The book "Ubiquitous Social Media Analysis" offers a comprehensive collection of research findings that have emerged from international workshops on the topics of Mining Ubiquitous and Social Environments and Modeling Social Media. The contributions have been carefully selected and revised to present the latest developments and insights in the field of social media analysis and its impact on communities and social interactions. The eight included articles cover a wide range of topics organized into three main categories: the structure of communities in social media, the modeling of ubiquitous environments, and the dynamics of social interactions and their influence. This academic book is aimed at researchers, practitioners, and students interested in the technical and social aspects of media analysis.
