摘要
The present disclosure relates to systems and methods for updating a sequence of services. The systems may perform the methods to establish a network communication with the user terminal; obtain, from the user terminal, an identification associated with a user account registered with the system; obtain a current sequence of the plurality of services associated with the identification; determine whether a condition for updating the current sequence is satisfied, when the condition for updating the current sequence is not satisfied, send the current sequence of the plurality of services to the user terminal; and when the condition for updating the current sequence is satisfied, determine an updated sequence of the plurality of services displayed on the display of the user terminal.

In step 520, acquisition module 310 may obtain a DCG value of the optimized sequence of the plurality of services.
Sorting module 340 may determine an optimized sequence according to the travel value. In some embodiments, sorting module 340 may sort the services according to their travel values.
In step 530, evaluation module 330 may determine an NDCG value based on the DCG values of the current sequence of the plurality of services and the DCG values of the optimized sequence of the plurality of services.
