Book excerpt: Applications have transformed the collaboration environment from a mere document collection into a highly interconnected social space. These systems interoperate within a social and organizational context that drives their everyday use and provides a rich context for understanding the role of nodes that represent both people and abstract concepts. Techno-Social Systems for Modern Economical and Governmental Infrastructures provides emerging research exploring the theoretical and practical aspects of mining technological and social systems for the creation of scalable methods, systems, and applications within economic and government disciplines. Featuring coverage on a broad range of topics such as analysis models, data navigation, and empirical sociology, this book is ideally designed for professionals, researchers, executives, managers, and developers seeking current research on the interconnecting roles of technology and social space.
