摘要： 在移动视频内容推送中,用户是否最终接受推送的视频内容不但取决于内容本身,还受用户所处的上下文(包括用户使用视频服务的时间、用户所在的位置,以及用户所使用接受视频内容的设备)的影响。上下文对用户接受移动视频内容的影响对移动视频推送具有重要意义。通过数据驱动的方法,利用大量移动用户在真实移动视频服务中接受视频推荐的记录(包括16天共4千万条移动视频访问日志),研究包括时间、位置、设备等上下文信息对用户最终接受移动视频内容的影响。基于实验数据给出的发现包括:(1)时间的周期性和峰值差异性；(2)位置的差异性和特殊区域的不同影响；(3)移动设备类型、移动操作系统的不同影响。这些研究结果将有助于优化移动视频内容的推送,提高用户的移动视频服务体验,例如,用户可以在偏好的上下文背景下获得更好的移动视频推送服务。
