Obtaining learning duration corresponding to a user to be recommended from user information
Wherein the login preference information includes a login preference period indicating a period in which the user logs in the most number of times. Correspondingly, the preset login time period to which the login time belongs in each login record is obtained, the number of the login time included in the preset time period is determined as the login frequency corresponding to the preset time period, and the preset time period with the highest login frequency is used as the login preference time period.
Optionally, accessing the login preference information further comprises learning a preference period. The log-in record further includes a learning start time and a learning end time. Correspondingly, the preset time interval to which the learning starting time in each login record belongs is obtained, the number of the learning starting times included in the preset time interval is determined as the learning times corresponding to the preset time interval, and the preset time interval with the highest learning times is used as the learning preference time interval.
