This handbook systematically introduces readers to the key concepts, substantive topics, central methods and prime debates.

The Encyclopedia of Social Media and Politics explores how the rise of social media is altering politics both in the United States and in key moments, movements, and places around the world. Its scope encompasses the disruptive technologies and activities that are changing basic patterns in American politics and the amazing transformations that social media use is rendering in other political systems heretofore resistant to democratization and change. In a time when social media are revolutionizing and galvanizing politics in the United States and around the world, this encyclopedia is a must-have reference. It reflects the changing landscape of politics where old modes and methods of political communication from elites to the masses (top down) and from the masses to elites (bottom up) are being displaced rapidly by social media, and where activists are building new movements and protests using social media to alter mainstream political agendas. Key Features This three-volume A-to-Z encyclopedia set includes 600 short essays on high-interest topics that explore social media’s impact on politics, such as “Activists and Activism,” “Issues and Social Media,” “Politics and Social Media,” and “Popular Uprisings and Protest.” A stellar array of world renowned scholars have written entries in a clear and accessible style that invites readers to explore and reflect on the use of social media by political candidates in this country, as well as the use of social media in protests overseas Unique to this book is a detailed appendix with material unavailable anywhere else tracking and illustrating social media usage by U.S. Senators and Congressmen. This encyclopedia set is a must-have general, non-technical resource for students and researchers who seek to understand how the changes in social networking through social media are affecting politics, both in the United States and in selected countries or regions around the world.

The Encyclopedia of Social Network Analysis and Mining (ESNAM) is the first major reference work to integrate fundamental concepts and research directions in the areas of social networks and applications to data mining. The second edition of ESNAM is a truly outstanding reference appealing to researchers, practitioners, instructors and students (both undergraduate and graduate), as well as the general public. This updated reference integrates all basics concepts and research efforts under one umbrella. Coverage has been expanded to include new emerging topics such as crowdsourcing, opinion mining, and sentiment analysis. Revised content of existing material keeps the encyclopedia current. The second edition is intended for college students as well as public and academic libraries. It is anticipated to continue to stimulate more awareness of social network applications and research efforts. The advent of electronic communication, and in particular on-line communities, have created social networks of hitherto unimaginable sizes. Reflecting the interdisciplinary nature of this unique field, the essential contributions of diverse disciplines, from computer science, mathematics, and statistics to sociology and behavioral science, are described among the 300 authoritative yet highly readable entries. Students will find a world of information and insight behind the familiar façade of the social networks in which they participate. Researchers and practitioners will benefit from a comprehensive perspective on the methodologies for analysis of constructed networks, and the data mining and machine learning techniques that have proved attractive for sophisticated knowledge discovery in complex applications. Also addressed is the application of social network methodologies to other domains, such as web networks and biological networks.

Social networks, or groupings of individuals tied by one or more specific types of interests or interdependencies ranging from likes and dislikes, or disease transmission to the "old boy" network or overlapping circles of friends, have been in existence for longer than services such as Facebook or YouTube; analysis of these networks emphasizes the relationships within the network . This reference resource offers comprehensive coverage of the theory and research within the social sciences that has sprung from the analysis of such groupings, with accompanying definitions, measures, and research. Featuring approximately 350 signed entries, along with approximately 40 media clips, organized alphabetically and offering cross-references and suggestions for further readings, this encyclopedia opens with a thematic Reader's Guide in the front that groups related entries by topics. A Chronology offers the reader historical perspective on the study of social networks. This two-volume reference work is a must-have resource for libraries serving researchers interested in the various fields related to social networks.
