Abstract: To evaluate various service recommendation strategies in complex environments for selecting the most appropriate service operation strategy and to improve the quality of Online to Offline (O2O) service recommendation,by utilizing the computational experiments method,O2O service recommendation strategies were researched from three aspects,which included the service recommendation strategy design (collaborative filtering recommendation strategy,context-based collaborative filtering recommendation strategy and the recommendation strategy considering context and service status),the construction of experiment system and the experiment evaluation analysis of service operation strategy.Through the computational experiments,the performance of recommendation strategy considering context and service status was optimal under different demand scenarios.
