Detailed Description
The core of the application is to provide a behavior evaluation method, which can rapidly and accurately excavate the whole association group according to the related information of enterprises with known behavior types, thereby realizing the effective evaluation and unified management of the whole group; another core of the present application is to provide a behavior assessment apparatus, a device and a computer-readable storage medium, which also have the above-mentioned advantages.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a behavior evaluation method provided in the present application, where the behavior evaluation method may include:
s101: acquiring target data information of a target enterprise; wherein the target enterprise is an enterprise with a known behavior type;
specifically, the identification and evaluation of the enterprise associated group with a specific behavior type mainly depends on a certain enterprise determined to have the specific behavior, and further data mining and searching are performed on the basis of the enterprise, so that the corresponding enterprise associated group can be obtained, and therefore group management and supervision are achieved. Therefore, when identifying and evaluating an enterprise-related group having a certain specific behavior, it is first necessary to acquire related data of an enterprise for which the specific behavior is determined to exist, that is, the target enterprise, and of course, the related data is data having a certain association relationship with the specific behavior, that is, the target data information. The type of the target data information corresponds to the behavior type of the target enterprise, for example, for an enterprise with tax evasion behavior, the target data information is the tax payment information of the enterprise, and for an enterprise with false invoice behavior, the target data information is the invoice information of the enterprise. The above method for acquiring the target data information may be implemented based on any one of the existing technologies, which is not limited in this application.
S102: extracting information of the target data information to obtain initial associated enterprise information and initial associated personnel information;
the step aims to extract information of the target data information when the target data information is obtained so as to obtain information of other enterprises and persons having a certain incidence relation with the target enterprise, namely the initial associated enterprise information and the initial associated person information. For example, when a target enterprise has a false invoice issuing behavior, the invoice information is target data information, which includes information such as transaction data, information of supply and marketing parties, financial responsible persons, ticket purchasing persons, and the like, so that all relevant enterprises and persons suspected to participate in the false invoice issuing behavior of the target enterprise, including upstream relevant enterprises and persons, downstream relevant enterprises and persons of the target enterprise, can be extracted from the target data information; further, the enterprise and the personnel which have a relationship with the target enterprise virtual invoice making behavior to a certain extent can be extracted from all the related enterprises and personnel, so as to obtain the corresponding initial related enterprise information and initial related personnel information, for example, the related enterprises at the upstream layer and the downstream layer of the target enterprise can be extracted as the initial related enterprises, and the related personnel at the downstream layer of the target enterprise can be extracted as the initial related personnel.
S103: calculating the infection degree of the initial associated enterprise according to the initial associated enterprise information, and extracting intermediate associated enterprise information meeting a preset infection degree threshold condition from the initial associated enterprise information;
after the initial associated enterprise information is obtained, the infection degree calculation is carried out on the corresponding initial associated enterprises based on the initial associated enterprise information, so that intermediate associated enterprises with higher association degree with target enterprises are extracted from all the initial associated enterprises, and corresponding related information, namely the intermediate associated enterprise information, is obtained; wherein the intermediate associated enterprise has a higher degree of association with the target enterprise than the initial associated enterprise. Specifically, the higher the infection degree is, the higher the association degree between the initial associated enterprise and the target enterprise is, so that the infection degrees of all the initial associated enterprises compared with the target enterprise can be calculated, and the initial associated enterprise with the infection degree higher than the preset infection degree threshold value is extracted as the intermediate associated enterprise, thereby further obtaining the corresponding intermediate associated enterprise information. Of course, the specific value of the preset infection threshold may be set by a technician according to actual needs, which is not limited in this application.
S104: performing intimacy calculation on the initial associated personnel according to the initial associated personnel information, and extracting intermediate associated personnel information meeting a preset intimacy threshold value condition from the initial associated personnel information;
after the initial associated person information is obtained, performing affinity calculation on corresponding initial associated persons based on the initial person information, so as to extract and obtain intermediate associated persons with higher association degree with the target enterprise from all the initial associated persons, and obtain corresponding related information, namely the intermediate associated person information; wherein the degree of association between the intermediate associated person and the target business is higher than the initial associated person. Specifically, the higher the intimacy degree is, the higher the degree of association between the initial associated person and the target enterprise is, so that the intimacy degree of all the initial associated persons compared with the target enterprise can be calculated, and the initial associated person with the intimacy degree higher than a preset intimacy degree threshold value is extracted as the intermediate associated person, so that the corresponding intermediate associated person information is further obtained. Similarly, the specific value of the preset intimacy degree threshold value may be set by a technician according to actual needs, which is not limited in the present application.
It should be noted that, S103 and S104 respectively implement the infection degree calculation for the initial related enterprise and the intimacy calculation for the initial related personnel, but the implementation order of the above two steps does not affect the implementation of the present technical solution, and certainly, to ensure the evaluation efficiency, the two steps can be executed simultaneously.
S105: constructing a correlation network big graph according to the intermediate correlation enterprise information and the intermediate correlation personnel information;
specifically, the step aims to construct an association network large graph with a higher association degree with the target enterprise based on the intermediate association enterprise information and the intermediate association personnel information, so that other enterprises or personnel with higher similarity to the target enterprise behavior type can be obtained according to more accurate identification of the association network large graph in the subsequent process, and the identification of the enterprise association group is completed. The relational network large graph can clearly represent the relation information among the target enterprise, the intermediate relational enterprise and the intermediate relational personnel, and the identification and evaluation of the enterprise relational group are more convenient. Of course, any one of the prior arts can be adopted for the method for constructing the associated network large graph, and the application is not limited.
S106: screening the association degree of the association network large graph to obtain association enterprises and association personnel;
s107: and marking the associated enterprises and the associated personnel as behavior types corresponding to the target enterprises.
Specifically, the steps are to further screen the associated network large graph to accurately obtain the associated enterprises and associated persons of the same behavior type as the target enterprise, that is, the associated enterprises are other identified enterprises participating in the specific behavior of the target enterprise, and the associated persons are identified related persons participating in the specific behavior of the target enterprise; further, the two can be marked as the corresponding behavior types of the target enterprises, thereby completing the identification and evaluation of the enterprise association groups with a certain specific behavior. In addition, the screening mode of the association degree can be realized based on a relevant algorithm or a business rule.
As a preferred embodiment, please refer to fig. 2, fig. 2 is a schematic flowchart of a network large graph screening method in a behavior evaluation process provided by the present application, where the screening of the association degree of the associated network large graph to obtain the associated enterprise and the associated personnel may include:
s201: calculating a big associated network graph by using a connected community division algorithm to obtain a connected subgraph set;
s202: screening all connected subgraphs in the connected subgraph set through a preset service rule to obtain associated subgraphs;
s203: and extracting the associated enterprises and the associated persons from the associated subgraph.
The application provides a more specific associated subgraph screening method, which comprises the steps of firstly carrying out calculation processing on an associated network big graph through a connected community division algorithm to obtain a connected subgraph set, wherein the connected subgraph set comprises a plurality of connected subgraphs with a certain association relation, the connected community division algorithm is an algorithm which is provided for reasonably dividing a complex network and finding out a real existing community structure, and the algorithm has higher division accuracy. Further, all connected subgraphs in the connected subgraph set can be filtered based on preset business rules, so that associated subgraphs are obtained, all enterprises and persons involved in the associated subgraphs correspond to the associated enterprises and the associated persons, and therefore the associated enterprises and the associated persons can be extracted and obtained from the associated subgraphs. Of course, the preset business rules can be set differently according to actual requirements, and mainly aim at the number of enterprise nodes and the degree of output of personnel nodes in the associated subgraph.
As a preferred embodiment, the behavior evaluation method may further include performing service verification on the associated subgraph to obtain a verification result; and determining a group operation mode according to a verification result by combining the preset connectivity mode.
Specifically, the embodiment aims to verify the identification result, that is, the associated subgraph, so as to obtain a corresponding verification result, and further, determines the group operation mode of the identified enterprise associated group in combination with a preset connectivity mode, so as to facilitate subsequent auditing work of relevant departments. The group operation mode can be divided into a transaction control triangle, a quadrilateral ring, a pentagonal ring and the like, the preset communication relation mode is the same as the above, and the specific type of the preset communication relation mode can be set according to actual business requirements.
The transaction control triangle is composed of a transaction relation side and two control relation sides; rings larger than the triangle may be closed rings of groups (such as fund flow), or closed rings of enterprises (such as transactions between a same enterprise and different related enterprises), and the relationship information in such rings is complex, and cannot be directly identified as a group partner, and further pattern recognition (such as occupation ratio of the number of people in the rings and the transaction relationship control relationship) needs to be performed depending on business rules. Furthermore, for the case where two persons control multiple same businesses (including more than 2 businesses with specific behaviors), the two persons may be considered to be one person (e.g., family relatives), and for such cases, the triangular ring of money return may be expanded to a quadrilateral, pentagonal ring, etc.
According to the behavior evaluation method provided by the application, according to the related data information of the target enterprise with the specific behavior type, the infectivity and the affinity of all related enterprises and persons are calculated, so that the construction of the associated network big graph is completed, further, the associated network big graph is subjected to association degree screening, and other enterprises and persons with the same behavior type as the target enterprise can be identified and obtained from the associated network big graph, so that the enterprises and persons with the same association can be mined out based on the enterprise with the specific behavior type of one user, the identification of the group with the same behavior type is realized, the effective evaluation and unified management of the group by professional departments are facilitated, and the real-time performance and the pertinence are higher; in addition, the enterprise behavior evaluation is realized based on the computer technology, and compared with the method for carrying out classification evaluation on individuals through manual investigation in the prior art, the method has higher evaluation efficiency and evaluation accuracy.
On the basis of the above embodiments, please refer to fig. 3, and fig. 3 is a schematic flow chart of a method for extracting relevant information in a behavior evaluation process according to the present application.
As a preferred embodiment, the process of extracting information from the target data information in S102 to obtain the initial associated enterprise information and the initial associated person information may specifically include:
s301: acquiring all related enterprise information and all related personnel information according to the target data information;
s302: integrating all related enterprise information and related personnel information to generate a two-dimensional wide table;
s303: importing the two-dimensional wide table into an ArangoDB graph database for processing to obtain an initial association network;
s304: and extracting initial associated enterprise information and initial associated personnel information in a preset range of the initial associated network.
The method for extracting the initial associated enterprise and the initial associated personnel is a more specific implementation mode. Specifically, all other enterprises and persons having an association relationship with the target enterprise, that is, all enterprises and persons involved in the target data information, may be extracted from the target data information, and then integrated to generate a two-dimensional wide table, so that the two-dimensional wide table covers all other enterprises and persons related to the target enterprise and their corresponding relationships; further, the two-dimensional broad table is imported into an ArangoDB graph database for processing, the ArangoDB supports a flexible data model and has high performance, the two-dimensional broad table is processed by the ArangoDB to obtain a corresponding initial association network, the initial association network is similar to the association network large graph, but the difference is that the relationship information among a target enterprise, an initial association enterprise and initial association personnel is clearly represented in the initial association network, and the relationship information among the target enterprise, intermediate association enterprises and intermediate association personnel is clearly represented in the association network large graph. Therefore, the initial associated enterprise and the initial associated personnel can be extracted within the preset range in the initial associated network. Of course, the setting of the preset range does not affect the implementation of the present technical solution, and referring to the example of the previous embodiment, the preset range may be related enterprises and people in the upstream layer and the downstream layer from the target enterprise.
Preferably, the integrating all the related enterprise information and the related personnel information to generate the two-dimensional wide table may include: constructing a triple transaction edge of the target enterprise-relation-related enterprise according to all related enterprise information; constructing a first triple control edge of the related personnel-relationship-target enterprise according to all related personnel information; constructing a second triple control edge of the related personnel-relationship-related enterprise according to the triple transaction edge and the first triple control edge; and integrating the triple transaction edge, the first triple control edge and the second triple control edge to obtain the two-dimensional width table.
For the acquisition process of the two-dimensional wide table in S302, the present application provides a more specific implementation manner. Specifically, the triple transaction edge of the target enterprise-relation-related enterprise and the triple control edge of the related personnel-relation-target enterprise can be constructed based on all related enterprise information and related personnel information, and the triple control edge of the related personnel-relation-related enterprise is further obtained according to the triple transaction edge and the related personnel-relation-related enterprise, so that the corresponding two-dimensional broad table can be obtained based on the integration of the triple transaction edge and the two triple control edges.
Preferably, the extracting the initial associated enterprise information and the initial associated person information within the preset range of the initial associated network may include extracting the initial associated enterprise information and the initial associated person information within the preset range of the initial associated network by using a breadth-first search algorithm.
Specifically, the method for extracting the initial associated enterprise information and the initial associated person information in S303 may be implemented based on a Breadth-First Search algorithm (BFS), where the BFS algorithm is a graph Search algorithm, and all nodes in a graph may be systematically expanded and checked to find a result, and the BFS algorithm has completeness, that is, regardless of the type of a graph, as long as a target exists, a target node, that is, an enterprise and a person with fraudulent behavior may be found.
Therefore, based on the process, the extraction of the initial associated enterprise information and the initial associated personnel information is realized, and the identification efficiency and the identification accuracy are higher.
On the basis of the foregoing embodiments, to further improve the recognition accuracy, the behavior evaluation method may further include: feeding back and adjusting parameters according to the verification result; the adjusting parameters comprise a preset infection threshold, a preset intimacy threshold, a preset range of an initial association network, a preset service rule and a preset communication relation mode.
The embodiment of the application aims to realize feedback adjustment of related parameters so as to further improve the accuracy of the identification algorithm. Specifically, the verification of the relevant parameters, that is, the preset parameters involved in the behavior evaluation process, may be implemented according to the verification result, and specifically may include a preset infection threshold, a preset intimacy threshold, a preset range of the initial association network, a preset business rule, a preset connectivity mode, and the like.
For other implementation steps in the embodiments of the present application, reference may be made to the previous embodiment, and details of the present application are not described herein again.
The behavior evaluation method provided by the embodiment of the application effectively realizes the adjustment of each preset relevant parameter in the identification process based on the identification result, improves the accuracy of the behavior identification algorithm, and further improves the accuracy of the corresponding evaluation result.
On the basis of the above embodiments, taking a target enterprise with a false invoice issuing behavior as an example, the application provides a more specific behavior evaluation method. The virtual enterprise in the following contents is the target enterprise.
(1) Processing original data (namely the target data information) of the invoice virtual-open enterprise, integrating and extracting data information including the virtual-open enterprise, the virtual-open invoice associated enterprise and personnel thereof, and acquiring related total data (namely the initial related enterprise information and the initial related personnel information):
the invoice virtual-open enterprise is a target enterprise which is identified and determined to have the invoice virtual-open behavior, and the original data of the invoice virtual-open enterprise is further input as an invoice virtual-open group identification algorithm for data processing.
In the embodiment, the pseudo-open enterprise is taken as a starting point, one layer is found at the upstream of the pseudo-open enterprise, three layers are found at the downstream, and all the obtained data of the related enterprises form triple transaction edges of the pseudo-open enterprise-relation-related enterprises.
The data information of the associated personnel can be obtained from data such as tax register data of taxpayers, investment relation data, natural person information and the like so as to obtain basic information, such as identity numbers, mobile phone numbers, attributions and the like of personnel associated with the invoice virtual opening enterprise, such as enterprise legal persons, investors, financial responsible persons, tax clerks, ticket buyers and the like, and therefore all the obtained associated personnel data form a triple control edge of the associated personnel-relation-virtual opening enterprise.
Further, according to the triple transaction edge and the triple control edge in the two steps, association between the associated personnel and the associated enterprise is carried out, and a triple control edge of the associated personnel-relationship-associated enterprise is formed. Therefore, the triple transaction side data and the two triple control side data can be integrated, and the entity data in the triple transaction side data and the two triple control side data are extracted to form a two-dimensional wide table.
Further, the two-dimensional broad table is imported into an ArangoDB database to form an initial association network of enterprises and personnel and enterprises. Specifically, firstly, integrating a triple transaction EDGE and a triple control EDGE into an EDGE EDGE table; secondly, extracting an enterprise in the triple transaction edge as an entity 1, extracting a person in the triple control edge as an entity 2 and an enterprise as an entity 3, and making an entity 1/2/3 into a node VERTEX point table; and finally, taking the EDGE EDGE table as the relation input and the VERTEX point table as the entity input to construct an initial association network of TH (group partner). Wherein, the relevant attributes of the VERTEX point table and the EDGE EDGE table can be set as follows:
VERTEX Point Table:
key: the enterprise node is the taxpayer electronic file number, and the personnel node is the identity card number;
sfxk: whether a false opening behavior exists, 1 is selected, and 0 is not selected; wherein, because the personnel are all related personnel of the virtual enterprise, the personnel nodes all take 1;
and (3) ishuman: distinguishing whether the nodes are personnel nodes or not, wherein the personnel nodes are 1, and the enterprise nodes are 0;
sensi _ weight: the infection degree is set to 0 in the initial value;
int _ weight: setting the initial values of the intimacy degree to be 0;
is _ community: whether the initial value is a virtual open group is set to be 0;
community _ label: the virtual open burst indicates that the initial values are all set to 0.
EDGE EDGE table:
from: the triple transaction side is the electronic document number of the seller taxpayer, and the triple control side is the identity card number of the responsible person;
a _ to: downstream enterprise taxpayer electronic file number;
je: supply and sale monthly information amount;
xfxkze: the total amount of the false invoices are made by the false-invoicing enterprises;
gfze: the total amount of the false invoice purchased by the buyer;
tradeFrom: the buyer obtains the amount of the false invoice/the seller issues the amount of the false invoice with 100%;
tradeTo: the buyer obtains the amount of the false invoice/the total purchase amount of the seller 100%;
control type: the personnel control the type of the enterprise, wherein 1 is a legal person, 2 is a financial person, 4 is a tax clerk, 8 is a ticket purchaser, 16 is an investor, and the combination of multiple functions is the addition of numbers.
Further, information required by algorithm construction is obtained from the initial association network, secondary integration is carried out, and a data format required by the algorithm is constructed. Specifically, in the initial association network, with the invoice virtual-open enterprise as a starting point, carrying out breadth-first traversal (BFS) on the graph to find out relationship data of an upstream layer and a downstream layer; and (4) with the personnel as a starting point, performing breadth-first traversal (BFS) of the graph to find the relationship data of a downstream layer, thereby completing the acquisition of the initial associated enterprise information and the initial associated personnel information.
(2) Infection degree calculation process:
specifically, all edges are traversed, and the infection degree of the downstream nodes is calculated for the edges meeting the conditions that the from is an invoice virtual-open enterprise and the to is a non-invoice virtual-open initial associated enterprise. Here, it should be noted that only the invoice utility and the downstream node have a utility transaction relationship, and the infection degree can be calculated. In addition, the infection degree is accumulated when a plurality of invoice virtual-open enterprises infect the same enterprise node.
Wherein, the infection degree calculation formula of the downstream non-invoice virtual-open enterprise is as follows:
sendiwight threshold + tradetto (1-threshold);
the threshold is a parameter threshold preset based on business logic, and is set to be 0.5 in the application; tradeFrom accounts for the amount of the false invoices obtained by the purchaser to the amount of the false invoices made by the seller, and tradeTo accounts for the amount of the false invoices made by the purchaser to the total amount purchased by the purchaser.
The mode of calculation of the infectivity is described by way of example below:
virtually opening an enterprise A:
{“sensi_weight”:1}；
the transaction relationship is as follows:
{“tradeFrom”:0.3,“tradeTo”:0.6}；
opening a downstream enterprise B:
{“sensiWeight”:？}
then the infectivity of B is: 0.3 × 0.5+0.6 × 0.5 ═ 0.45.
(3) And (3) calculating intimacy:
specifically, because the affinity is an attribute of the person node-associated enterprise, all the person nodes may be traversed first, and all the enterprise nodes downstream are traversed in the initial association network with the person nodes as a starting point, where a depth is set to 1, that is, the related information of the enterprise at the downstream layer is traversed. Wherein, the intimacy degree is updated for non-false-invoice enterprises in downstream enterprise nodes, and the cumulative intimacy degree associated with a plurality of invoice false-invoice enterprises for the same enterprise node is provided with personnel.
First, an affinity corresponding value is defined for the controlType attribute in the EDGE table as follows:
scores＝{‘1’:0.5,‘2’:0.2,‘4’:0.1,‘8’:0.1,‘16’:0.5,……}；
the intimacy calculation formula of the non-virtual open enterprises in the associated enterprises is as follows:
intiWeight＝scores[controlType0]+scores[controlType1]；
wherein, the controlType0 is the controlType between the personnel and the invoice virtual company, and the controlType1 is the controlType between the same personnel and the invoice virtual company.
The mode of calculation of the infectivity is described by way of example below:
a virtual enterprise A, a person M and a person downstream enterprise C; wherein the content of the first and second substances,
the control relation between M and A is as follows: if the person is both a legal person and a responsible person, then { "controlType": 17 };
the control relation between M and C is as follows: the person who acts as a legal person, then { "controlType": 1 };
then, staff downstream Business C { "intiWeight":? };
then 17:0.5+0.5 ═ 1; 1: 0.5; the intimacy of C is then: 1+0.5 ═ 1.5.
Further, node filtering is performed based on a preset infection threshold and a preset intimacy threshold, and in the application, the preset infection threshold is set to be 0.35, and the preset intimacy threshold is set to be 0.6. Therefore, the nodes with the infection degrees larger than 0.35 and the nodes with the intimacy larger than 0.6 can be extracted, and the intermediate associated enterprise information and the intermediate associated personnel information are obtained.
(4) Constructing a big associated network graph:
in the step, the purpose is to reconstruct an association network big graph which clearly represents the relationship information among the invoice virtual-open enterprises, the intermediate association enterprises and the intermediate association personnel according to the filtered nodes and edges.
(5) And identifying the invoice false-open party:
calculating the association network big graph by adopting a connected community division algorithm, and filtering once to obtain a connected subgraph set with the number of enterprise nodes being more than 3 and the degree of departure of personnel nodes being more than 2; and further traversing each connected subgraph meeting the preliminary conditions in the set again based on preset service rules, judging whether the connected subgraph meets a mode that a personnel control relationship is primary and a transaction relationship is secondary, obtaining the connected subgraphs with the number of enterprise nodes more than 3 and the output degree of the personnel nodes more than 2 by secondary filtering, and marking the enterprises and the personnel involved in the connected subgraphs as puzzles, thereby obtaining the associated subgraphs and realizing the invoice false-open and puzzles identification.
(6) Verifying the invoice virtual open group and analyzing the operation mode:
specifically, the invoice virtual-open gang is subjected to service verification according to actual service rules, so that common group operation modes such as a triangular loop and a quadrilateral loop are obtained, and therefore, pattern matching can be performed in an initial association network according to the modes, and a new qualified recognition result is obtained. Aiming at the invoice false invoice issuing behavior, the corresponding business rule can be that the false invoice issuing chain is not too long, so that the false invoice issuing needs to ensure fund backflow.
(7) And (3) feedback and parameter adjustment:
specifically, according to the verification result, algorithm feedback adjustment is performed, which mainly adjusts a preset infection threshold (values such as 0.1,0.3,0.6 and 0.9), a preset intimacy threshold (values such as 0.2,0.35,0.45 and 0.7), a node number K (values such as 3,4 and 7), a mode of a connected relationship (types such as triangle, quadrangle and pentagon) and the like.
