Social circles arised out of a need to organize the contacts in personal networks, within the current social networking services. The automatic detection of these social circles still remains an understudied problem, and is currently attracting a growing interest in the research community. This task is related to the classical problem of community detection in networks, albeit it presents some peculiarities, like overlap and hierarchical inclusion of circles. The usual community detection...

Virality of online content on social networking websites is an important but esoteric phenomenon often studied infields like marketing, psychology and data mining. In this paper we study viral images from a computer vision perspective. We introduce three new image datasets from Reddit and define a virality score using Reddit metadata.We train classifiers with state-of-the-art image features to predict virality of individual images, relative virality in pairs of images, and the dominant topic of...

Studies have shown that each person is more inclined to enjoy a group activity when 1) she is interested in the activity, and 2) many friends with the same interest join it as well. Nevertheless, even with the interest and social tightness information available in online social networks, nowadays many social group activities still need to be coordinated manually. In this paper, therefore, we first formulate a new problem, named Participant Selection for Group Activity (PSGA), to decide the...

We present a micro-architectural side-channel attack that runs entirely in the browser. In contrast to previous work in this genre, our attack does not require the attacker to install software on the victim's machine; to facilitate the attack, the victim needs only to browse to an untrusted webpage that contains attacker-controlled content. This makes our attack model highly scalable, and extremely relevant and practical to today's Web, as most desktop browsers currently used to access the...

Nothing throws leadership into starker relief than a crisis, as Hurricane Katrina and the Great East Japan earthquake both demonstrated. Now more than ever, the ripple effects from a crisis spread far beyond its epicenter, often in unexpected ways. At the same time, faith in authority has eroded: trust in the U.S. Federal Governments ability to handle domestic problems, for example, has been declining for the past decade.1 Add the challenge of managing digital media and its rapid information...

In 2004, General James Hoss Cartwright blazed a new trail for the use of social media in the military when he introduced the concept of a blog system to tie together all of the United States Strategic Command (USSTRATCOM) headquarters. After the military's first use of chat in command and control using basic mIRC chat back in the 1990s, the inclusion of social media in military networks had not gained significant traction. Although some type of social media was eventually included in the...

Sociologists, economists, and network scientists concur that the entrepreneurs network is critical to success but have consistently struggled with developing models that are measurable or quantifiable. Well-known research on this subject tends to focus on the entrepreneurs social network (Greve and Salaff, 2003, Witt, 1978) and utilizes the Name Generator approach (McAllister and Fischer, 1978) to develop the social network model. This method maps an ego-centered network and assembles an...

Many real networks that are collected or inferred from data are incomplete due to missing edges. Missing edges can be inherent to the dataset (Facebook friend links will never be complete) or the result of sampling (one may only have access to a portion of the data). The consequence is that downstream analyses that consume the network will often yield less accurate results than if the edges were complete. Community detection algorithms, in particular, often suffer when critical intra-community...

The impact of the internet and social media tools on authoritarian regimes and would be revolutionaries remains a hotly debated topic even after a decade of widespread internet access. This paper argues that dissidents' use of the Internet and social media tools undermines authoritarian power, however the state will likely retain the advantage. First, to frame the argument, it is useful to examine past information communication technologies (ICT) by exploring their nature, uses, and impacts on...

We show that this method can be used to group email addresses that indicate real communication between users and those that do not. Furthermore, in the case where addresses do represent communication between...

Technological advances and social media are both amoral; in and of itself, there is no good social media or bad social media. Like the rest of the world, extremist organizations have discovered social media and are not going to stop using it anytime soon.

Open access in cyberspace forces countries into a paradoxical position of how to grant access to the internet yet maintain control of the social media...

Because forming a connection is known as following in social networks such as Twitter, we refer to this as the follow back problem.

The agents goal is to get the target to follow him, and he is allowed to interact with the target and the targets friends. To...
