Problems solved by technology

[0003] However, the interaction event involves both parties, and the state of each participant can change dynamically. Therefore, it is very difficult to accurately express the characteristics of the interaction participants by comprehensively considering the various characteristics of the interaction participants.

Embodiment approach

[0142] According to an implementation manner, the nodes within the predetermined range include: nodes within connection edges of a preset order K; and / or nodes whose interaction time is within a preset time range.

[0143] In one embodiment, each interaction event may also include the event characteristics of the interaction event; in this case, the node characteristics of each node may include the attribute characteristics of the object corresponding to each node, and the interaction event where each node is located event characteristics.

[0144] According to an embodiment, the service processing unit 104 is configured to, according to the first feature vector, predict the classification category of the object corresponding to the first target node.

[0145] According to an implementation manner, the subgraph determining unit 102 is further configured to, in the dynamic interaction graph, determine a second target subgraph corresponding to a second target node, the second ta...

Abstract

The embodiments of this specification provide a method and device for processing interaction data. In this method, first obtain the dynamic interaction graph constructed according to the interaction event set, in which any node i points to the M associated nodes corresponding to the N associated events that the object represented by the node i participated in last time through the connection edge, where it is allowed Objects participate in multiple association events at the same time, allowing nodes to connect to more than 2 association nodes. Then, in the dynamic interaction graph, the target subgraph corresponding to the target node is determined, and the target subgraph includes nodes within a predetermined range that start from the target node and reach via connecting edges; then, based on each The node characteristics of the nodes and the pointing relationship of the connection edges between the nodes can determine the characteristic vector corresponding to the target node for business processing.

Description

technical field [0001] One or more embodiments of this specification relate to the field of machine learning, and in particular to a method and device for processing interaction sequence data using machine learning. Background technique [0002] In many scenarios, user interaction events need to be analyzed and processed. Interaction events are one of the basic elements of Internet events. For example, the click behavior when a user browses a page can be regarded as an interaction event between the user and the content block of the page, and the purchase behavior in e-commerce can be regarded as the interaction event between the user and the product. The interaction events between users, the communication between users through social platforms, and the transfer behavior between accounts are the interaction events between users. A series of user interaction events contains the characteristics of the user's fine-grained habits and preferences, as well as the characteristics o...
