在线社交网络中的异常检测

Anomaly detection in online social networks

摘要:

在线社交网络中的异常可能意味着不规则的,通常是非法的行为。在线社交网络中的异常可能意味着不规则的,通常是非法的行为。对这种异常的检测已被用于识别恶意个体,包括垃圾邮件发送者、性掠夺者和在线欺诈者。在本文中,我们调查现有的计算技术检测异常在线社交网络。我们将异常划分为静态或动态,标记或未标记,并调查检测这些不同类型异常的方法。我们认为,在线社交网络中的异常检测由两个子过程组成:网络特征的选择和计算,以及从该特征空间对观察结果进行分类。此外,本文还概述了异常检测可以解决的问题类型,并确定了未来研究的关键领域。

英文摘要:

Anomalies in online social networks can signify irregular, and often illegal behaviour. Anomalies in online social networks can signify irregular, and often illegal behaviour. Detection of such anomalies has been used to identify malicious individuals, including spammers, sexual predators, and online fraudsters. In this paper we survey existing computational techniques for detecting anomalies in online social networks. We characterise anomalies as being either static or dynamic, and as being labelled or unlabelled, and survey methods for detecting these different types of anomalies. We suggest that the detection of anomalies in online social networks is composed of two sub-processes; the selection and calculation of network features, and the classification of observations from this feature space. In addition, this paper provides an overview of the types of problems that anomaly detection can address and identifies key areas of future research.
