‘Chain Reaction: Measuring Diversity on Online Streaming Platforms Through Fan Communities’

Presented by Julien M’Barki


Cultural diversity has received particular attention from public policies these two past decades. At the turn of the 21st century, cultural globalization is changing in nature: the rise of online platforms is shaking up the international circulation of cultural goods and raising new questions of diversity in music. 


Using Spotify’s API, we propose a new method to measure diversity on music streaming services. We present Chain Reaction, an algorithm which measures the distance between artists using Spotify’s feature “Fans also like”. It makes it possible to advance our understanding of diversity in the musical field, thanks to fan communities on streaming services.

This talk is held as part of Innovation Day.
