Beyond the Surface: Investigating Explicit and Implicit Perceptions of Music Diversity

Diversity has been an important concept in both interactive information retrieval (IIR) and recommendation systems (RS), especially in the context of entertainment activities such as music, video, or games.However, diversity itself is a highly abstract concept, and providing diversity to users brings the risk of unsatisfactory results.In this short paper, we investigate diversity in the context of music recommendation.We conducted an online survey with 149 participants to investigate how they perceive music diversity.Our results revealed their explicit ideas about different aspects of diversity, as well as their underlying perceptions shaping their diversity preferences.We propose viewing music diversity using an "above and below-surface" structure, and our findings can help design other entertainment systems such as video or games.
