Social Networks and Trust discusses two possible explanations for the emergence of trust via social networks. If network members can sanction untrustworthiness of actors, these actors may refrain from acting in an untrustworthy manner. Moreover, if actors are informed regularly about trustworthy behavior of others, trust will grow among these actors. A unique combination of formal model building and empirical methodology is used to derive and test hypotheses about the effects of networks on trust. The models combine elements from game theory, which is mainly used in economics, and social network analysis, which is mainly used in sociology. The hypotheses are tested (1) by analyzing contracts in information technology transactions from a survey on small and medium-sized enterprises and (2) by studying judgments of subjects in a vignette experiment related to hypothetical transactions with a used-car dealer.
Security and Trust in Online Social Networks by Barbara Carminati,Elena Ferrari,Marco Viviani Pdf
The enormous success and diffusion that online social networks (OSNs) are encountering nowadays is vastly apparent. Users' social interactions now occur using online social media as communication channels; personal information and activities are easily exchanged both for recreational and business purposes in order to obtain social or economic advantages. In this scenario, OSNs are considered critical applications with respect to the security of users and their resources, for their characteristics alone: the large amount of personal information they manage, big economic upturn connected to their commercial use, strict interconnection among users and resources characterizing them, as well as user attitude to easily share private data and activities with strangers. In this book, we discuss three main research topics connected to security in online social networks: (i) trust management, because trust can be intended as a measure of the perception of security (in terms of risks/benefits) that users in an OSN have with respect to other (unknown/little-known) parties; (ii) controlled information sharing, because in OSNs, where personal information is not only connected to user profiles, but spans across users' social activities and interactions, users must be provided with the possibility to directly control information flows; and (iii) identity management, because OSNs are subjected more and more to malicious attacks that, with respect to traditional ones, have the advantage of being more effective by leveraging the social network as a new medium for reaching victims. For each of these research topics, in this book we provide both theoretical concepts as well as an overview of the main solutions that commercial/non-commercial actors have proposed over the years. We also discuss some of the most promising research directions in these fields.
Roles, Trust, and Reputation in Social Media Knowledge Markets by Elisa Bertino,Sorin Adam Matei Pdf
Knowledge and expertise, especially of the kind that can shape public opinion, have been traditionally the domain of individuals holding degrees awarded by higher learning institutions or occupying formal positions in notable organizations. Expertise is validated by reputations established in an institutionalized marketplace of ideas with a limited number of “available seats” and a stringent process of selection and retention of names, ideas, topics and facts of interest. However, the social media revolution, which has enabled over two billion Internet users not only to consume, but also to produce information and knowledge, has created a secondary and very active informal marketplace of ideas and knowledge. Anchored by platforms like Wikipedia, YouTube, Facebook and Twitter, this informal marketplace has low barriers to entry and has become a gigantic and potentially questionable, knowledge resource for the public at large. Roles, Trust and Reputation in Social Media Knowledge Markets will discuss some of the emerging trends in defining, measuring and operationalizing reputation as a new and essential component of the knowledge that is generated and consumed online. The book will propose a future research agenda related to these issues. The ultimate goal of research agenda being to shape the next generation of theoretical and analytic strategies needed for understanding how knowledge markets are influenced by social interactions and reputations built around functional roles. The authors, including leading scholars and young innovators, will share with the readers some of the main lessons they have learned from their own work in these areas and will discuss the issues, topics and sub-areas that they find under-studied or that promise the greatest intellectual payoff in the future. The discussion will be placed in the context of social network analysis and “big data” research. Roles, Trust and Reputation in Social Media Knowledge Markets exposes issues that have not been satisfactorily dealt with in the current literature, as the research agenda in reputation and authorship is still emerging. In a broader sense, the volume aims to change the way in which knowledge generation in social media spaces is understood and utilized. The tools, theories and methodologies proposed by the contributors offer concrete avenues for developing the next generation of research strategies and applications that will help: tomorrow’s information consumers make smarter choices, developers to create new tools and researchers to launch new research programs.
Social Media and Trust by Joanna Paliszkiewicz,Alex Koohang Pdf
Researchers and practitioners alike often overlook the vital relationship between trust and social media. ... Authors Joanna Paliszkiewicz and Alex Koohang charted a course to explore this abyss with a view to answering the question how does trust influence the use of social media. [i]Dr. John P. Girard, Peyton Anderson Endowed Chair in Information Technology, Middle Georgia State University[/i] The authors have done an excellent job in explaining how trust plays a significant role in social media. The book begins with a thorough overview of social media to its applications in learning, business, and an analysis of social media and trust. The second part of the book uses data from four different countries to answer multiple valid and vital research questions dealing with social media and trust, including an instrument that measures trust variables. This book presents some meaningful work on how the integration of social media and trust can best be developed. The authors apply their backgrounds in information technology, knowledge management, trust, and business to generate some provocative and instructive guidance to the readers on how to best leverage knowledge internally and externally to meet the organizational strategic goals.

Networks, Trust and Social Capital by Sokratis M. Koniordos Pdf
The concepts of social networks, social capital and trust play an increasingly central role in the social sciences. They have become indispensable conceptual tools for the analysis of post-industrial/late-modern societies, which are characterized by such features as the relative decline of formal hierarchies, the development of flexible social arrangements in the sphere of production and the extreme mobility of capital. This is the first book to study the interrelationships between these important concepts both theoretically and empirically. Drawing on empirical investigations from a range of diverse European social contexts, the contributors develop an economic sociology that builds on and extends established theoretical perspectives. The book opens with an introduction to the theoretical ideas: relating social capital to reciprocity, trust and social networks in line with current debates. The authors go on to discuss the concept of social embededdness, addressing the economic effects of social capital by examining the network and trust foundations of labour markets and investigating the structural limits of trusting networks. They conclude with an exploration of the impact of networking and the functioning of trust and social capital on the economic arrangements and performance of nascent capitalist economies in post-Communist Europe. This thematically unified collection by a team of distinguished contributors from across Europe provides an innovative and distinctive contribution to an expanding area of research.
Migration-Trust Networks by Nadia Yamel Flores-Yeffal Pdf
In an important new application of sociological theories, Nadia Y. Flores-Yeffal offers fresh insights into the ways in which social networks function among immigrants who arrive in the United States from Mexico without legal documentation. She asks and examines important questions about the commonalities and differences in networks for this group compared with other immigrants, and she identifies “trust” as a major component of networking among those who have little if any legal protection. Revealing the complexities behind social networks of international migration, Migration-Trust Networks: Social Cohesion in Mexican US-Bound Emigration provides an empirical and theoretical analysis of how social networks of international migration operate in the transnational context. Further, the book clarifies how networking creates chain migration effects observable throughout history. Flores-Yeffal’s study extends existing social network theories, providing a more detailed description of the social micro- and macrodynamics underlying the development and expansion of social networks used by undocumented Mexicans to migrate and integrate within the United States, with trust relationships as the basis of those networks. In addition, it incorporates a transnational approach in which the migrant’s place of origin, whether rural or urban, becomes an important variable. Migration-Trust Networks encapsulates the new realities of undocumented migration from Latin America and contributes to the academic discourse on international migration, advancing the study of social networks of migration and of social networks in general.
Computing with Social Trust by Jennifer Golbeck Pdf
This book has evolved out of roughly ve years of working on computing with social trust. In the beginning, getting people to accept that social networks and the relationships in them could be the basis for interesting, relevant, and exciting c- puter science was a struggle. Today, social networking and social computing have become hot topics, and those of us doing research in this space are nally nding a wealth of opportunities to share our work and to collaborate with others. This book is a collection of chapters that cover all the major areas of research in this space. I hope it will serve as a guide to students and researchers who want a strong introduction to work in the eld, and as encouragement and direction for those who are considering bringing their own techniques to bear on some of these problems. It has been an honor and privilege to work with these authors for whom I have so much respect and admiration. Thanks to all of them for their outstanding work, which speaks for itself, and for patiently enduringall my emails. Thanks, as always, to Jim Hendler for his constant support. Cai Ziegler has been particularly helpful, both as a collaborator, and in the early stages of development for this book. My appreciation also goes to Beverley Ford, Rebecca Mowat and everyone at Springer who helped with publication of this work.

Trust in Social Media by Jiliang Tang,Huan Liu Pdf
Social media greatly enables people to participate in online activities and shatters the barrier for online users to create and share information at any place at any time. However, the explosion of user-generated content poses novel challenges for online users to find relevant information, or, in other words, exacerbates the information overload problem. On the other hand, the quality of user-generated content can vary dramatically from excellence to abuse or spam, resulting in a problem of information credibility. The study and understanding of trust can lead to an effective approach to addressing both information overload and credibility problems. Trust refers to a relationship between a trustor (the subject that trusts a target entity) and a trustee (the entity that is trusted). In the context of social media, trust provides evidence about with whom we can trust to share information and from whom we can accept information without additional verification. With trust, we make the mental shortcut by directly seeking information from trustees or trusted entities, which serves a two-fold purpose: without being overwhelmed by excessive information (i.e., mitigated information overload) and with credible information due to the trust placed on the information provider (i.e., increased information credibility). Therefore, trust is crucial in helping social media users collect relevant and reliable information, and trust in social media is a research topic of increasing importance and of practical significance. This book takes a computational perspective to offer an overview of characteristics and elements of trust and illuminate a wide range of computational tasks of trust. It introduces basic concepts, deliberates challenges and opportunities, reviews state-of-the-art algorithms, and elaborates effective evaluation methods in the trust study. In particular, we illustrate properties and representation models of trust, elucidate trust prediction with representative algorithms, and demonstrate real-world applications where trust is explicitly used. As a new dimension of the trust study, we discuss the concept of distrust and its roles in trust computing.

Knowledge Management, Trust and Communication in the Era of Social Media by Joanna Paliszkiewicz Pdf
The article entitled "Selected Aspects of Evaluating Knowledge Management Quality in Contemporary Enterprises" broadens the understanding of knowledge management and estimates select aspects of knowledge management quality evaluations in modern enterprises from theoretical and practical perspectives. The seventh article aims to present the results of pilot studies on the four largest Information Communication Technology (ICT) companies' involvement in promoting the Sustainable Development Goals (SDGs) through social media. Studies examine which communication strategy is used by companies in social media. The primary purpose of the eighth article is to present the relationship between trust and knowledge sharing, taking into account the importance of this issue in the efficiency of doing business. The results showed that trust is vital in sharing knowledge and essential in achieving a high-performance efficiency level. The ninth article presents the impact of social media on consumer choices in tourism and tourist products' specificity. The study's main purpose was to indicate the most commonly used social media in selecting a tourist destination and implementing Generation Y's journey. The 10th article aims to identify the most critical purposes of using social media by responding to women's attitudes according to age and their respective countries' economic development. The research was done through an online survey in 2017–2018, followed by an analysis of eight countries' results. The article entitled "Integrated Question-Answering System for Natural Disaster Domains Based on Social Media Messages Posted at the Time of Disaster" presents the framework of a question-answering system that was developed using a Twitter dataset containing more than 9 million tweets compiled during the Osaka North Earthquake that occurred on 18 June 2018. The authors also study the structure of the questions posed and develop methods for classifying them into particular categories to find answers from the dataset using an ontology, word similarity, keyword frequency, and natural language processing. The book provides a theoretical and practical background related to trust, knowledge management, and communication in the era of social media. The editor believes that the collection of articles can be relevant to professionals, researchers, and students' needs. The authors try to diagnose the situation and show the new challenges and future directions in this area.
