Current Challenges and Visions in Music Recommender Systems Research
Music recommender systems (MRS) have experienced a boom in recent years,
thanks to the emergence and success of online streaming services, which
nowadays make available almost all music in the world at the user's fingertip.
While today's MRS considerably help users to find interesting music in these
huge catalogs, MRS research is still facing substantial challenges. In
particular when it comes to build, incorporate, and evaluate recommendation
strategies that integrate information beyond simple user--item interactions or
content-based descriptors, but dig deep into the very essence of listener
needs, preferences, and intentions, MRS research becomes a big endeavor and
related publications quite sparse.
The purpose of this trends and survey article is twofold. We first identify
and shed light on what we believe are the most pressing challenges MRS research
is facing, from both academic and industry perspectives. We review the state of
the art towards solving these challenges and discuss its limitations. Second,
we detail possible future directions and visions we contemplate for the further
evolution of the field. The article should therefore serve two purposes: giving
the interested reader an overview of current challenges in MRS research and
providing guidance for young researchers by identifying interesting, yet
under-researched, directions in the field
User Privacy on Spotify: Predicting Personal Data from Music Preferences
openThe way we listen to music has changed drastically in the past decade. Now we can play any
kind of music from various artists around the world through our smart devices. Many music
streaming providers, if not most, are built with systems to track usersâ music preferences and
suggest new content.
The music we listen to reveals a great deal about who we are. In general, people share their
playlists and songs of their favorite artists on the music platform; find people with common
music genres and connect with them. It is not always easy to make friends with unknown
people, but music is a good way to accomplish that. In spite of that, we must also look at other
sides of the coin from a security perspective. Is it a good idea to share music interests with
others or will it compromise our privacy? According to privacy experts and developers, there
is no purposeless data. Everything can be used to infer private information, even a single like
on social media, which seems, at first sight, meaningless, but it can reveal more information
than it promises. In the case that our musical tastes reveal our information, we may be profiled
for targeted advertisement, by surveillance agencies, or in general, become potential victims of
malicious activities Since music is part of our daily lives, and there are many providers that let
us listen to music, we are even more at risk of being profiled and having our data sold.
In this research, we demonstrate the feasibility of inferring personal data based on playlists
and songs people publicly shared on Spotify. Through an online survey, we collected a new
dataset containing the private information of 750 Spotify users and we downloaded around
402,999 songs extracted from a total of 8777 playlists. Our statistical analysis shows significant
correlations between usersâ music preferences (e.g., music genre) and private information (e.g.,
age, gender, economic status).
As a consequence of significant correlations, we built several machine-learning models to
infer private information and our results demonstrated that such inference is possible, posing
a real privacy threat to all music listeners. In particular, we accurately predicted the gender
(71.7% f1-score), and several other private attributes, such as whether a person drinks (62.8%
f1-score) or smokes (60.2% f1-score) regularly.
The purpose of this project is to raise awareness about how seemingly purposeless data can
reveal personal information and educate users about how to better protect their privacy.The way we listen to music has changed drastically in the past decade. Now we can play any

Environmental Changes and the Dynamics of Musical Identity
Musical tastes reflect our unique values and experiences, our relationships
with others, and the places where we live. But as each of these things changes,
do our tastes also change to reflect the present, or remain fixed, reflecting
our past? Here, we investigate how where a person lives shapes their musical
preferences, using geographic relocation to construct quasi-natural experiments
that measure short- and long-term effects. Analyzing comprehensive data on over
16 million users on Spotify, we show that relocation within the United States
has only a small impact on individuals' tastes, which remain more similar to
those of their past environments. We then show that the age gap between a
person and the music they consume indicates that adolescence, and likely their
environment during these years, shapes their lifelong musical tastes. Our
results demonstrate the robustness of individuals' musical identity, and shed
new light on the development of preferences.Comment: Accepted to be published at ICWSM'1
Simulating activities: Relating motives, deliberation, and attentive coordination
Activities are located behaviors, taking time, conceived as socially meaningful, and usually involving interaction with tools and the environment. In modeling human cognition as a form of problem solving (goal-directed search and operator sequencing), cognitive science researchers have not adequately studied âoff-taskâ activities (e.g., waiting), non-intellectual motives (e.g., hunger), sustaining a goal state (e.g., playful interaction), and coupled perceptual-motor dynamics (e.g., following someone). These aspects of human behavior have been considered in bits and pieces in past research, identified as scripts, human factors, behavior settings, ensemble, flow experience, and situated action. More broadly, activity theory provides a comprehensive framework relating motives, goals, and operations. This paper ties these ideas together, using examples from work life in a Canadian High Arctic research station. The emphasis is on simulating human behavior as it naturally occurs, such that âworkingâ is understood as an aspect of living. The result is a synthesis of previously unrelated analytic perspectives and a broader appreciation of the nature of human cognition. Simulating activities in this comprehensive way is useful for understanding work practice, promoting learning, and designing better tools, including human-robot systems
Chapter Introduction and Overview
Drawing on perspectives from music psychology, cognitive neuroscience, philosophy, musicology, clinical psychology, and music education, Music and Mental Imagery provides a critical overview of cutting-edge research on the various types of mental imagery associated with music. The four main parts cover an introduction to the different types of mental imagery associated with music such as auditory/musical, visual, kinaesthetic, and multimodal mental imagery; a critical assessment of established and novel ways to measure mental imagery in various musical contexts; coverage of different states of consciousness, all of which are relevant for, and often associated with, mental imagery in music, and a critical overview of applications of mental imagery in health, educational ,and performance settings. By both critically reviewing up-to-date scientific research and offering new empirical results, this book provides a unique overview of the different types and origins of mental imagery in musical contexts, various ways to measure them, and intriguing insights into related mental phenomena such as mind-wandering and synaesthesia. This will be of particular interest for scholars and researchers of music psychology and music education. It will also be useful for practitioners working with music in applied health and educational contexts
El diseño de materiales para el desarrollo de la Competencia Intercultural Comunicativa en el aula de ILE
This present paper explores, analyses, proves and tries to provide a solution to the patent need for Intercultural Communicative Competence Development that a group of 56 students of first year of post-compulsory education portray. Thus, trough the convergence of different fields of study ranging from Intercultural Communicative Competence, Communicative Language Teaching and Second Language Acquisition, this document presents a needs analysis and a subsequent pedagogical intervention proposal that aims to erode the existing prejudices in young students today and to promote intercultural interaction by raising their awareness and by providing them with the necessary tools to reflect on themselves and on the others in a more tolerant, thoughtful and communicative way. The pedagogical intervention proposal has been nominated as âTen Mini-Pills for Intercultural Communicative Competence Developmentâ in which students are faced with concrete examples of the elements that shape other cultures so as for them to be able to deconstruct their cosmovision and thus integrate the reality of others. The âTen Mini-Pills for Intercultural Communicative Competence Developmentâ have been designed in the light of adaptability and easy implementation, so as for them to not only meet the needs of this concrete group of students but of as many as possible. <br /
Prediction, evolution and privacy in social and affiliation networks
In the last few years, there has been a growing interest in studying online social and affiliation networks, leading to a new category of inference problems that consider the actor characteristics and their social environments. These problems have a variety of applications, from creating more effective marketing campaigns to designing better personalized services. Predictive statistical models allow learning hidden information automatically in these networks but also bring many privacy concerns. Three of the main challenges that I address in my thesis are understanding 1) how the complex observed and unobserved relationships among actors can help in building better behavior models, and in designing more accurate predictive algorithms, 2) what are the processes that drive the network growth and link formation, and 3) what are the implications of predictive algorithms to the privacy of users who share content online.
The majority of previous work in prediction, evolution and privacy in online social networks has concentrated on the single-mode networks which form around user-user links, such as friendship and email communication. However, single-mode networks often co-exist with two-mode affiliation networks in which users are linked to other entities, such as social groups, online content and events. We study the interplay between these two types of networks and show that analyzing these higher-order interactions can reveal dependencies that are difficult to extract from the pair-wise interactions alone. In particular, we present our contributions to the challenging problems of collective classification, link prediction, network evolution, anonymization and preserving privacy in social and affiliation networks. We evaluate our models on real-world data sets from well-known online social networks, such as Flickr, Facebook, Dogster and LiveJournal
