A computer-implemented reminding method, comprising: determining an inactive user, wherein a user is determined to be an inactive user, if he or she is a user of a cloud service, who does not utilize relevant functions of the cloud service within a predefined time period; judging whether the inactive user is in an arousable state; and if the inactive user is not in the arousable state, performing no operation; and if the inactive user is in the arousable state, sending reminding information to the inactive user, that reminds the inactive user to reuse a corresponding function provided by the server, characterized in that the sending reminding information to the inactive user comprises - acquiring contact information of the inactive user by scanning the communication records and acquiring communication records of all the other active users of the cloud service in addition to the inactive user of the cloud service; judging whether the communication records scanning result contains a communication entry between an active user of the cloud service and the inactive user; and, if yes, extracting the contact information for the inactive user from the communication entry, and, in the step of judging whether the inactive user is in the arousable state, determining that the inactive user is in the arousable state; - sending the reminding information to the inactive user according to the contact information. determining an inactive user, wherein a user is determined to be an inactive user, if he or she is a user of a cloud service, who does not utilize relevant functions of the cloud service within a predefined time period; judging whether the inactive user is in an arousable state; and if the inactive user is not in the arousable state, performing no operation; and if the inactive user is in the arousable state, sending reminding information to the inactive user, that reminds the inactive user to reuse a corresponding function provided by the server, characterized in that the sending reminding information to the inactive user comprises - acquiring contact information of the inactive user by scanning the communication records and acquiring communication records of all the other active users of the cloud service in addition to the inactive user of the cloud service; judging whether the communication records scanning result contains a communication entry between an active user of the cloud service and the inactive user; and, if yes, extracting the contact information for the inactive user from the communication entry, and, in the step of judging whether the inactive user is in the arousable state, determining that the inactive user is in the arousable state; - sending the reminding information to the inactive user according to the contact information. - acquiring contact information of the inactive user by scanning the communication records and acquiring communication records of all the other active users of the cloud service in addition to the inactive user of the cloud service; judging whether the communication records scanning result contains a communication entry between an active user of the cloud service and the inactive user; and, if yes, extracting the contact information for the inactive user from the communication entry, and, in the step of judging whether the inactive user is in the arousable state, determining that the inactive user is in the arousable state; scanning the communication records and acquiring communication records of all the other active users of the cloud service in addition to the inactive user of the cloud service; judging whether the communication records scanning result contains a communication entry between an active user of the cloud service and the inactive user; and, if yes, extracting the contact information for the inactive user from the communication entry, and, in the step of judging whether the inactive user is in the arousable state, determining that the inactive user is in the arousable state; - sending the reminding information to the inactive user according to the contact information.
