从新闻中学习:预测Twitter上的实体流行度

Learning from the News: Predicting Entity Popularity on Twitter

Pedro Saleiro, Carlos Soares

摘要:

在这项工作中,我们解决了基于新闻周期预测实体在Twitter上受欢迎程度的问题。我们应用监督学习方法并提取四种类型的特征:(i)信号,(ii)文本,(iii)情感和(iv)语义,我们使用这些特征来预测给定实体的受欢迎程度在接下来的几个小时内是高还是低。我们在超过1.5亿条推文和500万条新闻的数据集中对六个不同的实体进行了几次实验,并获得了超过0.70的F1分数。错误分析表明,当新闻是事件的主要信息源时,新闻在预测实体在Twitter上的受欢迎程度方面表现得更好,而不是电视直播,政治辩论或足球比赛等事件。

英文摘要:

In this work, we tackle the problem of predicting entity popularity on Twitter based on the news cycle. We apply a supervised learn- ing approach and extract four types of features: (i) signal, (ii) textual, (iii) sentiment and (iv) semantic, which we use to predict whether the popularity of a given entity will be high or low in the following hours. We run several experiments on six different entities in a dataset of over 150M tweets and 5M news and obtained F1 scores over 0.70. Error analysis indicates that news perform better on predicting entity popularity on Twitter when they are the primary information source of the event, in opposition to events such as live TV broadcasts, political debates or football matches.
