Abstract

Systems and methods for identifying, in a network environment in which users watch videos that are downloaded or streamed over a network, a video in which a user is likely to be interested based on session context. For example, a server or other computing system identifies prior session contexts in which prior users watched videos and session progress data for prior sessions in which these prior users watched the videos. The server or other computing system determines a session context of a user for whom a video is to be recommended. For this user, the server or other computing system generates a recommendation identifying one or more videos in which the user is likely to be interested, where the user has not previously watched the recommended videos. The recommendation is generated based on the prior session contexts, the session progress data, and the session context of the user.

First claim

What is claimed is:

1. A computer-implemented method for recommending video content in a network environment in which users watch videos that are downloaded or streamed over a network, the method comprising:
identifying, by a processing device, prior session contexts in which prior users watched videos and session progress data for prior sessions in which the prior users watched the videos;
building, by the processing device, an interest-estimation model from the prior session contexts and the session progress data, wherein building the interest-estimation model comprises:
identifying a feature set comprising (i) user features comprising characteristics specific to the prior users, (ii) video features comprising characteristics specific to the videos, and (iii) session features comprising characteristics specific to the prior sessions,
determining that a first feature in the feature set is dependent on a second feature in the feature set,
reducing the feature set for use by a factorization machine model, wherein reducing the feature set comprises selecting a feature subset comprising one or more of the user features, one or more of the video features, and one or more of the session features, wherein the first feature is omitted from the feature subset based on the first feature being dependent on the second feature, and
estimating, based on a weighted combination of the feature subset provided by the factorization machine model, a set of user interests for videos associated with a set of contexts;

determining, by the processing device, a session context of a current user;
generating, by the processing device, a recommendation identifying a video in which the current user is likely to be interested and that has not been previously watched by the current user, wherein the processing device generates the recommendation based on the session context matching one of the set of contexts; and
causing, by the processing device and based on the recommendation, a content server to transmit the video to a user device associated with the current user.

2. The method of claim 1 , wherein generating the recommendation comprises recommending a subset of videos from a set of videos to the current user, and further comprising providing, responsive to a selection input from the current user, the video from the subset of videos recommended.

3. The method of claim 1 , wherein the recommendation is also generated based on user ratings included in information describing the prior sessions.

4. The method of claim 1 , wherein the session context is a type of device or operating system that the current user is currently using.

5. The method of claim 1 , wherein the session context comprises data describing a context of the current user.

6. The method of claim 5 , wherein the data describing the context of the current user comprises at least one of:
a demographic for the current user;
a current time of day for the current user; or
a current geographic location of the current user.

7. The method of claim 1 , wherein the session context comprises data describing a video context.

8. The method of claim 1 , wherein the session context comprises data describing attributes specific to a session.

9. The method of claim 1 , wherein the session progress data is generated by the processing device based on consumption data identifying how much of the videos the prior users watched.

10. A system comprising:
a processing device; and
a non-transitory computer readable medium communicatively coupled to the processing device,
wherein the processing device is configured for executing instructions stored on the non-transitory computer-readable medium and thereby performing operations comprising:
identifying prior session contexts in which prior users watched videos and session progress data for prior sessions in which the prior users watched the videos;
building an interest-estimation model from the prior session contexts and the session progress data, wherein building the interest-estimation model comprises:
identifying a feature set comprising (i) user features comprising characteristics specific to the prior users, (ii) video features comprising characteristics specific to the videos, and (iii) session features comprising characteristics specific to the prior sessions,
determining that a first feature in the feature set is dependent on a second feature in the feature set,
reducing the feature set for use by a factorization machine model, wherein reducing the feature set comprises selecting a feature subset comprising one or more of the user features, one or more of the video features, and one or more of the session features, wherein the first feature is omitted from the feature subset based on the first feature being dependent on the second feature, and
estimating, based on a weighted combination of the feature subset provided by the factorization machine model, a set of user interests for videos associated with a set of contexts;

determining a session context of a current user;
generating a recommendation identifying a video in which the current user is likely to be interested and that has not been previously watched by the current user, wherein the processing device generates the recommendation based on the session context matching one of the set of contexts; and
causing a content server to transmit the video to a user device associated with the current user.

11. The system of claim 10 , wherein generating the recommendation comprises recommending a subset of videos from a set of videos to the current user, and further comprising providing, responsive to a selection input from the current user, the video from the subset of videos recommended.

12. The system of claim 10 , wherein the processing device is further configured for generating the recommendation based on user ratings included in information describing the prior sessions.

13. The system of claim 10 , wherein the session context is a type of device or operating system that the current user is currently using.

14. The system of claim 10 , wherein the session context comprises data describing at least one of:
a demographic for the current user;
a current time of day for the current user; or
a current geographic location of the current user.

15. The system of claim 10 , wherein the session context comprises data describing a video context.

16. The system of claim 10 , wherein the session context comprises data describing attributes specific to a session.

17. A non-transitory computer readable medium storing program code executable by a processing device, wherein the program code comprises:
program code for identifying prior session contexts in which prior users watched videos and session progress data for prior sessions in which the prior users watched the videos;
program code for building an interest-estimation model from the prior session contexts and the session progress data, wherein building the interest-estimation model comprises:
identifying a feature set comprising (i) user features comprising characteristics specific to the prior users, (ii) video features comprising characteristics specific to the videos, and (iii) session features comprising characteristics specific to the prior sessions,
determining that a first feature in the feature set is dependent on a second feature in the feature set,
reducing the feature set for use by a factorization machine model, wherein reducing the feature set comprises selecting a feature subset comprising one or more of the user features, one or more of the video features, and one o
