论文摘要
音乐消费中的重复是一种普遍现象。与其他媒体（例如书籍和电影）的消费相比，它的频率明显更高。在本文中，我们表明，当用户食用新项目时，就会出现一种特别有趣的重复行为。用户的兴趣往往会随着第一次重复而上升，并达到高峰，此后随后的暴露率将减少兴趣，从而导致倒置。这种行为已在心理学中进行了广泛的研究，称为单纯的暴露效应。在本文中，我们展示了有关单纯的暴露效果的文献中有许多因素和基于用户的因素如何调节效果的幅度。由于用户每天在音乐流媒体平台中发现新歌曲的数据的广泛可用性，因此这些发现使新方法可以表征音乐，用户及其关系。最终，它开辟了基于这些特征的新推荐系统范例的可能性。
Repetition in music consumption is a common phenomenon. It is notably more frequent when compared to the consumption of other media, such as books and movies. In this paper, we show that one particularly interesting repetitive behavior arises when users are consuming new items. Users' interest tends to rise with the first repetitions and attains a peak after which interest will decrease with subsequent exposures, resulting in an inverted-U shape. This behavior, which has been extensively studied in psychology, is called the mere exposure effect. In this paper, we show how a number of factors, both content and user-based, well documented in the literature on the mere exposure effect, modulate the magnitude of the effect. Due to the vast availability of data of users discovering new songs everyday in music streaming platforms, these findings enable new ways to characterize both the music, users and their relationships. Ultimately, it opens up the possibility of developing new recommender systems paradigms based on these characterizations.
