Listener Modeling and Context-aware Music Recommendation Based on Country Archetypes
Music preferences are strongly shaped by the cultural and socio-economic
background of the listener, which is reflected, to a considerable extent, in
country-specific music listening profiles. Previous work has already identified
several country-specific differences in the popularity distribution of music
artists listened to. In particular, what constitutes the "music mainstream"
strongly varies between countries. To complement and extend these results, the
article at hand delivers the following major contributions: First, using
state-of-the-art unsupervised learning techniques, we identify and thoroughly
investigate (1) country profiles of music preferences on the fine-grained level
of music tracks (in contrast to earlier work that relied on music preferences
on the artist level) and (2) country archetypes that subsume countries sharing
similar patterns of listening preferences. Second, we formulate four user
models that leverage the user's country information on music preferences. Among
others, we propose a user modeling approach to describe a music listener as a
vector of similarities over the identified country clusters or archetypes.
Third, we propose a context-aware music recommendation system that leverages
implicit user feedback, where context is defined via the four user models. More
precisely, it is a multi-layer generative model based on a variational
autoencoder, in which contextual features can influence recommendations through
a gating mechanism. Fourth, we thoroughly evaluate the proposed recommendation
system and user models on a real-world corpus of more than one billion
listening records of users around the world (out of which we use 369 million in
our experiments) and show its merits vis-a-vis state-of-the-art algorithms that
do not exploit this type of context information.Comment: 30 pages, 3 tables, 12 figure
