Fig. 1 is a flowchart of a risk prevention and control method provided in an embodiment of the present specification, where the method of fig. 1 may be executed by a terminal device. As shown in fig. 1, the method may include:

and step 110, processing the logistics address information for real-time transaction of the user to obtain a plurality of address elements.

The method comprises the following steps of processing logistics address information of a user for real-time transaction to obtain a plurality of address elements, and specifically comprises the following steps:

splitting logistics address information of a user for real-time transaction to obtain a plurality of address elements; or, the logistics address information of the real-time transaction of the user is recombined to obtain a plurality of address elements.

And step 120, determining the text similarity between the address elements in the temporary list and the preset address elements in the preset list.

The temporary list is created from a plurality of address elements, the temporary list being used to mark the plurality of address elements.

The preset address element may refer to each component in the correct logistics address.

The preset list is created from lock preset address elements.

In this embodiment of the present specification, determining a text similarity between an address element in the temporary list and a preset address element in the preset list may be implemented in the following manners:

firstly, determining the text similarity between the address elements in the temporary list and the preset address elements in the preset list through a text editing distance algorithm;

secondly, determining the text similarity between the address elements in the temporary list and the preset address elements in the preset list through an included angle cosine algorithm;

thirdly, determining the text similarity between the address elements in the temporary list and the preset address elements in the preset list through an Euclidean distance algorithm.

Step 130, determining whether to execute the transaction based on the text similarity of the address elements.

The determining whether to execute the transaction based on the text similarity of the address elements may specifically be: if the text similarity value of the address element is larger than the threshold value, terminating the execution of the transaction; and if the text similarity value of the address element is less than or equal to the threshold value, continuing to execute the transaction.

Optionally, as an embodiment, the step 120 may be specifically implemented as:

and determining the text similarity between the address elements in the temporary list and the preset address elements in the preset list based on the minimum number of editing operations required for converting the character strings corresponding to the address elements into the character strings corresponding to the preset address elements.

Illustratively, taking the address element as Cohinnd and the preset address element as China as an example:

the edit distance of Cohinnd and China needs to be calculated as Cohinnd → Cohinna → China

First, 7X 9 Table 1(Cohinnd length 7, China length 5, each plus 2) is created

TABLE 1

C

h

i

n

a

C

o

h

i

n

a

Then, the following positions are filled with numbers, as shown in table 2:

TABLE 2

		C	h	i	n	a
								0	1	2	3	4	5
C	1
							o	2
h	3
							i	4
n	5
							n	6
a	7

Starting from 3, 3 grids, the calculation is started. Take the minimum of the following three values:

the upper left digit if the uppermost character is equal to the leftmost character. Otherwise, it is the upper left digit + 1. (1 for 3, 3)

Left digit +1 (for 3, 3 grids 2)

Upper number +1 (for 3, 3 grids 2)

Thus, grid 3, 3 is 0, as shown in table 3:

TABLE 3

		C	h	i	n	a
								0	1	2	3	4	5
C	1	0
							o	2
h	3
							i	4
n	5
							n	6
a	7

The calculation starts with a 3, 4 (three rows and four columns) grid. Take the minimum of the following three values:

the upper left digit if the uppermost character is equal to the leftmost character. Otherwise, it is the upper left digit + 1. (2 for 3, 4)

Left digit +1 (for 3, 4 grids 1)

Upper number +1 (for 3, 4 grids 3)

Thus, panels 3, 4 are 1, as shown in table 4:

TABLE 4

		C	h	i	n	a
								0	1	2	3	4	5
C	1	0	1
							o	2
h	3
							i	4
n	5
							n	6
a	7

The operation was cycled to give Table 5

TABLE 5

		C	h	i	n	a
								0	1	2	3	4	5
C	1	0	1	2	3	4
							o	2	1	1	2	3	4
h	3	2	1	2	3	4
							i	4	3	2	1	2	3
n	5	4	3	2	1	2
							n	6	5	4	3	2	2
a	7	6	5	4	3	2

The lower right corner is taken to obtain an edit distance of 2.

In the embodiment of the description, based on the minimum number of editing operations required for converting the character string corresponding to the address element into the character string corresponding to the preset address element, the text similarity between the address element in the temporary list and the preset address element in the preset list is determined, and the modification of the address element can be dynamically captured, so that the wind control effect is better achieved.

Optionally, as an embodiment, the step 120 may be specifically implemented as:

respectively establishing vectors corresponding to the address elements and the preset address elements on the basis of the address elements in the temporary list and the preset address elements in the preset list;

and determining the text similarity between the address elements in the temporary list and the preset address elements in the preset list based on the cosine values of the vectors corresponding to the address elements and the preset address elements.

For example, for a two-dimensional space, assuming that the vectors corresponding to the address elements and the preset address elements are a and b, respectively, it is obvious that:

let the coordinates of the vectors a, b be (x), respectively₁，y₁)、(x₂，y₂). Then:

the cosine value ranges between [ -1,1], the closer the value is to 1, the closer the directions of the two vectors are, namely, the more similar the address element is to the preset address element, the smaller the similarity value is; the closer to-1, the more opposite their direction, i.e. the more different the address element and the preset address element, the greater the similarity value.

The embodiment of the description establishes vectors corresponding to the address elements and the preset address elements respectively based on the address elements in the temporary list and the preset address elements in the preset list; and determining the text similarity between the address elements in the temporary list and the preset address elements in the preset list based on the cosine values of the vectors corresponding to the address elements and the preset address elements, and dynamically capturing the modification of the address elements so as to better achieve the wind control effect.

Optionally, as an embodiment, the step 110 may be specifically implemented as:

and splitting the logistics address information of the user for real-time transaction by taking the separators as splitting nodes to obtain a plurality of address elements.

The separator may be a common separator, which may be a space, an underline, a comma, a semicolon. Illustratively, delimiters (“ - ”, “ _ ”, “, ”, “ ”) are commonly used.

Exemplarily, assuming that the logistics address is China Beijing chaoyangqu, the separator is used as a splitting node, and after splitting the logistics address information of the user for real-time transaction, a plurality of address elements are respectively China, Beijing and chaoyangqu.

The embodiment of the specification takes the separator as the splitting node, splits the logistics address information of the real-time transaction of the user, so as to simply split the logistics address information to obtain each element of the logistics address, so that the text similarity of each element can be conveniently determined in the follow-up process, fuzzy modification of each element can be captured in real time without any adjustment, and a foundation is laid for achieving a better wind control effect.

Optionally, as an embodiment, before performing step 110, the risk prevention and control method provided in this embodiment may further include:

before the plurality of address elements are obtained by processing the logistics address information for real-time transaction of the user, the method further comprises the following steps:

acquiring transaction data of a user for real-time transaction;

if the transaction data meet risk conditions, determining that the transaction corresponding to the transaction data is a risk transaction; the risk condition is a condition with the action of embezzlement of transaction information;

step 110 may be specifically implemented as:

and processing the logistics address information based on the risk transaction to obtain a plurality of address elements.

In the embodiment of the description, transaction data of real-time transactions of users are screened, risky transactions (namely risk transactions) are screened, and logistics address information based on the risk transactions is processed to obtain a plurality of address elements, so that the transaction data of the real-time transactions are preliminarily screened, the data volume is reduced, the occupied space of a memory is reduced, and the efficiency is improved.

Optionally, as an embodiment, the step 130 may be specifically implemented as:

if the obtained maximum text similarity value is larger than a threshold value, terminating the execution of the transaction;

and if the obtained maximum text similarity value is less than or equal to the threshold value, continuing to execute the transaction.

In the embodiment of the description, the maximum text similarity value is selected from the plurality of address elements, and if the maximum text similarity value is greater than a threshold value, the transaction is terminated; if the maximum text similarity value is larger than the threshold value, the transaction is stopped, fuzzy modification of the address elements can be captured dynamically, whether the transaction is executed or not can be judged in real time according to the fuzzy modification of the address elements, the safety is improved, and a better wind control effect can be achieved.

The method of the embodiments of the present invention will be further described with reference to specific embodiments.

at 250, the text similarity between the address elements in the temporary list and the preset address elements in the preset list is determined based on the minimum number of editing operations required for converting the character strings corresponding to the address elements into the character strings corresponding to the preset address elements.

At 260, the maximum text similarity value is taken for the calculated text similarity values of all address elements;

at 270, the retrieved maximum text similarity value is compared to a threshold to determine whether the maximum text similarity value is greater than the threshold;

at 280, if the obtained maximum text similarity value is greater than a threshold value, terminating execution of the transaction;
