2 Jan 2023 | | Abstract: | This paper illustrates the technologies of user next intent prediction with a
concept knowledge graph. The system has been deployed on the Web at Alipay,
serving more than 100 million daily active users. Specifically, we propose
AlipayKG to explicitly characterize user intent, which is an offline concept
knowledge graph in the Life-Service domain modeling the historical behaviors of
users, the rich content interacted by users and the relations between them. We
further introduce a Transformer-based model which integrates expert rules from
the knowledge graph to infer the online user’s next intent. Experimental
results demonstrate that the proposed system can effectively enhance the
performance of the downstream tasks while retaining explainability. | | Source: | arXiv, 2301.00503 | | Services: | Forum | Review | PDF | Favorites | |
