Crowds, Bluetooth, and Rock-n-Roll. Understanding Music Festival Participant Behavior
This work addresses understanding social dynamics and preferences in large-scale events for event organizers and researchers, but it is incremental as it applies existing sensing and modeling techniques to a new dataset.
The study analyzed participant behavior at a large music festival (8 days, 130,000+ participants) using Bluetooth scanners to collect mobility and interaction data, revealing clusters of concerts and participants based on music preferences and meta-features like genres and origins.
In this paper we present a study of sensing and analyzing an offline social network of participants at a large-scale music festival (8 days, 130,000+ participants). We place 33 fixed-location Bluetooth scanners in strategic spots around the festival area to discover Bluetooth-enabled mobile phones carried by the participants, and thus collect spatio-temporal traces of their mobility and interactions. We subsequently analyze the data on two levels. On the micro level, we run a community detection algorithm to reveal a variety of groups the festival participants form. On the macro level, we employ an Infinite Relational Model (IRM) in order to recover the structure of the social network related to participants' music preferences. The obtained structure in the form of clusters of concerts and participants is then interpreted using meta-information about music genres, band origins, stages, and dates of performances. We show that most of the concerts clusters can be described by one or more of the meta-features, effectively revealing preferences of participants (e.g. a cluster of US bands) and discuss the significance of the findings and the potential and limitations of the used method. Finally, we discuss the possibility of employing the described method and techniques for creating user-oriented applications and extending the sensing capabilities during large-scale events by introducing user involvement.
