🎯 Definition
The Recommendation Coverage is a metric used to assess the recommendation system.
It computes the proportion of recommended items watched by your end-users in a given timeframe.
Example
In my catalogue, 500 items have been recommended by Rumo. Out of these 500 items, 100 have the interaction “watch”.
In that case, we have a recommendation coverage of 20 %
So, to put it differently, the users watched 20 % of the items recommended.
Precisions
ℹ️ By Watch, we refer to the interaction “watch” supported by Rumo and integrated in your system.
ℹ️ By Recommendation, we refer to both content-to-content and personalized recommendations.
