Today web portals play an increasingly important role in health care allowing information seekers to learn about diseases and treatments, and to administrate their care. Therefore, it is important that the portals are able to support this process as well as possible. In this paper, we study the search logs of a public Swedish health portal to address the(More)
Community detection algorithms are widely used to study the structural properties of real-world networks. In this paper, we experimentally evaluate the qualitative performance of several community detection algorithms using large-scale email networks. The email networks were generated from real email traffic and contain both legitimate email (ham) and(More)
Identifying unsolicited email based on their network-level behavior rather than their content have received huge interest. In this study, we investigate the social network properties of large-scale <i>email networks</i> generated from real email traffic to reveal the properties that are indicative of spam as opposed to the expected legitimate behavior. By(More)
We have collected several large-scale datasets in a number of passive measurement projects on an Internet backbone link belonging to a national university network. The datasets have been used in different studies such as in general classification and characterization of properties of Internet traffic, in network security projects detecting and classifying(More)
As a result of shrinking device dimensions, the occurrence of transient errors is increasing. This causes system reliability to be reduced. Thus, fault-tolerant methods are becoming increasingly important, particularly in safety-critical applications. In this paper a novel fault-tolerant method is proposed through combining time redundancy with information(More)
One of the widely studied structural properties of social and information networks is their community structure, and a vast variety of community detection algorithms have been proposed in the literature. Expansion of a seed node into a community is one of the most successful methods for local community detection, especially when the global structure of the(More)
In this paper we present a large-scale measurement study and analysis of e-mail traffic collected on an Internet backbone link. To the best of our knowledge this is one of the largest studies of network-wide behavior of e-mail traffic. We consider e-mail networks connecting senders and receivers that have communicated via e-mail, capturing their social(More)

In this paper, we study the problem of identifying misbehaving network communications using community detection algorithms. Recently, it was shown that identifying the communications that do not respect community boundaries is a promising approach for network intrusion detection. However, it was also shown that traditional community detection algorithms are(More)
