充分利用Twitter固有的特征来检测Twitter上的社交垃圾邮件

Making the Most of Tweet-Inherent Features for Social Spam Detection on Twitter

Bo Wang, Arkaitz Zubiaga, Maria Liakata, Rob Procter

摘要:

社交垃圾邮件在Twitter等社交媒体服务上产生大量噪声,这降低了最终用户和数据采掘应用程序观察到的信噪比。现有的社交垃圾邮件检测技术主要集中在通过使用大量的历史和基于网络的数据来识别垃圾邮件帐户。在本文中,我们专注于垃圾推文的检测,优化的数据量,需要收集只依赖于推文固有的功能。这使得能够以及时的方式将垃圾邮件检测系统应用于大量推文,潜在地可应用于实时或近实时设置。使用两个大的手标记的数据集的推文包含垃圾邮件,我们研究了五个分类算法和四个不同的功能集的社会垃圾邮件检测任务的适用性。我们的研究结果表明,通过使用有限的一组功能,在一条推文中,我们可以实现令人鼓舞的结果相比,现有的垃圾邮件发送者检测系统,利用额外的,昂贵的用户功能是有竞争力的。我们的研究是第一次尝试概括不同数据集上的最佳分类器和社交垃圾邮件检测功能集的结论。

英文摘要:

Social spam produces a great amount of noise on social media services such as Twitter, which reduces the signal-to-noise ratio that both end users and data mining applications observe. Existing techniques on social spam detection have focused primarily on the identification of spam accounts by using extensive historical and network-based data. In this paper we focus on the detection of spam tweets, which optimises the amount of data that needs to be gathered by relying only on tweet-inherent features. This enables the application of the spam detection system to a large set of tweets in a timely fashion, potentially applicable in a real-time or near real-time setting. Using two large hand-labelled datasets of tweets containing spam, we study the suitability of five classification algorithms and four different feature sets to the social spam detection task. Our results show that, by using the limited set of features readily available in a tweet, we can achieve encouraging results which are competitive when compared against existing spammer detection systems that make use of additional, costly user features. Our study is the first that attempts at generalising conclusions on the optimal classifiers and sets of features for social spam detection over different datasets.
