Wherein the credit information query request is generated based on a credit application order number entered by a user, such as a credit auditor, in a credit approval system, as shown in fig. 2.
And 102, sending the credit information query request to a first database interface of a server through a first query interface.
Alternatively, the credit information query request may be sent to a corresponding database interface of the server, e.g., the first database interface, through a unified query interface, e.g., the first query interface. The credit information query request may also be sent to a different database interface of the server through a different query interface. The embodiment of the present invention is not particularly limited thereto.
103, receiving and outputting a first credit risk knowledge graph returned by the first database interface through the first query interface, wherein the first credit risk knowledge graph is obtained by querying the graph database through the first database interface.
Wherein the first credit risk knowledge-graph may be generated based on the credit application order numbers and relationship information between the credit application order numbers, wherein nodes of the first credit risk knowledge-graph are generated based on the credit application order numbers, and connection relationships between the nodes of the first credit risk knowledge-graph are generated based on the relationship information between the credit application order numbers.
Specifically, as shown in fig. 3, the node in fig. 3 is the credit application order number, wherein the node located at the bottom left and the largest direction in the credit risk knowledge graph is the center node, i.e., the node with the credit application order number of 2005101010101. The credit risk knowledge graph of the first-layer middle-number node comprising the central node and the periphery of the central node is a first-degree graph, and credit application orders corresponding to the middle-number node are 2005101010102, 2005101010103, 2005101010199, 2005101010106 and 2005101010107 in sequence. By analogy, the credit risk knowledge graph of the second layer of the middle node comprising the central node and the periphery of the central node is a second-degree graph, and the third layer of the middle node comprising the central node and the periphery of the central node is a third-degree graph.
Edges between nodes are generated based on relationship data between different credit application order numbers, which may include applicant phone numbers, family contact phone numbers, other contact phone numbers, address book contact phone numbers, universally unique identifier UUID, blacklist, identification number, and the like. The edges of the knowledge graph display different relationship names according to different defined relationships, and different fields such as 'family contacts, other contacts' and the like can be displayed. The small number node between the central node and the first-degree map is a relation node, and the relation node can be a telephone number, an identity card number and the like.

The predetermined operation may be a single click, a double click, or the like. For example, if the first-degree graph is currently displayed, and the query request is made by manually clicking the corresponding node in the current first-degree graph, the graph database can output the relationship node of the corresponding node. And manually clicking the relationship node again, and outputting a two-degree map corresponding to the relationship node by the map database. Or the first-degree map can be displayed currently, and the corresponding node in the current first-degree map is clicked manually to carry out an inquiry request, so that the map database can directly output the second-degree map of the corresponding node. And currently displaying the second-degree map, manually clicking a corresponding node in the current second-degree map to carry out a query request, and outputting a third-degree map by the map database. The above description is merely exemplary in nature and is not intended to limit the present disclosure.
According to the embodiment of the invention, the credit risk knowledge graph is output in stages, and credit auditors can query the credit risk knowledge graph stage by stage according to requirements, so that the flexibility and the effectiveness of the credit risk knowledge graph are effectively improved. Meanwhile, the time for requesting visualization of the credit risk knowledge graph is not wasted, and the query efficiency is improved.

Wherein the second query interface is different from the third query interface. Specifically, as shown in fig. 2, the credit risk information may be queried through an interface C, and the credit abnormality information may be queried through an interface D.
The server has a database interface corresponding to the terminal device. As shown in fig. 2, a second database interface and a third database interface corresponding to the interface C, D of the terminal device exist in the server, and are used for receiving the query request sent by the query interface.
The credit risk information may include at least one item of credit risk attribute data such as an overdue indicator, an anti-fraud score, a repayment situation, a personal credit score, and the like. The above examples are merely illustrative, and the embodiments of the present invention are not limited thereto.
The credit exception information may be exception data corresponding to an anti-fraud rule formulated according to information in the credit application form number, for example, the credit exception information may also be that an application device, a contact mobile phone number, a unit phone, a unit address, and the like associated with a current loan application order number through an identity card number are greater than a certain threshold, and the credit exception information may also be the number of times that a business person of a credit platform cancels an order for an applicant of a current credit application order within a recent period of time, and the like. The above examples are merely illustrative, and the embodiments of the present invention are not limited thereto.
It should be noted that the credit risk information and/or the credit abnormality information may be stored in a map database, or may be stored in another database, which is not limited in the embodiment of the present invention.
Optionally, the receiving and outputting the credit risk information corresponding to the node in the first credit risk knowledge base map returned by the second database interface of the server through the second query interface includes:
and receiving and outputting credit risk information corresponding to the nodes in the first credit risk knowledge graph returned by the second database interface query node database of the server through a second query interface.

and receiving and outputting the credit abnormality information corresponding to the nodes in the first credit risk knowledge graph returned by the third database interface query node database of the server through a third query interface.
Wherein the node information database may store any information not contained in the graph database. In consideration of the credit application environment, the node information database in the embodiment of the invention is used for storing risk-related information, thereby facilitating quick inquiry of loan risks of credit applicants.
It should be noted that the credit risk information and the credit abnormality information may be from the same node database or may be from different node databases, and this is not specifically limited in the embodiment of the present invention.
The prior art should provide as complete information as possible for loan risk control using a database, which results in a slow knowledge-graph request for a knowledge-graph in credit risk management. In the specific implementation of the invention, the idea that the data is from one database is broken through, the data can not be divided into different databases, the requirement of complete data is met, the speed of knowledge map request in the credit risk management is increased, and the time length of visualization of the knowledge map request in the credit risk management is shortened.
The credit risk prompt is to facilitate a credit auditor to quickly find a risk point, the risks are various, and in order to improve the accuracy of the prompt and fully utilize all data, in the specific embodiment of the invention, in addition to the prompt of the credit risk information and/or the credit abnormal information based on the information in the node information database, the prompt of the credit risk can also be related information in a calculation map database, and a corresponding credit risk prompt is output, so that a risk prompt mechanism is perfected.
Therefore, the specific embodiment of the present invention may further include:
inquiring a graph database, and acquiring node information used for prompting credit risk information and/or credit abnormal information; and performing credit risk information and/or credit exception information prompt processing on the first knowledge graph by using the node information.
That is, in the embodiment of the present invention, the credit risk information and/or the credit abnormality information may be presented based on the data in the map database. As shown in fig. 4, when there is credit abnormality information in the currently displayed knowledge-graph, the graph database may be queried, and the corresponding credit abnormality information is displayed in the credit abnormality information prompt box: the number of the order equipment associated with the current order through the identity card is more than 3, so that the credit auditor is prompted for abnormal information.
In a specific embodiment of the present invention, outputting the credit risk information corresponding to the node in the first credit risk knowledge base and/or outputting the credit abnormality information corresponding to the node in the first credit risk knowledge base is to facilitate a credit auditor to quickly find a risk point and to promote credit approval aging, so that outputting the credit risk information and/or the credit abnormality information may be implemented in various ways, which are respectively described as follows:
in a first mode
The output credit risk information and/or credit abnormality information may be direct display text information.
For example, for a certain node in the knowledge graph, if the node information database records the overdue information of the credit order applicant corresponding to the node, text information can be displayed to the credit auditor for prompting. Such as the text shown in figure 4 displayed in a prompt box above the node of credit order application form number 2005101010107.
Mode two
The output credit risk information and/or credit abnormality information may also be an indirect display. For example, if a blacklist is queried, the corresponding relationship node is marked as black, so that a credit auditor is prompted when observing the knowledge graph. And if other types of prompts can be adopted, the relationship nodes can be flashed with red lights, highlighted and the like.
The output credit risk information and/or the credit abnormality information may be the output credit risk information, may also be the output credit abnormality information, and may also be the output credit risk information and the credit abnormality information, which is not specifically limited in this embodiment of the present invention.
The reason why the credit risk prompt processing is carried out by outputting the credit risk information and/or the credit abnormal information is to facilitate the credit auditor to quickly find the risk points, so that all credit risk display modes and means can be used in the embodiment of the invention, for example, all risk factors can be displayed for a long time. However, considering the number of nodes of the graph and the limitation of the display screen area, the specific embodiment of the present invention may select to display the node information for a predetermined time length.
Optionally, after receiving and outputting the credit risk information corresponding to the node in the first credit risk knowledge graph returned by the second database interface of the server through the second query interface, the method further includes:
displaying the credit risk information for a first predetermined length of time; and/or
After the receiving and outputting the credit abnormality information corresponding to the node in the first credit risk knowledge graph returned by the third database interface of the server through the third query interface, the method further includes:
displaying the credit exception information for a second predetermined length of time.
Specifically, the first predetermined time length and the second predetermined time length may be the same or different, and this is not specifically limited in the embodiment of the present invention. In addition, the first predetermined time length and/or the second predetermined time length may be 10 seconds, 20 seconds, or may be set according to an actual observation requirement of a credit auditor, which is not specifically limited in this embodiment of the present invention.
And displaying the credit risk information and/or the credit abnormal information within a preset time length, and hiding the credit risk information and/or the credit abnormal information outside the preset time length, so that the sight of a credit auditor is not blocked, and the credit auditor can conveniently observe the knowledge graph.
The method comprises the steps of receiving a credit information inquiry request generated based on a credit application form number; inquiring a map database through a first inquiry interface according to the credit information inquiry request and outputting a first credit risk knowledge map; inquiring and outputting credit risk information corresponding to the nodes in the first credit risk knowledge graph through a second inquiry interface, and/or inquiring and outputting credit abnormal information corresponding to the nodes in the first credit risk knowledge graph through a third inquiry interface. Because the data in the credit risk management are subjected to parallel query requests through different query interfaces, the time length of knowledge graph request visualization in the credit risk management is shortened, the usability and flexibility of the knowledge graph are improved, and the observation of credit auditors is facilitated.

the receiving and outputting the first credit risk knowledge-graph returned by the first database interface comprises:
receiving and outputting a first credit risk knowledge graph returned by a target database interface of the server, wherein the hierarchy of the first credit risk knowledge graph is the hierarchy corresponding to the target database interface.
Specifically, as shown in fig. 2, the first query interface includes at least two query interfaces A, B, where query interface a corresponds to a first-degree graph and query interface B corresponds to a higher-level graph. The credit auditor can input the query request through the credit approval system, and the target query interface A or B receives the query request according to the specific information of the query request.
And after the corresponding database interface of the database receives the query request, querying a knowledge graph corresponding to the query request in the database, and outputting the knowledge graph of the corresponding hierarchy of the database interface. For example, the query request input by the user is a request of a one-degree map, and as shown in fig. 2, after the first database interface of the graph database receives the query request, the first database interface performs real-time calculation and sends the one-degree map to the query interface a. If the query request input by the user is a request for a second-degree map, as shown in fig. 2, after receiving the query request, the second database interface of the map database performs real-time calculation, and sends the second-degree map to the query interface B. The above description is merely exemplary in nature and is not intended to limit the present disclosure.
According to the embodiment of the invention, the knowledge graph of the graph database is subjected to hierarchical processing, so that credit auditors can inquire the first-degree graph or the second-degree and third-degree graphs according to requirements, single-stage inquiry pressure is released, the failure of the whole graph caused by the problem of a single inquiry interface is avoided, and the later-stage knowledge graph maintenance and expandability are facilitated. Meanwhile, the time for knowledge graph request visualization is not wasted, and the query efficiency is improved.
