The last few years have seen an exponential increase in the amount of multimedia content that is available online thanks to collaborative-online communities such as Flickr, You Tube etc. As opposed to "pure" social networking services these collaborative-online communities not only allow users to create new social links (e. g. add other users to their friend or contact list) but also allow users to contribute multimedia content and engage in content-driven interactions (called user-to-content interactions). A good example of this can be seen in Flickr, in general and Flickr Group in particular where users can comment on or "like" an image contributed by another user. This paper looks at the task of predicting the formation of such user-to-content links in Flickr Groups. More specifically, what is the chance that a user will comment/like an image contributed by another user?. Our proposed method for predicting user-to-content links takes into account both community effect and content effect. Our results on real-world Flickr Group data reveals that the proposed method shows good performance for the user-to-content link prediction task.

Social networks can facilitate creative dialogue between participants whose geographical, cultural and social circumstances normally does not allow for such exchanges. In this paper, we present a case study of a collaborative process in which 19 participants from around the world created the multimedia, multi-language poem, "Our Digital Tapestry", on the Facebook social network. We identify and discuss the affordances of this platform with respect to support for play, control, diversity, inclusion of hypertext and multimedia, communication and relationship exploration. We also identify several restrictions of the medium that affected the project. Copyright 2012 ACM.

This study proposes a phone-based system to detect the gait anomalies of a person waking under the influence of alcohol. This phone-based system can sense a person's alcohol usage and record the location/time context. This data can help identify problem drinking behaviors, such as drinking before work or before driving. Copyright 2012 ACM.
The present work is concerned with a particular type of online collaborative engagements, namely the management of e-Health campaigns and online intervention studies. In order to establish the baseline, the paper crit...

From both technical and social viewpoints there is great value in services that require devices (and therefore people) to be co-located. The very act of co-location brings with it entirely new dynamics and collaboration;furthermore, devices in coalition can render services and provide experiences that a single device might not be able to. In this paper we describe the motivation, design, and uses of high experience coalition-based services and outline how such services could be architecture on both the server and client sides. Extensive use of video transcoding and region-of-interest techniques - to segment and stream only portions of video frames - makes delivering experiences like "social cinema" across several co-located devices feasible. On the client side smartphone-based interactive coalition setup and control is very viable. In this paper we explore and document our functional architecture and take a closer look at the similarities and differences between OnLive and our proposed architecture and services. The rising prominence of hire-solution LED devices together with services such as OnLive make coalition services technically viable, desirable, and worthy of both industrial and academic investigation alike.

The registration process is open for IEEE WCNC 2012 to be held on April 1 4, 2012, at the Palais des Congrès Porte Maillot in Paris, France. Devoted to the entire range of wireless communications and networking technologies, the program of IEEE WCNC 2012 will include 620 technical papers distributed in four tracks, nine tutorials, seven workshops, four keynotes, and eight business panels. All these events will explore topics such as latest advances in digital cellular, PCS, multimedia and wireless networking technologies, and channel modeling, radio resource management and emerging mobile applications. Specific areas to be discussed include 'Mobile Cloud computing', 'Heterogeneous Cellular Networks', 'Machine-to-Machine in Smart Grids and Smart Cities', 'Future Green Communications', 'Wireless Vehicular Communications and Networks', 'Cooperation and Coordination Over Cellular Networks', 'Internet of Things Enabling Technologies', and 'Wireless Cloud and White Space Oriented Networks'.
