摘要:

社会媒体用户的社会经济属性(如职业和收入)的推断是计算社会科学中的一个重要问题。这些特征的自动推理在个性化推荐系统、有针对性的计算广告和在线政治竞选中有应用。虽然以前的工作已经表明,语言特征可以可靠地预测Twitter上的社会经济属性,但尚未针对如此复杂的用户特征探索使用来自用户社交网络的信息。在本文中,我们描述了一种方法,用于预测职业类和收入的Twitter用户给定的信息提取从他们的扩展网络通过学习低维向量表示的用户,即图嵌入。我们使用这种表示来训练职业类别和收入的预测模型。两个公开数据集的结果表明,我们的方法在这两个任务中始终优于最先进的方法。当我们将图嵌入与文本特征相结合时,我们还获得了进一步的显着改进,表明社交网络和语言信息是互补的。

英文摘要:

Inferring socioeconomic attributes of social media users such as occupation and income is an important problem in computational social science. Automated inference of such characteristics has applications in personalised recommender systems, targeted computational advertising and online political campaigning. While previous work has shown that language features can reliably predict socioeconomic attributes on Twitter, employing information coming from users' social networks has not yet been explored for such complex user characteristics. In this paper, we describe a method for predicting the occupational class and the income of Twitter users given information extracted from their extended networks by learning a low-dimensional vector representation of users, i.e. graph embeddings. We use this representation to train predictive models for occupational class and income. Results on two publicly available datasets show that our method consistently outperforms the state-of-the-art methods in both tasks. We also obtain further significant improvements when we combine graph embeddings with textual features, demonstrating that social network and language information are complementary.
