Described are example systems and methods generally directed to systems and methods for a real-time content recommendation service employing active guidance to facilitate efficient and effective recommendations of content to a user. A plurality of characteristic information associated with content items from a corpus of content items can be obtained and used to generate a content graph and a discovery map/decision tree. The discovery maps/decision trees may include content items and/or segments of content items that are arranged and connected in the discovery maps/decision trees based on their associated characteristic information to facilitate guided recommendations of content based on user interactions. The discovery map/decision tree may then be accessed to provide guided recommendations of content.

Actively guided content recommendation

Techniques for using a machine learning model to determine a proper subset of a multimedia file for a viewer based on their interest without the need to actively control a media player timeline are described. As one example, a computer-implemented method includes receiving a request at a content delivery service from a media player of a viewer to play a proper subset of a live multimedia file for a category of content of the live multimedia file without the viewer actively controlling a timeline of the media player of the viewer, determining an indication of a prior multimedia playing interaction of the viewer with the content delivery service, partitioning, by the content delivery service, the live multimedia file into a video portion, an audio portion, and a text portion, determining, by the content delivery service, one or more labels for the video portion, the audio portion, and the text portion, determining, by a machine learning model of the content delivery service, a proper subset of segments of the live multimedia file to send to the viewer based at least in part on the indication and the one or more labels, and live streaming the proper subset of segments of the live multimedia file to the media player of the viewer.
