Example Embodiment

[0048] Example one

[0049] In one or more embodiments, a bank account transaction behavior image is disclosed, referring to figure 1 , Including the following process:

[0050] (1) Get account transaction information, extract the transaction stream synthetic relationship, and form a transaction summary information;

[0051] Specifically, build payment dedicated servers, which is specifically used for data storage, feedback, etc. of corporate bank account transaction water, special service, special operation and maintenance to ensure data security.

[0052] During the data acquisition, the front-end machine is set separately on the portrait build system and the monitored bank account system, and the channel security is guaranteed using the VPN, HTTPS Protocol (SSL) and the special line. The front-end machine is used to transmit the transaction information between the two systems and perform data encryption and decryption operations.

[0053] With the International Standard Encrypt...

Example Embodiment

[0087] Example 2

[0088] In one or more embodiments, a bank account trading behavior portrait building system, including:

[0089] The data acquisition module is used to obtain account transaction information, extract the transaction stream synthetic relationship, and form a transaction summary information;

[0090] Relationship build module, used to distinguish the extracted transaction summary information, the word, named entity identification, and dependent syntax analysis, and finally generate a syntax relational tree;

[0091] The label extraction module is used to extract the transaction label and business tag from the rules in the syntax relationship;

[0092] The account portrait module is used to use the accuracy and the recall rate to compute static and dynamic information, and the exception transaction content is summarized, and the account portrait is drawn.

[0093] During data acquisition, the front-end machine is provided on the portrait build system and the monito...

Example Embodiment

[0095] Example three

[0096] In one or more embodiments, a terminal device includes a server, the server comprising a memory, a processor, and a computer program stored on a memory and can run on a processor, the processor executing A method of implementing the bank account transaction behavior in the first embodiment is a program. For the sake of brevity, will not be described here.

Abstract

The invention discloses a bank account transaction behavior portrait construction method and system, and the method comprises the steps of obtaining account transaction information, extracting a transaction flow syntactic relation, and forming transaction summary information; performing word segmentation, part-of-speech tagging, named entity recognition and dependency syntactic analysis on the extracted transaction summary information, and finally generating a syntactic relation tree; extracting a transaction label and a service label from the syntactic relation tree according to a rule; and performing comprehensive calculation on the static and dynamic information by using the accuracy rate and the recall rate, performing summary statistics on abnormal transaction contents, and drawing an account portrait. According to the invention, label definition is carried out on transaction behaviors of the enterprise bank account, syntactic relation analysis is carried out on information such as abstracts, transaction time, collection and payment, account abnormal actions are insighted in time, transaction risks are accurately positioned, and a high-precision risk prevention and control means is provided for comprehensive monitoring and safe use of the enterprise fund transaction account.

Description

technical field [0001] The invention relates to the technical field of bank account portraits, in particular to a method and system for constructing bank account transaction behavior portraits. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The corporate bank account is the carrier of the company's capital operation. The account flow directly reflects the transaction behavior of the account. By extracting the company's massive bank fund transaction flow, it analyzes the syntactic relationship of the summary, transaction time, collection, payment and other information, and intelligently connects transactions. Tags and business tags to build a dynamic, complete and comprehensive capital account transaction portrait, which can help companies understand the historical transaction behavior of the account in real time, grasp the account transac...
