Book Description :

The book lies at the interface of mathematics, social media analysis, and data science. Its authors aim to introduce a new dynamic modeling approach to the use of partial differential equations for describing information diffusion over online social networks. The eigenvalues and eigenvectors of the Laplacian matrix for the underlying social network are used to find communities (clusters) of online users. Once these clusters are embedded in a Euclidean space, the mathematical models, which are reaction-diffusion equations, are developed based on intuitive social distances between clusters within the Euclidean space. The models are validated with data from major social media such as Twitter. In addition, mathematical analysis of these models is applied, revealing insights into information flow on social media. Two applications with geocoded Twitter data are included in the book: one describing the social movement in Twitter during the Egyptian revolution in 2011 and another predicting influenza prevalence. The new approach advocates a paradigm shift for modeling information diffusion in online social networks and lays the theoretical groundwork for many spatio-temporal modeling problems in the big-data era.

Book Description :

Geosocial Networking has seen an explosion of activity in the past year with the coming of services that allow users to submit information about where they are and share that information with other users. But, because of privacy and security reasons, most of the people on social networking sites like Twitter are unwilling to specify their locations in the profiles. Just like time, location is one of the most important attributes associated with a user. The dissertation presents three novel approaches that rely on supervised and semi-supervised learning algorithms to predict the city level home location of the user purely on the basis of his/her social network. We firstly begin by establishing a relationship between geospatial proximity and friendship. The first approach, Tweethood, describes a fuzzy k -closest neighbor method with variable depth, a supervised learning algorithm, for determining the location. In our second approach, Tweecalization, we improve the previous work and show how this problem can be mapped to a semi-supervised learning problem and apply a label propagation algorithm. The previous approaches have a drawback in that they do not consider geographical migration of users. For our third algorithm, we begin by understanding the social phenomenon of migration and then perform graph partitioning for identifying social groups allowing us to implicitly consider time as a factor for prediction of the user's most current city location. Finally, as an application for location mining, we build TWinner, which focuses on understanding news queries and identifying the intent of the user so as to improve the quality of web search. We perform extensive experiments to show the validity of our systems in terms of both accuracy and running time.

Book Description :

Following the introduction of Myspace, Linkedin and Facebook, social networks have become part of people’s everyday life. New online social networks appear almost daily developed to attract the attention of Internet users. However, design and implementation standards and guidelines are often sacrificed for innovation resulting in unusable social networking platforms destined to be doomed. Within this context, the present book recommends a design and implementation methodology which will allow future social networking platform designers and developers to work in a scientifically systematic and sound manner to reach their goal. The journey begins with the identification of the pursued objective of the social network and the potential participants. The presentation of various methods and techniques to collect the requirements of the intended user group of the social networking platform follows. Best practices, guidelines and standards that will facilitate the conceptual and physical design of the platform are portrayed. An analysis of advantages and limitations for existing implementation platforms and potential implementation techniques is subsequently offered to facilitate the selection of the most appropriate tool for the implementation of the online social networking website. Various representative visualization techniques are examined in order to enhance the visual representation of the social network participants. Various usability evaluation techniques are then presented to aid in the assessment of usability and improvement of the actual user experience. Finally, future trends in the design and use of social networks are presented.

This edited volume addresses the vast challenges of adapting Online Social Media (OSM) to developing research methods and applications. The topics cover generating realistic social network topologies, awareness of user activities, topic and trend generation, estimation of user attributes from their social content, behavior detection, mining social content for common trends, identifying and ranking social content sources, building friend-comprehension tools, and many others. Each of the ten chapters tackle one or more of these issues by proposing new analysis methods or new visualization techniques, or both, for famous OSM applications such as Twitter and Facebook. This collection of contributed chapters address these challenges. Online Social Media has become part of the daily lives of hundreds of millions of users generating an immense amount of 'social content'. Addressing the challenges that stem from this wide adaptation of OSM is what makes this book a valuable contribution to the field of social networks.

Book Description :

"If you want to understand why Wikipedia is changing the world, this book is a must read." –Jimmy Wales, Founder, Wikipedia "This book is a must read for all - social activists, politicians or managers - who have an interest in understanding how our society is morphing." –Professor C.K. Prahalad, #1 Management Guru and author of Competing for the Future Synopsis The rise of social networks like Facebook, MySpace and Bebo is changing the way we see ourselves, how we interact with each other, how we work and how we do business on a daily basis. Throwing Sheep in the Boardroom explores the powerful forces driving the social networking revolution, the impact of these profound changes, and the far reaching consequences of social networking. Detailing the way social networks affects both individuals and societies as a whole, the book offers a detailed focus on the ways social networking affects the world of business and work. The generation entering the workforce today - and entering boardrooms everywhere - is fully engaged with social networking and its uses. Rather than feeling threatened and paranoid, today's business leaders need to understand this phenomenon, accept that it won't go away, and embrace its power in the world of business. Excerpts from Throwing Sheep in the Boardroom: "Your next CEO’s most impressive job credential might be status as an online gladiator, honing valuable leadership skills mercilessly slaying mortal enemies on World of Warcraft. Why not, the skills necessary to hack your way to the top levels of virtual games – especially a killer instinct – are excellent pre-requisites for managing complex organisations." "Many senior managers mistakenly believe Enterprise 2.0 is a product, like the latest Microsoft office suite. They don’t realise that Enterprise 2.0 is not a cost centre, but a “state of mind” – a revolutionary new way of managing companies and conducting business. Web 2.0 tools have no regard for “organisational boundaries, hierarchies, or job titles”. Try telling a senior executive that, henceforth, there will be no job titles, reporting lines, and organisational boundaries in the company – and watch the reaction closely." "When someone calls a meeting, he or she is asserting authority over those who are invited to attend. Meetings are exclusive and closed. In most corporations, who gets invited to a meeting – and who does not – sends a signal about who’s ‘in the loop’. Meetings are a form of social grooming inside organisations. Meetings impose vertical authority. They establish status hierarchies. The Enterprise 2.0 model is feared in corporations because it threatens status hierarchies." "Harnessing the dynamism of horizontal networks, Web 2.0 social media are bypassing institutional forms of social organisation and directly empowering people. This book has attempted to tell that story with illustrations, which, we hope, have offered intriguing and instructive insights into the powerful transformations we described. What has interested us most, indeed, is the transformative impact – or “e-ruptions” – of Web 2.0 social media on the three dynamics that gave this book its structure: identity, status and power."

The prevalence of online social networking sites offers the possibility of mining for necessary information. However, existing influence maximization algorithms and newly proposed influence diffusion models do not distinguish between seed nodes (or pilot users) and nonseed nodes and assume all nodes are cooperative in propagating influence. This thesis investigates models and heuristics for noncooperative information diffusion in online social networks. It consists of three parts: tragedy of the commons in online social search (OSS), influence maximization in noncooperative social networks under the linear threshold model (LTM), and influence maximization in noncooperative social networks under the independent cascade model (ICM). Firstly, the tragedy of the commons problem in OSS is considered. I propose an analytical model that captures the behavior of OSS nodes, and, from a gaming-strategy point of view, analyze various strategies an individual node can utilize to allocate its awareness capacity. Based on this I derive the Pareto inefficiency in terms of the system cost. An incentive scheme which can lead selfish nodes to the "social optimal" state of the whole system is also proposed. Extensive simulations show that the strategy with our proposed incentive mechanism outperforms other strategies in terms of the system cost and the search success rate. The second part of the thesis presents the first detailed analysis of influence maximization in noncooperative social networks under the LTM. The influence propagation process is structured into two stages, namely, seed node selection and influence diffusion. In the former, I introduce a generalized maximum-flow-based analytical framework to model the noncooperative behavior of individual users and develop a new seed node selection strategy. In the latter, I propose a game-theoretic model to characterize the behavior of noncooperative nodes and design a Vickrey-Clarke-Groves-like (VCG-like) scheme to incentivise cooperation. Then I study the budget allocation problem between the two stages, and show that a marketer can utilize the two proposed strategies to tackle noncooperation intelligently. The proposed schemes are evaluated on large coauthorship networks, and the results show that the proposed seed node selection scheme is very robust to noncooperation and the VCG-like scheme can effectively stimulate a node to become cooperative. Finally, I study the influence maximization problem in noncooperative social networks under the ICM using the same two-stage framework originally proposed for LTM. For the seed selection stage, a modified hierarchy-based seed node selection strategy which can take node noncooperation into consideration is introduced. The VCG-like incentive scheme designed for the influence diffusion stage under LTM can also be utilized for ICM in a similar manner. Then I also study the budget allocation problem between the two stages. The evaluation results show that the performance of the hierarchy-based seed node selection scheme is satisfactory in a noncooperative social network and the VCG-like scheme can effectively encourage node cooperation.
