The application provides an O2O service recommendation method and
system based on preference spatio-temporal evolution analysis, a storage medium and an electronic device, and relates to the field of O2O service recommendation.In the application, firstly, an O2O
consumer set, an O2O
service set and a service category set are acquired, and a service
score matrix and a service category matrix are constructed;then, based on the preference changes of consumers in
service selection, evaluation and selected service geographic location, three different dynamic similarities are acquired;then, different dynamic similarities are fused to acquire a dynamic preference similarity;finally, for a target
consumer, the dynamic preference similarity is used to sort its neighbors, and the priority of O2O service is recommended.Based on the spatio-temporal evolution of the preference of the
consumer, the dynamic similarity is proposed, which more accurately measures the relationship between the consumers, thereby improving the recommendation performance of the O2O service.The experimental results show that the proposed dynamic similarity has high accuracy and can effectively reflect the strong consumer relationship.
