摘要:

这项工作概述了我们如何优先考虑原创新闻,这是新闻质量的关键指标。通过研究我们社交媒体平台上新闻帖子的景观和生命周期,我们确定了建立和部署原创性评分的挑战。我们追求一种基于标准化PageRank值和三步聚类的方法,并每小时刷新分数以捕捉在线新闻的动态。我们描述了一个近实时的系统架构,评估我们的方法,并将其部署到生产。我们的实证结果验证了各个组成部分,并表明,优先考虑原始新闻增加了用户与新闻的互动,并提高了专有的累积指标。

英文摘要:

This work outlines how we prioritize original news, a critical indicator of news quality. By examining the landscape and life-cycle of news posts on our social media platform, we identify challenges of building and deploying an originality score. We pursue an approach based on normalized PageRank values and three-step clustering, and refresh the score on an hourly basis to capture the dynamics of online news. We describe a near real-time system architecture, evaluate our methodology, and deploy it to production. Our empirical results validate individual components and show that prioritizing original news increases user engagement with news and improves proprietary cumulative metrics.
