Abstract: A system can receive a request for a transport service from a rider device and can determine that a destination location information has not been included in the request. The system can arrange the transport service to be provided by a driver for the rider. The driver can be associated with a profile that includes data indicating that the driver has a particular characteristic. Based on determining that the destination location information has not been included in the request and determining that the driver has the particular characteristic, the system can transmit, to the rider device, a notification requesting the rider to provide a user-specified destination.

Abstract: A method of controlling the presentation of content instances using a processing system. The method involves causing the processing system to present one or more content instances to the user in accordance with a content network. The processing system then determines one or more responses provided by the user in response to the presentation of the content instance, before using the responses to evaluate the content in accordance with predetermined criteria. Following the evaluation the processing system modifies the content network to thereby vary the content presented in future.
