METHOD AND DEVICE FOR PROCESSING INTERACTION SEQUENCE DATA

Document Type and Number:

WIPO Patent Application WO/2021/027260

Kind Code:

A1

Abstract:

A method and device for processing interaction sequence data. The method comprises: first obtaining a dynamic interaction graph constructed according to a dynamic interaction sequence, wherein the dynamic interaction sequence comprises a plurality of interaction events arranged according to a time sequence, and the dynamic interaction graph comprises nodes representing all interaction objects in all the interaction events, and any node i points to, by means of a connecting edge, two nodes corresponding to a previous interaction event in which an object represented by the node i participates; and then, in the dynamic interaction graph, determining a target sub-graph corresponding to a target node, the target sub-graph comprising nodes starting from the target node and arriving within a predetermined range via the connection edge. Therefore, a feature vector corresponding to the target node can be determined on the basis of node features of the nodes comprised in the target sub-graph and a pointing relationship of the connection edges between the nodes.
