Dwell time has been widely used in various fields to evaluate content quality and user engagement. Although many studies shown that content with long dwell time is good quality, contents with short dwell time have not been discussed in detail. We hypothesize that content with short dwell time is not always low quality and does not always have low user engagement, but is instead related to user interest. The purpose of this study is to clarify the meanings of short dwell time browsing in mobile news application. First, we analyze the relation of short dwell time to user interest using large scale user behavior logs from a mobile news application. This analysis was conducted on a vector space based on users click histories and then users and articles were mapped in the same space. The users with short dwell time are concentrated on a specific position in this space; thus, the length of dwell time is related to their interest. Moreover, we also analyze the characteristics of short dwell time browsing by excluding these browses from their click histories. Surprisingly, excluding short dwell time click history, it was found that short dwell time click history included some aspect of user interest in 30.87% of instances where the cluster of users changed. These findings demonstrate that short dwell time does not always indicate a low level of user engagement, but also level of user interest.

新闻应用中与用户兴趣相关的短停留时间分析

停留时间已广泛用于各个领域，以评估内容质量和用户参与度。尽管许多研究表明，停留时间长的内容质量好，但停留时间短的内容尚未详细讨论。我们假设停留时间短的内容并不总是质量低劣，也不总是具有较低的用户参与度，而是与用户兴趣有关。这项研究的目的是阐明移动新闻应用程序中短停留时间浏览的含义。首先，我们使用来自移动新闻应用程序的大规模用户行为日志来分析短停留时间与用户兴趣之间的关系。此分析是根据用户点击历史记录在向量空间上进行的，然后将用户和文章映射到同一空间。停留时间短的用户集中在此空间中的特定位置；因此，停留时间的长短与他们的兴趣有关。此外，我们还将停留时间短的浏览特征从点击历史中排除，从而分析了这些停留时间。出乎意料的是，除了短停留时间单击历史记录外，发现短停留时间单击历史记录在30.87％的用户集群发生更改的实例中包括用户兴趣的某些方面。这些发现表明，短的停留时间并不总是表明用户参与度较低，而是用户的兴趣度较高。除了短停留时间点击历史记录以外，发现短停留时间点击历史记录在30.87％的用户集群发生变化的实例中包括用户兴趣的某些方面。这些发现表明，短的停留时间并不总是表明用户参与度较低，而是用户的兴趣度较高。除了短停留时间点击历史记录以外，发现短停留时间点击历史记录在30.87％的用户集群发生变化的实例中包括用户兴趣的某些方面。这些发现表明，短的停留时间并不总是表明用户参与度较低，而是用户的兴趣度较高。
