Subject PredictionIO Universal Recommender user rating
Date Mon, 09 Oct 2017 17:23:08 GMT

I know there were a lot of question on this matter, I've looked everywhere
but didn't find a good answer.

I'm using the Universal Recommender to make a recommendation system for a
video sharing website.
I have a lot of details in terms of user behavior but the most important
one ( at least that's what I'm now ) is the amount of seconds consumed by a
visitor. A ration between the video length in seconds and the seconds the
visitor actually has seen from it.

Let's say that a visitor reached a landing page with a video with total
length of 60 seconds. If the user actually sees 60 seconds ( the video
player reports that the video played the entire 60 seconds ) I think I can
assume that the visitor gave an implicit score of 10 out of 10 for this

Is there a way I can include this value in the prediction system ? Or,
order the returned items by this value?

Thanks for reading this, any thought will be greatly appreciated.
