Fig. 1 is a schematic structural diagram of an embodiment of a decision system in the present invention. The decision making system comprises a database, at least one external service interface, at least one rule engine and a rule base. In the invention, a plurality of rule files are stored in the rule base, and the rule engine is used for calling the rule files in the rule base to make a decision on input data. The decision method based on the rule file is applied to the decision system.
Fig. 2 is a schematic flow chart of an embodiment of a rule-file-based decision method according to the present invention, and fig. 2 is a schematic flow chart. The decision method based on the rule file comprises the following steps:
201. a first operation command and first data are acquired.
In this embodiment, the first operation command is a string of characters. The first operation instruction may be a numeric string, an alphabetic string, or both, and is not limited herein. The decision-making system provides a plurality of operation options for a user, and an operation command corresponding to each operation option is predefined in the decision-making system. Each operation option provided by the decision-making system also has a corresponding relation with each external service interface in the decision-making system. And the external service interface corresponding to the operation option corresponding to the first operation command receives the first operation command and first data input by a user.
In this embodiment, the first data is data required by the decision system to execute the operation command for decision making. Specifically, the first data includes external data and internal data, where the external data is basic information input by a user and received by the external service interface, and the internal data is related data searched by the external service interface in the database according to the external data. For example, the basic information is a first user account registered in the preset application program, and the database of the rule engine stores related record data logged in the preset application program by using the first user account. After receiving the first user account, the external service interface searches the record data in the preset application program corresponding to the first user account in the database according to the first user account. Or, the basic information is an identity card number or a mobile phone number, and the personal identity card number or the mobile phone number and corresponding personal related data are stored in a database of the rule engine. After receiving the identity card number or the mobile phone number, the external service interface searches personal related data corresponding to the identity card number or the mobile phone number from the database.
When the user uses the decision-making system, after inputting the basic information, the user selects the operation options of the basic information. And an external service interface corresponding to the operation option in the decision system receives the basic information and the operation option, uses the basic information and the related data inquired according to the basic information as first data, and uses an operation command corresponding to the operation option as a first operation command.
202. And determining a first rule file corresponding to the first operation command, wherein a rule language is configured in the first rule file.
In this embodiment, the decision system is provided with at least one rule engine, where each rule engine is respectively configured to invoke a rule file in a rule base to make a decision on data. Specifically, the rule file is configured with a rule language and describes conditions required for returning different results. Optionally, at least two rule engines are arranged in the decision making system to reduce the flow pressure. Different rule files in the rule base correspond to different operation commands. After an external service interface in the decision system acquires first data and a first operation command, a rule engine is randomly selected, and the acquired first data is sent to the rule engine, so that the rule engine calls a first rule file corresponding to the first operation command to make a decision on the first data.
There are various methods of determining the first rule file corresponding to the first operation command.
Optionally, the decision system further stores a preset rule file access protocol table, where the preset rule file access protocol table stores an operation command set, and a rule file access path and a rule file interface credential corresponding to each operation command in the operation command set. The rule file access path and the rule file interface certificate are used for assembling access parameters, and the corresponding rule file can be accessed according to the access parameters. Optionally, the regular file access path is a Uniform Resource Locator (URL).
Determining the first rule file corresponding to the first operation command includes: inquiring a rule file access path and a rule file interface certificate corresponding to the first operation command according to a preset rule file access protocol table; and determining a first rule file corresponding to the first operation command according to the rule file access path and the rule file interface certificate. Specifically, the external service interface assembles the first data, the rule file access path and the rule file interface certificate into an access parameter according to an engine protocol, and sends the access parameter to the selected rule engine.
203. And adopting the first rule file to make a decision on at least part of the first data, and returning a first decision result when the at least part of the first data meets a first condition.
And after receiving the access parameters, the rule engine determines a first rule file according to the rule file access path in the access parameters and the rule file interface certificate, and calls the first rule file to make a decision on first data in the access parameters. Specifically, the rule engine compares the first data with a first condition described in the rule file, and returns a first decision result if the first data satisfies the first condition. Optionally, at least two conditions are described in the rule file, where each condition corresponds to a decision result. And the rule engine compares the first data with all conditions in the rule file in sequence and returns a decision result corresponding to the condition met by the first data.
And after the rule engine decides the first data to obtain a decision result, sending the decision result to the external service interface so that the external service interface displays the decision interface to the user. Optionally, in this embodiment, the decision result is further stored in a database, so as to record the decision history of the decision system.
In the embodiment, the rule engine in the decision system decides the data by adopting the rule file, and because the structure of the rule file only has a simple rule language like 'where … the …' (Chinese: when … is equal to …), no cycle and no cycle are needed, the data only needs to be put into the rule language when the decision is made on the data, and only the newly added variable needs to be put into the rule language when the newly added variable is needed in the data, the code does not need to be rewritten, and the structure is simple.
Optionally, as shown in fig. 3, fig. 3 is a schematic flowchart of another embodiment of the decision method based on a rule file according to the present invention. Different from the embodiment shown in fig. 2, in this embodiment, before the step 203 uses the first rule file to make a decision on the first data, the rule file-based decision method of the present invention further includes:
301. and querying a parameter format and an operation instruction corresponding to the first operation command according to a first preset table.
302. And checking whether the first data conforms to the parameter format corresponding to the first operation command.
In this embodiment, a first preset table is stored in the decision making system, and an operation command set, and a parameter format and an operation instruction corresponding to each operation command in the operation command set are stored in the first preset table.
Optionally, in this embodiment, the parameter format corresponding to the first operation command includes a field name set. And checking whether the first data conforms to the parameter format corresponding to the first operation command, specifically, checking whether the first data includes a field name set corresponding to the first operation command, and if so, determining that the first data conforms to the parameter format corresponding to the first operation command.
For example, the parameter format corresponding to the first operation command includes a field name set of { userid, provnum, isactive }, where userid is used to indicate a registered account number of the user in a preset application, provnum is used to indicate a province number that the user has logged in, and isactive is used to indicate whether the user is active. And when the field name set is included in the first data, determining that the first data conforms to the parameter format corresponding to the first operation command.
Further, optionally, the parameter format corresponding to the first operation command further includes a field length of each field name in the field name set, and checking whether the first data conforms to the parameter format corresponding to the first operation command, specifically, the method further includes: when the first parameter set is determined to contain the field name set corresponding to the first operation command, checking whether the length of the parameter value of each field name in the first data does not exceed the field length of the field name, and if so, determining that the first data conforms to the parameter format corresponding to the first operation command. Therefore, the data format adopted by the first rule language during decision making can be ensured to be correct, and errors are avoided.
For example, in the parameter format corresponding to the first operation command, the field length limit corresponding to userid is 255, the field length limit corresponding to provnum is 8, and the field length limit corresponding to isactive is 8. After the first data is obtained, whether the field length of the parameter value of the userid exceeds 255, whether the field length of the parameter value of the provnum exceeds 8, and whether the field length of the parameter value of the isactive exceeds 8 are checked, and if not, the first data is determined to accord with the parameter format corresponding to the first operation command.
Further, optionally, in the decision method based on the rule file according to this embodiment, when it is determined that the first data does not conform to the parameter format corresponding to the first operation command, the operation on the first data is stopped, and an error is prompted to occur. The rule engine may prompt the user of the error through text or voice, which is not limited herein.
303. And when the first data is determined to accord with the parameter format corresponding to the first operation command, processing the first data according to the operation instruction.
In this embodiment, there may be a plurality of operation instructions corresponding to the first operation command.
Optionally, the operation instruction corresponding to the first operation command includes a field type of each field name in the field name set, where the field type is used to indicate whether the field name is required for the first rule file decision.
And when the first data is processed according to the operation instruction, selecting a field name required by first rule file decision from a field name set of the first data according to a field type corresponding to the field name in the first data. For convenience of description, the selected field names are used as a core field name set, and the core field name set comprises the field names required by the first rule file decision in the first data. And deciding the parameter values of the field names in the decision field name set by adopting the first rule file.
Specifically, when the external service interface assembles the first data, the rule file access path and the rule file interface certificate into the access parameter according to the engine protocol, the field names in the core field name set and the parameter values of the field names are assembled into the access parameter, and the access parameter is sent to the rule engine. And the rule engine calls a first rule file to make a decision on the parameter values in the core field name set. In this way, unnecessary parameters may be avoided from being sent to the rules engine.
Optionally, the operation instruction corresponding to the first operation command includes a warehousing instruction of each field name in the field name set, where the warehousing instruction is used to instruct whether to store the field name in a database. When the first data is processed according to the operation instruction, when the warehousing instruction corresponding to the field name in the first data is used for indicating that the field name is stored in the data, the parameter value of the field name is stored in a database so as to record the decision history of the rule engine.
In this embodiment, by using a first preset table to query a parameter format and parameter operation corresponding to the first operation command, when it is checked that first data conforms to the parameter format corresponding to the first operation command, the first data is processed according to the operation instruction; therefore, when the variables required by the decision making of the rule file are changed, the code does not need to be changed, and only the first preset table needs to be modified, so that the maintenance of the decision making system is simpler.
In this embodiment, optionally, the external service interface needs to record at least part of the parameters and the decision result in the first data in the database. There are various recording methods, one of which is described below.
Optionally, the decision system further stores a second preset table, where the second preset table stores an operation command set and an entry path corresponding to each operation command in the operation command set, and the entry path includes a database name, a table name, and a sub-database and sub-table manner. And after the external service interface acquires the decision result and the first data, packaging the decision result and the first data. Optionally, the external service interface encapsulates the decision result and the first data by using SQL language.
And the external service interface inquires an entry path corresponding to the first operation command according to the second preset table, and stores the packaged decision result and the first data into a database according to the entry path.
In order to facilitate understanding of the present invention, the following describes an example of the rule-file-based decision method according to the present invention with a specific application scenario.
Fig. 4 is a schematic structural diagram of a decision system according to an embodiment of the present invention. In this embodiment, the decision system is specifically a credit investigation decision system, and is configured to execute a rule file-based decision method. Specifically, the decision system comprises an interface, anti-fraud management, a database and a rule engine, wherein the rule engine comprises a rule base, and the anti-fraud management comprises an anti-fraud interface, a first preset table, a preset rule file access protocol table and a second preset table.
In this embodiment, before the first user loans, the merchant needs to use the decision-making system to make a decision on the data of the first user to obtain the credit rating of the first user, so as to evaluate whether the first user is fraudulent according to the credit rating of the first user. Specifically, the merchant firstly inputs a registered account number of the first user in a preset application program on an interface of the decision system and selects an operation option for acquiring the credit rating of the first user. And after the decision-making system receives the selection of the operation option, the decision-making system calls an anti-fraud interface in anti-fraud management. The anti-fraud interface obtains the registered account, specifically, the registered account is zhangsan in this embodiment. The anti-fraud interface takes the registered account as a parameter value of a field name userid; and searching the related data of the registered account in a database according to the registered account.
Specifically, in this implementation, the relevant data of the registered account in the database includes the number of the provinces that the registered account has logged in and whether the registered account is active. The anti-fraud interface takes the provincial number as a parameter value of a field name provnum and takes a result of whether the registered account is active as a parameter value of a field name isactive. Here, the value of isactive is 1 when the user is an active user, and the value of isactive is 0 when the user is not an active user. Specifically, in this embodiment, the anti-fraud interface uses the field name of userid, inactive, 1, and prevnum, 10 as the first data, and obtains the first operation command corresponding to the operation option selected by the merchant for obtaining the credit level of the first user, where the first operation command is 10001 in this embodiment.
The anti-fraud interface looks up the parameter format and the operation indication corresponding to 10001 shown in the following table in the first preset table according to the first operation command 10001.
When the field type is 0, the corresponding field name is not the field required by the rule file decision, and when the field type is 1, the corresponding field name is the field required by the rule file decision; when the warehousing indication is 0, the corresponding field name is not required to be stored in the database, and when the warehousing indication is 1, the corresponding field name is required to be stored in the database.
When the anti-fraud interface detects that the first data includes all the field names in the table and the length of the parameter value of each field name in the first data does not exceed the length of the corresponding field, it is determined that the first data conforms to the parameter format corresponding to the operation command 10001.
The anti-fraud interface queries, according to the first operation command 10001, a rule file access path and a rule file interface credential corresponding to 10001 shown in the following table from a preset rule file access protocol table.
| Operating commands | Regular file access path | Rule file interface voucher |
| 10001 | url1 | spdb_comm |
The anti-fraud interface packages the inactive 1, the provnum 10, the spdb _ comm and the url1 in the first data according to the format agreed by the engine protocol to generate the access parameter. The access parameters are then sent to the rules engine.
And the rule engine determines a rule file from the rule base according to the spdb _ comm and the url1 in the access parameters, calls the rule file to make a decision on the data "inactive 1 and prevnum 10", and obtains a decision result, wherein the decision result is the credit rating of the first user. And the rule engine sends the decision result to the anti-fraud interface so that the anti-fraud interface displays the decision result on the interface.
The anti-fraud interface further queries, according to the first operation command 10001, an entry path corresponding to 10001 shown in the following table in the second preset table, where the entry path includes a database name, a table name, and a sub-base and sub-table manner. According to the parameter format and the operation instruction corresponding to 10001 found by querying in the first preset table, the parameter value of the field name provnum does not need to be recorded into the database.
| Operating commands | Name of field | Name of database | Table name | Warehouse and table dividing mode |
| 10001 | userid | A | M | x |
| 10001 | isactive | C | P | z |
And the fraud prevention interface records the userid in the first data into the database according to the entry path corresponding to the userid, and records the isactive 1 into the database according to the entry path corresponding to the isactive.
