Resumo(s)
The present dissertation focuses on proposing and describing a collaborative filtering approach for
Music Recommender Systems. Music Recommender Systems, which are part of a broader class of
Recommender Systems, refer to the task of automatically filtering data to predict the songs that are
more likely to match a particular profile.
So far, academic researchers have proposed a variety of machine learning approaches for determining
which tracks to recommend to users. The most sophisticated among them consist, often, on complex
learning techniques which can also require considerable computational resources. However, recent
research studies proved that more simplistic approaches based on nearest neighbors could lead to
good results, often at much lower computational costs, representing a viable alternative solution to
the Music Recommender System problem.
Throughout this thesis, we conduct offline experiments on a freely-available collection of listening
histories from real users, each one containing several different music tracks. We extract a subset of 10
000 songs to assess the performance of the proposed system, comparing it with a Popularity-based
model approach. Furthermore, we provide a conceptual overview of the recommendation problem,
describing the state-of-the-art methods, and presenting its current challenges. Finally, the last section
is dedicated to summarizing the essential conclusions and presenting possible future improvements.
