[0002] At present, the derivative indicators of product pricing models are usually completed by four arithmetic operations based on the parameters passed in by the pricing model request interface, the system supplementary parameters, the parameters obtained by the outbound call external system interface, and the constant parameters. The calculation formula is directly solidified in the code, and the parsing process is solidified according to the preset formula, which is not conducive to rapid response to the market and rapid innovation of products. The autonomy of business personnel is low. If the formula changes, the corresponding developers need to be notified to modify the code, which is time-consuming and labor-intensive. Provide a formula configuration interface, configure the interface and parse the formula through the summarized parameter type acquisition mode, which cannot flexibly respond to changes in parameter types and adjust the parsing support for the formula. There is a certain update cost. If business personnel want to expand the acquisition method of new formula parameters, they still need to communicate and discuss with the development and summarize the parameter acquisition method.

[0061] Figure 1 is a schematic diagram of the main process of the indicator processing method according to an embodiment of the present application, such as Figure 1 As shown, the indicator processing method mainly includes the following steps S101 to S105.

[0062] Step S101, receiving an indicator processing request and obtaining a corresponding indicator formula.

[0063] In this embodiment, the execution entity of the indicator processing method (for example, it can be a server) can receive the indicator processing request through a wired connection or a wireless connection. The indicator can be a derivative indicator of the product pricing model, which is used for market-based pricing. After receiving the indicator processing request, the execution entity can obtain the indicator formula carried in the request. The indicator formula can be a formula obtained by performing four arithmetic operations on the parameters passed in by the request interface, the system supplementary recording parameters, the parameters obtained by the outbound external system interface, and the constant parameters. The embodiment of the present application does not specifically limit the types of parameters involved in the indicator formula.

[0064] Step S102, calling the rule engine to identify the symbols in the indicator formula, and determining the return result data according to the symbols.

[0065] Specifically, identifying symbols in the indicator formula includes: identifying four arithmetic operators and comparison symbols in the indicator formula.

[0066] In the four arithmetic operations, it refers to the four basic mathematical operations of addition, subtraction, multiplication and division. Comparison symbols refer to some symbols used in formulas to compare the size or equality of two values, such as equal to (==), not equal to (!=), less than (<), greater than (>), etc. These comparison symbols are used to compare the size or equality of two values, which helps conditional judgment and loop control in the calculation process of indicator formulas.

[0067] Specifically, the return result data is determined according to the symbol, including: in response to the symbol containing four arithmetic operation symbols and comparison symbols, when a logical judgment abnormality is detected based on the four arithmetic operation symbols and the comparison symbols, the four arithmetic operation symbols at the end of the indicator formula are directly deleted and the indicator formula is updated, and the return result data is obtained based on the updated indicator formula.

[0068] When a logical judgment anomaly is detected based on the four arithmetic operation symbols and the comparison symbols, the four arithmetic operation symbols at the end of the indicator formula (i.e., the end of the queue) can be deleted, and then the indicator formula can be updated to adjust the accuracy of the indicator formula, so as to quickly and accurately eliminate the anomaly and improve the accuracy of the indicator processing. Return result data is obtained based on the updated indicator formula, for example, the formula operation result data obtained based on the updated indicator formula (such as the union of parameters, the intersection of parameters, the product of parameters, or the ratio of parameters, etc.) can be used as the return result data.

[0069] Step S103, based on the returned result data, determine the parameters of the indicator formula to be expanded.

[0070] Specifically, based on the returned result data, the indicator formula parameters to be expanded are determined, including: performing similarity matching between the returned result data and each extensible indicator formula parameter in the extensible indicator formula parameter pool, and determining the matched extensible indicator formula parameters as the indicator formula parameters to be expanded.

[0071] After the four arithmetic operations, each parameter in the indicator formula can obtain a new parameter, and the returned result data can be the new parameter. After obtaining the returned result data, the execution subject can calculate the cosine similarity between the returned result data and each extensible indicator formula parameter in the extensible indicator formula parameter pool, and use the extensible indicator formula parameter corresponding to the cosine similarity greater than the preset threshold as the indicator formula parameter to be expanded. This improves the efficiency and accuracy of determining the indicator formula parameters to be expanded.

[0072] Step S104, determining the parameter acquisition type logic corresponding to the indicator formula parameters to be extended, executing the parameter acquisition type logic to acquire the indicator formula parameters to be extended, and then determining the target file corresponding to the indicator formula parameters to be extended.

[0073] The execution subject may determine the parameter acquisition type logic corresponding to the indicator formula parameters to be extended according to the user configuration data corresponding to the indicator processing request, and execute the logic to obtain the corresponding indicator formula parameters to be extended.

[0074] For example, the type of the indicator formula parameter to be expanded can be a parameter that has been used historically, or it can be a newly added parameter. The execution subject can determine the corresponding target file according to the type of the indicator formula parameter to be expanded. Among them, the target file may include a library file and a parent rule file. A library file is a type of file on a computer that provides users with some out-of-the-box variables, functions or classes. A rule set inherits from another rule set. This inheritance relationship can be regarded as the relationship between a parent rule file and a child rule file, where the parent rule file defines some basic rules, and the child rule file expands or specifies them based on these basic rules. Through the parent rule file, it is possible to customize and expand the parameters in the indicator formula according to specific needs while keeping the core logic of the indicator processing unchanged, thereby improving the efficiency and flexibility of indicator processing.

[0075] Step S105, obtaining the target file, and then updating the indicator formula based on the target file and the indicator formula parameters to be extended, and determining the target indicator according to the updated indicator formula.

[0076] The parameters of the indicator formula to be expanded are parsed through the target file to improve the accuracy of the updated indicator formula and the accuracy of the target indicator calculated by the updated indicator formula.

[0077] This embodiment receives an indicator processing request and obtains the corresponding indicator formula; calls a rule engine to identify symbols in the indicator formula and determines the return result data according to the symbols; determines the indicator formula parameters to be extended based on the return result data; determines the parameter acquisition type logic corresponding to the indicator formula parameters to be extended, executes the parameter acquisition type logic to obtain the indicator formula parameters to be extended, and then determines the target file corresponding to the indicator formula parameters to be extended; obtains the target file, and then updates the indicator formula based on the target file and the indicator formula parameters to be extended, and determines the target indicator according to the updated indicator formula. The scalability of the code corresponding to the pricing-related indicators is improved, the development and maintenance costs of indicator processing are reduced, and the efficiency and flexibility of indicator processing are improved.

[0078] Figure 2 is a schematic diagram of the main flow of an indicator processing method according to an embodiment of the present application, such as Figure 2 As shown, the indicator processing method mainly includes the following steps S201 to S207.

[0079] Step S201, receiving an indicator processing request and obtaining a corresponding indicator formula.

[0080] Step S202, calling the rule engine to identify the symbols in the indicator formula, and determining the return result data according to the symbols.

[0081] Specifically, determining the return result data according to the symbol includes: in response to the symbol being a plus sign, piecing together character strings on both sides of the plus sign to obtain the return result data.

[0082] If the symbol in the indicator formula is a plus sign, such as "+", and the symbol is not a numeric value, the string data on both sides of the symbol is directly returned as the return result data, thereby improving the speed and accuracy of indicator formula calculation.

[0083] Step S203, based on the returned result data, determine the parameters of the indicator formula to be expanded.

[0084] If the returned result data does not match any of the extensible indicator formula parameters in the extensible indicator formula parameter pool, that is, the similarities are all less than the preset threshold, the parameter generation model is called to generate corresponding indicator formula parameters to be expanded based on the returned result data, wherein the parameter generation model is used to characterize the correspondence between the input data and the indicator formula parameters, thereby improving the accuracy of determining the indicator formula parameters to be expanded.

[0085] Step S204, determining the parameter acquisition type logic corresponding to the indicator formula parameter to be expanded, and executing the parameter acquisition type logic to acquire the indicator formula parameter to be expanded.

[0086] Step S205, based on the parameters of the indicator formula to be expanded, determine the variables, functions, classes or rules required for parsing the expanded indicator formula.

[0087] Step S206, determining the corresponding target file based on the variable, function, class or rule.

[0088] If the calculation of the parsed extended indicator formula requires a variable, function or class, the corresponding target file is determined to be a library file. If the calculation of the parsed extended indicator formula requires a rule, the corresponding target file is determined to be a parent rule file. By determining the target file by parsing the type of data required by the extended indicator formula, the speed and accuracy of determining the target file can be improved.

[0089] Step S207, obtaining the target file, and then updating the indicator formula based on the target file and the indicator formula parameters to be extended, and determining the target indicator according to the updated indicator formula.

[0090] The embodiments of the present application can improve the scalability of the codes corresponding to pricing-related indicators, reduce the development and maintenance costs of indicator processing, and improve the efficiency and flexibility of indicator processing.

[0091] Figure 3 is a schematic diagram of the main flow of an indicator processing method according to an embodiment of the present application, such as Figure 3As shown, the indicator processing method mainly includes the following steps S301 to S308.

[0092] Step S301, receiving an indicator processing request and obtaining a corresponding indicator formula.

[0093] This indicator can be a derivative indicator of the product pricing model, used for market-based pricing. The indicator formula can be obtained by combining parameters with four arithmetic operations.

[0094] Step S302, calling the rule engine to identify the symbols in the indicator formula, and determining the return result data according to the symbols.

[0095] The execution subject can call the rule engine to exclude text, pictures and other data in the indicator formula, and obtain the symbols in the indicator formula, so as to improve the efficiency and accuracy of identifying the symbols in the indicator formula. The indicator formula is updated by the symbols in the identified indicator formula, and the return result data corresponding to the latest indicator formula is obtained. The return result data can be a combination of parameters.

[0096] Step S303, based on the returned result data, determine the parameters of the indicator formula to be expanded.

[0097] Step S304, determining the parameter acquisition type logic corresponding to the indicator formula parameters to be extended, executing the parameter acquisition type logic to acquire the indicator formula parameters to be extended, and then determining the target file corresponding to the indicator formula parameters to be extended.

[0098] Step S305, obtaining the target file, and expanding the indicator formula based on the indicator formula parameters to be expanded to obtain the expanded indicator formula.

[0099] The execution subject can determine the position identifier carried by the parameter of the indicator formula to be expanded, and insert the parameter of the indicator formula to be expanded into the corresponding position of the indicator formula according to the position identifier to obtain the expanded indicator formula, thereby accurately obtaining the expanded indicator formula.

[0100] Step S306, using the target file to parse the expanded indicator formula to obtain formula parsing data.

[0101] The target file can be the data required for parsing the extended indicator formula. By using the target file to parse the extended indicator formula, the formula parsing data can be accurately obtained for the convenience of subsequent personnel to use, so as to accurately parse the extended indicator formula, reduce the difficulty and cost of indicator processing development and maintenance, and improve the accuracy of indicator processing.

[0102] Step S307, parsing the data based on the formula, generating annotations, and adding annotations to the expanded indicator formula.

[0103] By adding the annotations generated by formula parsing data to the extended indicator formula, it can be more convenient for users to use, thereby improving the indicator processing efficiency and development and dimension difficulty. After adding annotations to the extended indicator formula, the indicator formula is updated to obtain the updated indicator formula, that is, the updated indicator formula carries the annotations.

[0104] Step S308, determining the target indicator according to the updated indicator formula.

[0105] The execution subject can execute the calculation logic according to the annotations carried by the updated indicator formula to obtain the calculation result data, i.e., the target indicator, thereby improving the efficiency and accuracy of determining the target indicator.

[0106] In the embodiment of the present application, in order to meet the needs of product innovation and price management under the conditions of interest rate marketization, realize rapid response to the market, high scalability and flexibility of interest rate pricing, and improve IT's support for price realization, when realizing the processing and calculation of derivative indicators of the product pricing model, the configuration calculation of pricing derivative indicators is quickly realized based on the rule engine, which can better support the rapid innovation of products and improve the market response speed. The derivative indicators of the product pricing model are obtained by performing four arithmetic operations based on the parameters passed in by the pricing model request interface, the system supplementary parameters, the parameters obtained by the external system interface for outbound calls, and the constant parameters. Combined with the product advantages of the rule engine, it can flexibly support business expansion and support the parameter acquisition type logic of indicator formulas that cannot be identified at this stage; by reducing the complexity of components that implement complex business logic, it reduces the maintenance and scalability costs of applications, effectively improves the maintainability of complex logic codes, and meets the agile development of indicator formula configuration calculations; operation and maintenance deployment optimization supports the repair of code defects during development or after deployment. For pricing, the main indicator configuration is based on the four arithmetic operations. In terms of code integration, mathematical expressions for parsing are integrated. In terms of specific code implementation, the four arithmetic operations and the preceding comparison symbols are judged and processed. If the symbols contained in the indicator formula are four arithmetic operations and comparison symbols, in abnormal cases, the four arithmetic operators at the end of the queue are directly removed to ensure the accuracy of the indicator formula. If the symbol contained in the indicator formula is a plus sign and is not a numeric value, the result data of two strings is directly returned. In terms of dynamic expansion, combined with the configuration content of the rule engine, the rules and execution library files are defined and configured. The rules of the rule engine can be used to flexibly expand the indicator formula parameters that cannot be recognized at this stage, and the library files and parent rule files can be flexibly and dynamically introduced. For example, when configuring, you can configure rules, types, predefined values, and you can configure the output of debugging information, operation mode, default mode, sequential mode, introduction of library files, and introduction of parent files. Among them, when configuring rules, you can configure the conditions of the rules and whether to loop, etc. When obtaining the parameters of the indicator formula that cannot be identified at this stage, obtain the file to be executed, the currently executed rule, the currently executed file ID (that is, the currently executed file identifier), the currently executed rule prefix name, the return object information, and the expected value, and then execute the judgment process to obtain the filtered field content data that can be output, determine the corresponding type of the field content data to determine the debugging mode information, and then pre-compile the content and store it in the cache of the service class to determine whether to enable logging. If so, provide a log query function for users to perform log queries related to indicator processing.

[0107] The rule engine separates business rules from application logic to reduce operation and maintenance costs. During the troubleshooting process, the business correlation is lower, the reliance on business background knowledge is less, and the code is more versatile and maintainable, which makes it easier for developers to follow up and troubleshoot problems. Technology does not need to worry about business changes, making it more flexible and controllable. By leveraging the flexibility and variability of rules, it is easier to expand the parameter acquisition type logic that supports indicator formulas that are not currently recognized, thereby improving agile R&D efficiency. The introduction of the rule engine effectively improves the maintainability of complex logic code, supports fixing code defects during development or after deployment, and flexibly and dynamically introduces library files and parent rule files to improve development convenience and reduce development costs.
