Embodiment Construction

[0050] The solution provided in this specification will be described below with reference to the accompanying drawings.

[0051] figure 1 A schematic diagram of an implementation scenario of an embodiment disclosed in this specification. This implementation scenario involves mining user intent based on user transaction data. refer to figure 1, after the user opens account 1 in the electronic payment system, the account 1 is associated with various capital products, for example, capital product 1, capital product 2, ..., capital product 10, each capital product can also be associated with multiple sub-products, For example, capital product 4 is associated with sub-product 1, sub-product 2, ..., sub-product 5. The above-mentioned various capital products may include products within the electronic payment system, such as consumer credit products, loan service products, electronic wallet products, monetary fund products, bank products, and the like. Generally, for consumer cre...

Abstract

Embodiments of this specification provide a method and device for mining user intentions based on user transaction data. The method includes: acquiring a pre-built time-series transaction diagram, the time-series transaction diagram being constructed based on user transaction data of each user, and the time-series transaction diagram Including nodes and connecting edges, a single node corresponds to a single fund container of a single user, and each connecting edge corresponds to a transaction; obtain a user intent subgraph corresponding to a specific user intent, and the user intent subgraph has a set target graph structure , each node in the target graph structure has a set fund container type; match the user intent subgraph with the sequence transaction graph to obtain the first transaction subgraph included in the sequence transaction graph, and the first transaction subgraph included in the sequence transaction graph is obtained. A transaction subgraph has the target graph structure; according to the specific user intent, the user intent of the target user involved in the first transaction subgraph is determined. It can meet the requirements of efficiency and accuracy.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computers, and in particular, to a method and apparatus for mining user intentions based on user transaction data. Background technique [0002] There are hundreds of billions of transactions in electronic payment systems every day, and these transactions are linked to a complex network of transaction relationships between people, merchants, and institutions. Each transaction involves the user's capital flow, and the key information in the transaction can be called user transaction data, such as the users involved in the transaction, the financial products involved in the transaction, and the amount information of the transaction. By analyzing the user transaction data, you can Uncover the intent behind a series of transactions made by users. Through the user intentions excavated, the corresponding capital path optimization, capital product optimization, capital risk and security gua...
