摘要：本课题对手机新闻客户端的基本情况和研究现状进行梳理，了解了手机新闻客户端市场格局，人群分布特征。通过对实例“今日头条”个性化推荐的初步冷推荐以及保持用户粘度具体算法的表述得出两点结论：个性化推荐具有以人为本的信息分发优势，形成千人千面的阅读体验；同时也带来不可避免的局限性，个性化推荐会形成信息圈的闭环，导致用户难以走出自己关注的圈子。对此提出新闻客户端应加强人为干预，扩大信息范围；推荐算法定期模糊化，利用大数据进行信息相关性的链接，从而改良现有的个性化推荐。手机新闻客户端现状分析得出版权意识淡薄的问题。对此提出客户端加强信息来源管控；媒体之间进行接洽，合理共享新闻消息；标志新闻消息出处，尊重每一个人或集体的成果。81818
