How to model explicit+implicit datasets?

[amirj]

It seems that all available datasets contains only explicit feedbacks (user_ids, items_ids, ratings) and the assumption is that the implicit model leverages only (user_ids, item_ids). So, how can I model a dataset which contains an explicit feedback and a set of implicit feedbacks?

This is a great question. I would point you towards this paper for one possible approach.
