How Video Recommendation Works

How Video Recommendation Works
21 Apr 2017

What is Video Recommendation

Through the process of video recommendation, we get suggested video content, based on our user profile and interests. Video recommendation is not a simple task, but a whole set of algorithms, which facilitate our quality viewing experience.

Video streaming platforms usually provide advanced tools for easy discovery of relevant content from the moment we first interact with the application. The video recommendation engine collects data from multiple sources to build a complete user profile.

Video-based Methods for Building Recommendations

Recommendation engines aggregate video-based data to provide us quality suggestions. Some of the methods include creating Related Videos List, which is calculated for each video. Thus, every video is interrelated with a ‘bucket’ of similar videos.

Another advanced method for enhancing video recommendations is the integration with machine learning algorithms. A popular machine learning algorithm, used in sophisticated video streaming platforms, is based on Apache Mahout.

Applying the video-based methods facilitates effective recommendations, where the viewer gets suggestions, based on related videos, which are from the same ‘bucket’ only. Based on techniques like content similarity the engines build highly relevant content lists depending on the context in which we are viewing and the type of content we are browsing through.

User-based Methods for Building Complete User Profile

User-based methods for building complete user profile include sources like demographics data and personal interests from Facebook, explicit choice of interests during onboarding process. Behavioral data points like watched type of content (news, movies, series, clips, live events, etc.) and what videos are watched, from which genres, provides another important flow of data to video recommendation engines.

Collected data then is used as input for building personal recommendations lists organized by topics, genres, what other users watched, etc.

User-based video content targeting includes techniques like collaborative filtering based on sentiments of similar users and content-based filtering from selected videos (last N watched; top search results for user’s related interests).

User similarity is usually defined, based on machine learning algorithms and available user profile properties matching.
