It should be understood that the specific embodiments described herein are intended to be illustrative only and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

The current socio-economic flow speed is high, so that the current transaction data volume is large, some abnormal transactions may exist in a large amount of transaction data, and in order to prevent the abnormal transactions from damaging social security, the transaction data needs to be screened from the large amount of transaction data. The current screening of transaction messages carrying transaction data has the following disadvantages:

(1) when the current transaction message is screened, a mode of screening all transaction messages is mainly adopted, and the screening workload is large due to the fact that the data volume of the current transaction message is large.

(2) The current screening strategy for transaction messages is a pre-solidified screening strategy, and the screening strategy needs to be changed when a supervision requirement is changed or a local supervision requirement is not applicable.

In order to solve the prior art problems, embodiments of the present application provide a message processing method, apparatus, device, and computer storage medium.

First, a message processing method provided in the embodiment of the present application is described below.

Fig. 1 shows a flowchart of a message processing method according to an embodiment of the present application. As shown in fig. 1, the method may include the steps of:

s110, acquiring a transaction message sent by a user;

s120, determining a message screening element corresponding to a user from a pre-configured message screening strategy; the message screening strategy comprises message screening elements corresponding to different users and message element content screening rules; the message screening strategy is a user message screening strategy generated by responding to the message screening strategy configuration operation of the user;

s130, extracting element contents corresponding to the message screening elements from the transaction message;

s140, screening and matching the element content according to the message element content screening rule corresponding to the user to obtain a message screening result.

Therefore, the message processing method in the embodiment of the application firstly obtains the transaction message sent by the user, then obtains the message screening element and the message element content screening rule corresponding to the user from the message screening strategy configured by the user, then extracts the element content corresponding to the message screening element from the transaction message, and then screens and matches the element content based on the message element content screening rule to obtain the message screening result. The message screening strategy is obtained based on the configuration of the user, so that the problem that the fixed screening strategy cannot meet the screening requirement can be avoided, and the message screening elements are extracted in the transaction message at first and then the extracted element content is screened, so that the problems of large workload and low screening efficiency caused by screening all transaction messages are avoided, and the screening efficiency is improved on the whole.

In some embodiments, in S110, the transaction message may include different formats and different types of messages carrying transaction data.

In some embodiments, in S120, the message screening policy is configured by the user, and the message screening policy may include a message screening element, a message element content screening rule, and a screening message type.

In some specific examples, the message screening element may include tags to be screened in the message, where each tag corresponds to a large amount of data. The message element content screening rule is used for memorability screening of a large amount of data corresponding to each label.

Therefore, the message screening strategy generated based on the configuration of the user can avoid the problem that the pre-generated message screening strategy cannot meet the local supervision requirement of the user. The generated message screening strategy has high applicability.

In some embodiments, the message screening policy further includes a screening message type, and S130 may specifically include:

In some embodiments, extracting a target message type corresponding to the screening message type from the transaction message may include:

after the target message type is determined, message screening elements corresponding to the current target message type and corresponding to different target message types are determined, and then element contents with high matching degree with the message screening elements are determined in the target message type.

Therefore, the target message type corresponding to the screening message type is extracted from the transaction message, the element content corresponding to the message screening element is extracted from the extracted target message type, and the element content is screened, so that the finally screened data volume is small, and the problem of low screening efficiency caused by large screened data volume due to screening of all transaction messages is solved.

In some embodiments, the message screening policy may include reference element content of the screening element. S140 may specifically include:

In some implementations, the matching results can include a similarity. Matching the element content with the corresponding reference element content may comprise:

the similarity between different fields in the element content and the reference element content is obtained.

In some embodiments, when the matching result indicates that the first element content in the element content matches with the corresponding reference element content, determining that the first element content is the abnormal transaction message element content may specifically include:

after the similarity between different fields in the element content and the reference element content is obtained, the similarity corresponding to the different fields may be compared based on a preset threshold, and a field corresponding to the similarity with the similarity greater than the preset threshold may be determined as the first element content matching the reference element content, that is, the abnormal transaction message element content.

In some embodiments, generating the message screening result according to the content of the abnormal transaction message element may specifically include:

and carrying out data cleaning on the acquired transaction message element content, and then generating a message screening result on the cleaned abnormal transaction message element content.

In some embodiments, the data cleaning of the acquired transaction message element content may specifically include: and carrying out duplication removal, combination and sequencing on the element contents of the transaction messages.

In some embodiments, after generating the message screening alarm information of the transaction message, the message processing method may further include:

and sending message screening alarm information to the user.

In some embodiments, after the message screening warning information is sent to the user, the user may recheck the message screening warning information based on the message screening warning information.

Therefore, the message screening alarm information is sent to the user, so that the user can timely process the message screening alarm information based on the message screening alarm information, and the timeliness of the user for processing the message alarm information is improved.

In order to avoid the technical problem that the message screening policy cannot be applied due to the change of the supervision requirement, the embodiment of the present application further provides a flow diagram of another message processing method. As shown in fig. 2, the method may further include the steps of:

and S210, responding to the updating operation of the message screening strategy of the user, and updating the message screening strategy of the user.

In some embodiments, the message screening policies corresponding to different users are different, and after a transaction message sent by a user is received, the message screening policy corresponding to the user may be determined based on the transaction message sent by the user.

In some specific examples, the latest supervision requirement may be obtained in time, and after the latest supervision requirement is obtained, the latest supervision requirement may be sent to the user, so that the user updates the message screening policy in response to the current supervision requirement.

Therefore, the message screening strategy is updated, and then the message is screened by the updated message screening strategy, so that the problem that the message screening strategy of the laggard version cannot meet the current screening requirement is solved.
