Doctoral Thesis / Dissertation from the year 2011 in the subject Computer Science - Internet, New Technologies, grade: 1,0, Karlsruhe Institute of Technology (KIT), language: English, abstract: Social Web applications have emerged as powerful applications for Internet users allowing them to freely contribute to the Web content, organize and share information, and utilize the collective knowledge of others for discovering new topics, resources and new friends. While social Web applications such as social tagging systems have many benefits, they also present several challenges due to their open and adaptive nature. The amount of user generated data can be extremely large and since there is not any controlled vocabulary or hierarchy, it can be very difficult for users to find the information that is of their interest. In addition, attackers may attempt to distort the system's adaptive behavior by inserting erroneous or misleading annotations, thus altering the way in which information is presented to legitimate users. This thesis utilizes data mining and machine learning techniques to address these problems. In particular, we design and develop recommender systems to aid the user in contributing to the Social Semantic Web. In addition, we study intelligent techniques to combat attacks against social tagging systems. In our work, we first propose a framework that maps domain properties to recommendation technologies. This framework provides a systematic approach to find the appropriate recommendation technology for addressing a given problem in a specific domain. Second, we improve existing graph-based approaches for personalized tag recommendation in folksonomies. Third, we develop machine learning algorithms for recommendation of semantic relations to support continuous ontology development in a social semanticWeb environment. Finally, we introduce a framework to analyze different types of potential attacks against social tagging systems and evaluate their impact on t

In the next twenty years, the convergence of robotics, informatics, nano-bio-technologies, genetics, information technologies, and cognitive sciences will have a significant impact on society. This convergence will lead to a revolution in the way that science, health, energy, resources, production, consumption and environment are conceptualised. However, these technologies will also pose new and specific challenges in terms of sustainability, ethics, and even expectations of the future. Indeed, today, the word “future” is often associated with pessimism and fear, much more than it was in the past. In order to face all these technological, ethical and cultural challenges, governments, industries and societies will need a robust cognitive framework, in order to grasp the complex dimensions of the technological convergence in progress, and must rapidly develop effective strategies to face the situations that will, unavoidably, take place. This book provides, through systemic and complexity theories, some of the theoretical tools necessary to tackle the opportunities and risks of the future.

Artificial intelligence (Al) is set to revolutionise all aspects of modern life. Africa is boarding this train at its own pace and in its own way to tackle its unique challenges. This White Paper, the result of the 7th edition of the African Competitive Intelligence Days (JAIE2024), reports on this dynamic and explores the potential of Al to contribute to economic growth and the improvement of public services in Africa. Twenty-one authors present a detailed overview of the challenges and opportunities related to Al, analyse its areas of application, and formulate concrete recommendations for the emergence of a controlled Al on the continent.

Online social networks have already become a bridge connecting our physical daily life with the (web-based) information space. This connection produces a huge volume of data, not only about the information itself, but also about user behavior. The ubiquity of the social Web and the wealth of social data offer us unprecedented opportunities for studying the interaction patterns among users so as to understand the dynamic mechanisms underlying different networks, something that was previously difficult to explore due to the lack of available data. In this book, we present the architecture of the research for social network mining, from a microscopic point of view. We focus on investigating several key issues in social networks. Specifically, we begin with analytics of social interactions between users. The first kinds of questions we try to answer are: What are the fundamental factors that form the different categories of social ties? How have reciprocal relationships been developed from parasocial relationships? How do connected users further form groups? Another theme addressed in this book is the study of social influence. Social influence occurs when one's opinions, emotions, or behaviors are affected by others, intentionally or unintentionally. Considerable research has been conducted to verify the existence of social influence in various networks. However, few literature studies address how to quantify the strength of influence between users from different aspects. In Chapter 4 and in [138], we have studied how to model and predict user behaviors. One fundamental problem is distinguishing the effects of different social factors such as social influence, homophily, and individual's characteristics. We introduce a probabilistic model to address this problem. Finally, we use an academic social network, ArnetMiner, as an example to demonstrate how we apply the introduced technologies for mining real social networks. In this system, we try to mine knowledge from both the informative (publication) network and the social (collaboration) network, and to understand the interaction mechanisms between the two networks. The system has been in operation since 2006 and has already attracted millions of users from more than 220 countries/regions.

Social welfare is riddled with ingrained problems that have already defeated all standard approaches, and reform calls for counterintuitive action. Digital Social Innovation (DSI) is primarily about promoting grassroots initiatives to address localized societal problems, and is not normally talked about in relation to welfare reform, but perhaps social innovation initiatives, with their localized and case-based approach, could help to solve the enormous structural problems faced by our welfare democracies today. This book addresses the potential and implications of DSI for the reform of the European welfare state. The 14 papers collected here focus on key issues, such as the nature of social innovation and its effects; scaling up to address structural problems and make systemic change; new social risks and challenges; the role of digital thinking and emerging technologies; public governance approaches; tolerance of institutions; integrating innovation in the welfare system; and the empowerment of marginalized citizens. These topics are examined from an integrated and multi-disciplinary perspective, taking into consideration not only current EU debate on policy trends for social protection, but also the nature of digital transformation and its effects on social change. The book also highlights barriers to adoption, as well as the potential limitations and failures of this emerging approach. Digital social innovation is an emerging discipline that deserves more attention from policy makers and more resources from government. Drawing on welfare studies, political science, sociology, psychology, law and computer science, this book will be of interest to researchers, practitioners and policy makers alike.
