The proposed 2-D offline evaluation strategy which accounts for the way users explore a two-dimensional recommendation carousel by concentrating on the top-left corner and then proceeding both to the right and to the bottom across different carousels.

It is common for video-on-demand and music streaming services to adopt a user interface composed of several recommendation lists, i.e. widgets or swipeable carousels, each generated according to a specific criterion or algorithm (e.g. most recent, top popular, recommended for you, editors' choice, etc.). Selecting the appropriate combination of car...

... this paper we propose a definition for this carousel setting highlighting the specific characteristics that distinguish both the user interface and the user behavior from the traditional single list evaluation. We also propose a 2-D strategy for the offline evaluation tailored for a carousel setting as well as a ranking metric which takes into account how users explore such interfaces (see Figure 3). We finally report experimental results indicating that accounting for the carousel interface and user behavior changes the relative performance of recommendation models such that they lead to a different conclusion on which should be the carousel to display. ...

Repetition in music consumption is a common phenomenon. It is notably more frequent when compared to the consumption of other media, such as books and movies. In this paper, we show that one particularly interesting repetitive behavior arises when users are consuming new items. Users' interest tends to rise with the first repetitions and attains a...
