A survey of data mining and social network analysis based anomaly detection techniques

Abstract: With the increasing trend of online social networks in different domains, social network analysis has recently become the center of research. Online Social Networks (OSNs) have fetched the interest of researchers for their analysis of usage as well as detection of abnormal activities. Anomalous activities in social networks represent unusual and illegal activities exhibiting different behaviors than others present in the same structure. This paper discusses different types of anomalies and their novel categori… Show more

“…Mobile ad-hoc networks (MANETs) describe temporary cellular networks that are made of mobile nodes which utilize a similar randomaccess wireless channel in which the mobile nodes act as the hosts and routers [1,7]. Examples of MANETs are vehicular ad hoc networks (VANET), intelligent vehicular ad-hoc networks (InVANETs) and Internet-based mobile ad-hoc networks (iMANETs).…”

“…Social network sites are online settings that allow users to register and connect to each other to communicate or share resources and have a primary focus on social interpersonal communication [1]. Social networks have become a communication platform where different users with a personalized user profile interact and share information with each other [2]. In SNW people create, share, and exchange information and ideas [3].…”

“…This drawback will lead to a state of deceived high prediction accuracy, or generally known as imbalanced class distribution. Apart from that, the work also emphasized that obtaining accurate and representative labels, particularly for anomaly class is difficult, hence becomes another drawback for supervised anomaly detection approach (8,10). They introduced another category of anomaly detection approach; semi-supervised.…”
