Embodiment Construction

[0050] The solutions provided in this specification will be described below in conjunction with the accompanying drawings.

[0051] figure 1 It is 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 fund products, for example, fund product 1, fund product 2, ..., fund product 10, each fund 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 various fund products mentioned above may include products within the electronic payment system, such as consumer credit products, loan service products, electronic wallet products, currency fund products, bank products, etc. Generally, for consumer credit products, each...

Abstract

The embodiment of the invention provides a user intention mining method and device based on user transaction data, and the method comprises the steps: obtaining a pre-constructed time sequence transaction graph which is constructed based on the user transaction data of each user, and comprises nodes and connection edges, a single node corresponds to a single fund container of a single user, and each connection edge corresponds to one transaction; a user intention sub-graph corresponding to a specific user intention is obtained, the user intention sub-graph has a set target graph structure, and each node in the target graph structure has a set fund container type; matching the user intention sub-graph with the time sequence transaction graph to obtain a first transaction sub-graph included in the time sequence transaction graph, the first transaction sub-graph having the target graph structure; and according to the specific user intention, determining a user intention of a target user involved in the first transaction sub-graph. And the requirements of efficiency and accuracy can be met.

Description

technical field [0001] One or more embodiments of this specification relate to the computer field, and in particular to a method and device for mining user intentions based on user transaction data. Background technique [0002] Hundreds of billions of transactions occur in the electronic payment system every day, and these transactions link complex transaction relationship networks among people, merchants, institutions, etc. Each transaction will involve the user's capital flow, and the key information in the transaction can be called user transaction data, for example, the users involved in the transaction, the financial products involved in the transaction, the amount information of the transaction, etc., by analyzing the user transaction data, you can Unearth the intent behind a series of transactions performed by users. Through the mining of user intentions, corresponding applications such as capital route optimization, capital product optimization, capital risk and se...
