Credit refers to a form of value movement subject to repayment and payment, and generally includes credit activities such as bank deposits, loans, and the like. The loan is necessarily accompanied by risks, and in order to avoid the risks of being open to debt, bad account and the like, the financial risk of the user needs to be evaluated during the credit process to determine whether to provide credit service for the user.
Traditional financial institutions' assessment of financial risk may depend on basic information provided by the user and the experience set by the administrator. Such as basic wages, fixed assets, and work filled by the user, the manager determines the financial risk of the user based on historical experience.

The web page end for providing financial platform browsing and the request end for making financial service request are generally located in the terminal equipment 101, 102, 103.
According to the user financial risk assessment method and device, similarity comparison is carried out on the current user and at least one relationship network based on the basic information; determining a target relation network according to the comparison result; and performing financial risk assessment of the current user according to the characteristic attribute of the target relationship network. The financial risk of the user can be rapidly and accurately estimated comprehensively, and the financial risk probability of an enterprise is reduced.
The user financial risk assessment method of the present disclosure is described in detail below with the aid of specific embodiments.
FIG. 2 is a flow diagram illustrating a method for user financial risk assessment, according to an example embodiment. The user financial risk assessment method 20 is a detailed description of "building the at least one relationship network from the basic information of a plurality of registered users", and the user financial risk assessment method 20 includes at least steps S202 to S208.
As shown in fig. 2, in S202, basic information of a plurality of registered users is obtained, where the basic information includes contact and interaction record information. The basic information of the user can be acquired through the registered data of the user on the financial network platform. It is worth mentioning that, in order to avoid the fraud of the user, when the user performs the registration of the financial network platform, the mobile phone number provided by the user is checked, and after the check is passed, the user is registered. The real-name verification mode of the mobile phone number of the user can fundamentally avoid the fraudulent behavior of the mobile phone number of the user.
In an embodiment, the related information in the contact of the user may be acquired through the mobile phone number of the user, and specifically may include mobile phone numbers of other users held in the contact and call records stored in the contact.
In one embodiment, the interaction record information of the mobile phone number on other platforms can be obtained through registration information of the mobile phone number of the user on other social networks, and the interaction record information can be retrieved in certain communication software through the mobile phone number of the user, so that the relevant other user IDs of the user ID bound with the number and transmitted with the interaction information can be determined.
In S204, an association relationship between the plurality of registered users is determined based on the basic information. The interactive relationship between users in the basic information can determine the incidence relationship between users.
In an embodiment, the obtaining of the relevant information in the contact of the a user through the mobile phone number of the a user may include: and the mobile phone numbers of other users and the call records stored in the contact persons. The mobile phone numbers of other users can be determined from the mobile phone numbers and the call records of other users, the mobile phone numbers of the users B, C and C can be obtained through the mobile phone number of the user A, the mobile phone numbers of the users B, C and C are searched on the current financial platform, and users who are registered on the current financial platform are screened out. An association between a and B users, a and D users, may be determined, for example, by screening that B and D users are also registered users of the current financial platform.
In one embodiment, the registration information of the mobile phone number of the user a on other social networks is obtained through the mobile phone number of the user a, the relevant other user IDs of the user ID bound with the number and transmitted by the interactive information are determined, and then the mobile phone numbers of other users are determined through the other user IDs. And continuously screening on the current financial platform through the mobile phone numbers of other users to determine the association relationship between the users.
The method for determining the incidence relation between the registered users on the current financial network platform through the interaction relation between the users on different communication platforms can avoid the fraudulent behaviors of the users to a great extent.
In one embodiment, determining the associative relationship between the plurality of registered users based on the base information further comprises: determining a number of associations between the plurality of registered users based on the base information. For example, if the association relationship between the a user and the B user only exists in the channel of the contact, if the number of the association relationship between the a user and the B user is 1; if the incidence relation of 2 channels (contact persons and interactive record information) exists between the user A and the user B, the number of the incidence relation between the user A and the user B is 2.
In one embodiment, the association relationship between users may also include other relationships, such as two users having an edge when they have a phone call or a text message, or two people having an invitation or a contact, or sharing the same wifi and the same device, and having an edge between them.
In S206, the association is used as an edge of the network. The edge of the network generated by the association relationship may be a non-directional line segment edge or a directional edge.
In one embodiment, when an edge has a direction, the direction is pointed by an active user to a passive user. The active user is worthy of being the initiator of the call or the interaction, and the passive user refers to the receiver of the call or the interaction.
In S208, the registered user is regarded as a node of the network. Wherein, using the registered user as a node of the network comprises: determining attributes of the registered user; and determining attributes of the node based on the attributes; the attributes comprise positive attributes and negative attributes. Where each registered user is pre-assigned attributes, a positive attribute may, for example, represent that the user has good financial credit and a negative attribute represents that the user belongs to a frequently defaulting user. For example, the positive attribute represents that the user has a strong payment capability, the negative attribute represents that the user has a poor payment capability, and the like, which is not limited in the present application.
In S210, the at least one relational network is constructed based on the edges and the nodes.
In one embodiment, constructing the at least one relational network based on the edges and the nodes comprises: constructing a global network based on the edges and the nodes; determining similarity between nodes in the global network; and dividing the global network into at least one relational network based on the similarity between the nodes.
In one embodiment, the similarity may be calculated by, for example, the length of the call between each two users, or by sending a short message to each other, or by leaving the number of the contact to each other. The similarity between the online social network nodes describes the similarity between the online social network users, and according to different requirements and definitions, the similarity can be measured by using corresponding indexes, which specifically include the following indexes:
the Salton metric, also known as cosine similarity, is defined as the square root of the product of the ratio of the mutual neighbors of two nodes over their respective node degrees.
The Jaccard index is defined by the sum of the number of their neighbors over the ratio of the common neighbors of the two vertices.
The large node is a favorable index (HPI), and the number of common neighbors of two nodes is larger than the smaller node degree of the two nodes, so that the large node and other nodes are easier to have high similarity.
The high-degree node adverse index (HDI) is similar to HPI, and the denominator is obtained by taking the maximum value of the node degrees at both ends.
LHN-I index, the product of the ratio of the two vertex mutual neighbors to their degree.
The similarity between nodes may be determined by one or more of the metrics above.
In one embodiment, the similarity between nodes in the global network may be determined, for example, by hierarchical clustering. In the field of sociology, the similarity or distance between network nodes is generally defined by the topology of a given network, and then the network nodes are grouped into a tree-graph hierarchy by adopting single-connection hierarchical clustering or full-connection hierarchical clustering. Wherein leaf nodes of the tree represent network nodes, and non-leaf nodes are generally obtained by merging similar or closely spaced child nodes.
FIG. 3 is a schematic diagram illustrating a method for user financial risk assessment, according to another exemplary embodiment. As shown in FIG. 3, in one embodiment, the global network may be clustered by similarities between nodes, such that the global network is divided into a plurality of relational networks.
The global network may be partitioned to form at least one relational network by: and calculating the similarity between the nodes according to the number of incidence relations between every two nodes in the global network, and gradually reconnecting the nodes according to the sequence of the similarity from high to low. The method has the advantages that the division can be stopped at any time, and the method mainly comprises the following steps:
removing all edges in the network to obtain an initial state with n isolated nodes;
calculating the similarity of each pair of nodes in the network;
connecting corresponding node pairs from strong to weak according to the similarity to form a tree diagram;
and cutting the tree diagram according to the actual requirement to obtain a global network containing a plurality of relational networks.
According to the user financial risk assessment method disclosed by the invention, the global network formed by the users is divided into a plurality of relationship networks according to the association relationship between the users and the similarity between the users, so that the registered users with close relationship can be accurately and reasonably divided into one relationship network, and the user similarity in the relationship network is close, so that the relationship network can reflect the integrated characteristics of the users, and the financial risk classification judgment and the user characteristic description of the newly registered users in the later period are facilitated.
It should be clearly understood that this disclosure describes how to make and use particular examples, but the principles of this disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
FIG. 4 is a flow chart illustrating a method for user financial risk assessment according to another exemplary embodiment. The flowchart 40 shown in fig. 4 includes at least steps S402 to S408.
As shown in fig. 4, in S402, basic information of the current user is acquired. The basic information comprises contact persons and interactive record information; the interactive record information can be searched and determined on other communication network platforms by the mobile phone number in the contact of the current user.
In S404, the current user is compared with at least one registered user in at least one relationship network for similarity based on the basic information. For example, a random screening method may be adopted, in which one relationship network is determined from a plurality of relationship networks, and then a registered user is randomly determined from the relationship network for similarity comparison.
For example, the relationship networks having common characteristics with the user may be determined by performing a preliminary screening among the plurality of relationship networks according to other basic information of the user, such as the geographic location of the user, the gender or work information of the user, and the like, so as to perform a subsequent similarity comparison.
For example, the target user may be randomly determined among the registered users for similarity comparison, and a plurality of registered users may be preliminarily screened according to other basic information of the current user, such as the geographic location of the user, the gender or work information of the user, and the like, to determine registered users having common characteristics with the user for subsequent similarity comparison.
In S406, a target relationship network is determined from the at least one relationship network according to the comparison result.
In one embodiment, determining the target relationship network from the at least one relationship network according to the comparison result comprises: determining a target registered user from the at least one registered user according to the comparison result; and determining the relationship network to which the target registered user belongs as the target relationship network.
After the similarity comparison is performed for a plurality of times, the target registered user may be determined, for example, based on the comparison hijacking, and more specifically, a similarity threshold may be determined, for example, and when the similarity between the current user and the registered user is less than the threshold, the target registered user is determined. For example, the threshold of the comparison times may be determined, and for example, the threshold may be 100 times, after the current user is compared with 100 registered users, the similarity comparison is stopped, and then the comparison results of the 100 times of similarities are sequentially sorted from large to small, and the registered user with the largest similarity is taken as the target registered user.
In S408, the financial risk assessment of the current user is performed according to the characteristic attribute of the target relationship network.
