Methods and systems for providing media recommendations based on implicit user behavior

摘要

A server system that provides a content service determines a preference of a first user of the content service for a first media item. The preference has a magnitude and is either positive or negative. The server system provides the first media item for playback based on a request from an application that is executing on a mobile electronic device of the first user with an audio jack and a speaker. The server system receives data indicating that playback of the first media item by the mobile electronic device is through the speaker and modifies the magnitude of the preference, which includes increasing the magnitude of the preference based on the received data. The server system generates a media recommendation for the first user in accordance with the modified preference and provides the media recommendation to the mobile electronic device.
