the financial product with the business theme. Referring to fig. 1, the financial product 1 forms a path of "robust profit" by connecting two arrows of the business topic "robust profit" to account "through the feature attribute" T + 1.
And step S30, determining a target recommendation score corresponding to each service topic according to the initial recommendation score corresponding to each service topic and the target parameter.
Each business topic has a corresponding initial recommendation score, the initial recommendation score w0Can be flexibly configured and intervened according to market conditions and business experiences, and w0Can take values between 0 and 1. That is, the initial recommendation score may be set by a customer manager of the financial product institution, and the set initial recommendation score may be stored in the device. The device obtains the initial recommendation score corresponding to each business topic, and corrects the initial recommendation score based on the target parameters to determine the target recommendation score corresponding to the business topic. For example, the target parameter includes a first number of attribute features corresponding to the business topic, and if the number of the attribute features connected to the business topic is larger, the business topic is more appropriate for the first user to purchase a financial product, so that a correction value can be determined by the first number, and the larger the first number is, the larger the correction value is, so that the larger the target recommendation score obtained by correcting the initial recommendation score based on the correction value is.
Step S40, determining a target business theme in each business theme according to the target recommendation score, and pushing product information of the financial product related to the target business theme to a terminal related to the first user, wherein the target recommendation score of the target business theme is larger than a preset score.
After the target recommendation scores corresponding to the business topics are determined, whether the first user has purchase intention on the financial products related to the business topics needs to be estimated based on the target recommendation scores. The device stores a preset score, and if the target recommendation score is larger than the preset score, the business theme corresponding to the target recommendation score can be determined to be the business theme which is interested by the user. In this regard, the device determines the service theme with the target recommendation score larger than the preset score as a target service theme couple, and then pushes the product information of the financial product associated with the target service theme to the terminal associated with the first user.
In the technical scheme provided by this embodiment, a knowledge graph corresponding to a user to be recommended is obtained, target parameters such as the number of attribute features, the number of paths, operation information of the user and the like corresponding to each service topic are determined according to the knowledge graph, a target recommendation score corresponding to each service topic is determined according to an initial recommendation score and the target parameters corresponding to each service topic, and a target service topic is determined according to the target recommendation score, so that product information of a financial product related to the target service topic is pushed to a terminal related to the user. In the invention, the target business theme which is expected by the user is determined by the knowledge map obtained by the financial products purchased or browsed by the user, so that the financial products related to the target business theme are recommended to the user, the recommendation accuracy of the financial products is improved, and the recommendation precision of the financial products is higher.
Referring to fig. 3, fig. 3 shows a second embodiment of the method for recommending financial products according to the present invention, wherein step 30 includes:
in step S301, the maximum number is determined among the respective first numbers.
In this embodiment, the target parameter includes a first number. The apparatus determines a correction value based on the first amount, and obtains a target recommendation score by correcting the initial recommendation score based on the correction value, the correction value being defined as a first correction value. Specifically, the device determines the maximum number in each first number, and the maximum number represents the service topic with the most attribute features of the connection.
Step S302, determining a first correction value corresponding to each business topic according to the maximum number and a first number corresponding to each business topic, wherein the first number and the first correction value are in a positive correlation relationship.
The device determines a first correction value corresponding to each business topic based on the first number corresponding to each business topic by the maximum number. The larger the number of the attribute features connected with the service theme is, the larger the first correction value corresponding to the service theme is, that is, the first number and the first correction value are in positive correlation.
Step S303, according to the first correction value corresponding to the service theme, the initial recommendation score corresponding to the service theme is corrected to obtain a target recommendation score corresponding to the service theme.
After the first correction value corresponding to each business theme is determined, the initial recommendation score of the business theme can be determined to be corrected based on the first correction value of the business theme, and the target recommendation score corresponding to the business theme is obtained.
Specifically, the target recommendation score obtained by correcting the initial recommendation score by the first correction value can be represented by the following formula:
W＝W0X(1-log10 tnum/log10 tmax_num)
wherein, w0Is the initial recommendation score, W is the target recommendation score, (1-log)10 tnum/log10 tmax_num) Is a first correction value, tnumIs a first number, tmax_numIs the maximum number.
In the technical solution provided in this embodiment, the apparatus determines the maximum number among the first numbers, determines the first correction value corresponding to each service topic according to the maximum number and the first number corresponding to each service topic, and corrects the initial recommendation score corresponding to the service topic based on the first correction value of the service topic, thereby accurately obtaining the target recommendation score corresponding to the service topic.
Referring to fig. 4, fig. 4 shows a third embodiment of the method for recommending financial products according to the present invention, wherein step S30 includes:
step S304, determining the path weight of each path corresponding to the business theme according to the second quantity corresponding to the business theme, wherein the path weight and the second quantity are in a negative correlation relationship.
In this embodiment, the target parameter includes a second number of paths of the business topic connection. The knowledge graph includes multiple paths, and each business topic connects multiple paths, for example, the "robust profit" in fig. 1 connects 6 attribute features, so there are six paths for the "robust profit".
The device determines the path weight of each path based on the second number of paths connected by the service subject, and the larger the second number is, the pathsThe larger the path weight, i.e. the path weight is inversely related to the second number. The path weight may be given by
Characterization, p _ numjA second number of paths contained by the traffic topic numbered j. For example, there are six paths for "robust yield," and the path weight for each path for "robust yield" is 1/6.
Step S305, determining the length of each path, and determining the product of the length of the path and the path weight to obtain a value corresponding to the path.
Each path has a corresponding length. For example, in FIG. 1 "robust yield" connected to "monetary", the length of this path is 2; the financial product connects "T +1 to account" and "T +1 to account" connecting "robust profit", then the length of this path is 3. The apparatus determines the length of each path, and obtains a value corresponding to the path by determining the product of the length of the path and the path weight.
Step S306, determining a second correction value corresponding to the business theme according to the sum of the numerical values corresponding to the paths corresponding to the business theme.
The device can determine a second correction value corresponding to the business theme based on the sum of the numerical values corresponding to all paths of the business theme. It can be understood that, the fewer the paths of the business topic, the greater the path weight, the greater the second correction value of the business topic, and thus the greater the target recommendation score.
Step S307, according to the second correction value corresponding to the service theme, the initial recommendation score corresponding to the service theme is corrected to obtain a target recommendation score corresponding to the service theme.
The device can correct the initial recommendation score to obtain the target recommendation score based on the first correction value and the second correction value. Specifically, the target recommendation score may be characterized by the following formula:
wherein the content of the first and second substances,
is the sum of the numerical values corresponding to each path of the service theme connection.
In the technical scheme provided by this embodiment, the second number of the device service theme paths determines the second correction value corresponding to the service theme, so that the initial recommendation score is corrected according to the second correction value to obtain an accurate target recommendation score.
Referring to fig. 5, fig. 5 shows a fourth embodiment of the method for recommending financial products according to the present invention, wherein step S30 includes:
and step S308, acquiring the operation behavior of the first user on each path according to the operation information.
In this embodiment, the target parameter includes operation information of the first user. And the device acquires the operation behavior of the first user on each path according to the operation information. The operation behaviors comprise operations of weighting, checking, sharing, paying attention and hanging lists. The device may configure corresponding behavior weights for different operational behaviors. In this regard, the apparatus determines, based on the operation information, an operation behavior of the first user on the financial product, and each attribute feature entered into the product has a corresponding operation behavior, so that the operation behavior of the attribute feature connected to the business topic is the operation behavior of the path where the attribute feature is located.
Step S309, determining a behavior weight corresponding to the path according to the type of the operation behavior corresponding to the path.
Each operational behavior may set a corresponding behavior weight, and thus, the apparatus may determine a behavior weight corresponding to the path based on the type of the operational behavior of the path.
Step S310, determining a third correction value corresponding to the business theme according to the sum of the behavior weights corresponding to each path of the business theme.
Step S311, according to the third correction value corresponding to the service theme, the initial recommendation score corresponding to the service theme is corrected to obtain the target recommendation score corresponding to the service theme.
The device obtains the behavior weights corresponding to each path of the business theme, so that the sum of the behavior weights of each path of the business theme is determined as a third correction value of the business theme, and the device corrects the initial recommendation score according to the third correction value to obtain a target recommendation score.
In this embodiment, the apparatus may correct the initial recommendation score by the first correction value, the second correction value, and the third correction value to obtain a target recommendation score, where the target recommendation score may be represented by the following formula:
where b is the behavior weight of the operational behavior of the path,
is the sum of the behavior weights of the various paths of the traffic topic.
In the technical scheme provided by this embodiment, the device obtains the operation behavior of the first user for each path based on the operation information of the user, determines the behavior weight corresponding to the path according to the type of the operation behavior corresponding to the path, determines a third correction value according to the sum of the behavior weights of each path of the service theme, and finally corrects the initial recommendation score accurately according to the third correction value of the service theme to obtain the target recommendation score of the service theme.
Referring to fig. 6, fig. 6 shows a fifth embodiment of the method for recommending financial products according to the present invention, wherein step S30 includes:
step S312, operation information of each second user is obtained, where the first user is any one of the second users.
In this embodiment, the target parameter includes operation information of the first user. The device needs to determine the correction value based on the heat of the business topic. Specifically, the device acquires operation information of each second user, where the second user is a user corresponding to all accounts stored in the device. The first user is any second user.
Step 313, determining the user operation times of each attribute feature corresponding to the service theme according to the operation information corresponding to each second user.
Step S314, determining the heat value of the business theme according to the user operation times of each attribute feature corresponding to the business theme.
The operation information is the operation information of the second user on the attribute characteristics of the second financial product, so the device can determine the user operation times of each attribute characteristic of each business theme according to the operation information of each second user. For example, it is determined that the financial product has been operated by 100 users according to each operation information, the number of user operations of the attribute feature corresponding to the financial product may also be 100, that is, the number of user operations of the attribute feature of the financial product connected by the service theme is also 100. The device can calculate the total user operation times of the business theme based on the user operation times of each attribute feature of the business theme, and can determine the heat value of the business theme through the total user operation times, wherein the heat value can be normalized, namely the value of the heat value is between 0 and 1.
Step S315, determining a fourth correction value corresponding to the business theme according to the heat value corresponding to the theme business, wherein the heat value and the fourth correction value are in positive correlation.
