This book delves into the patterns of knowledge sharing on social media platforms, the unique structural features of knowledge domains, the driving forces behind knowledge construction, and the technical means to make knowledge more accessible. Aligned with the broader goals of the New Humanities in the social sciences, this book draws upon communication theory perspectives, leverages information science computational technologies, and employs complex network analysis frameworks to tackle contemporary challenges in communication studies. In essence, this research aims to explore how internet-based knowledge dissemination can enhance the efficiency of sharing knowledge, broaden access to knowledge, and examine how information technology can potentially benefit a wide range of societal groups.
