我的年龄是多少?:利用影响力好友网络和DBpedia预测Twitter用户的年龄

What's my age?: Predicting Twitter User's Age using Influential Friend Network and DBpedia

Alan Smith, Manas Gaur

摘要:

社交媒体是用户行为和意见的丰富来源。Twitter每天从3.28亿用户中感知近5亿条推文。在这些信息上建立适当的机器学习管道,可以为各种领域(如社会科学、公共卫生、人群智慧等)提供最新且具有成本效益的数据汇集。在许多领域,用户人口统计信息是识别所研究人群细分的关键。例如,观察到哪些年龄组滥用哪些药物?哪个种族最受抑郁症的影响?Twitter目前不要求用户提供任何人口统计信息。我们建议创建一个机器学习系统,结合DBpedia图,预测Twitter用户最可能的年龄。在我们使用社交媒体文本和用户元数据构建年龄预测模型的过程中,我们探索了现有的最先进的方法。详细介绍我们的数据汇集,功能工程周期,模型选择和评估管道,我们将展示我们的方法的有效性,通过比较“预测平均”年龄估计基线。

英文摘要:

Social media is a rich source of user behavior and opinions. Twitter senses nearly 500 million tweets per day from 328 million users.An appropriate machine learning pipeline over this information enables up-to-date and cost-effective data collection for a wide variety of domains such as; social science, public health, the wisdom of the crowd, etc. In many of the domains, users demographic information is key to the identification of segments of the populations being studied. For instance, Which age groups are observed to abuse which drugs?, Which ethnicities are most affected by depression per location?. Twitter in its current state does not require users to provide any demographic information. We propose to create a machine learning system coupled with the DBpedia graph that predicts the most probable age of the Twitter user. In our process to build an age prediction model using social media text and user meta-data, we explore the existing state of the art approaches. Detailing our data collection, feature engineering cycle, model selection and evaluation pipeline, we will exhibit the efficacy of our approach by comparing with the "predict mean" age estimator baseline.
