This book constitutes the refereed post-conference proceedings of the First International Conference on Pervasive Knowledge and Collective Intelligence on Web and Social Media, PerSOM 2022, which was held in Messina, Italy, in November 2022. The 9 full papers were carefully reviewed and selected from 35 submissions and present findings of research from the fields of pervasive computing, web, and social media to promote ideas and practices about pervasive knowledge and collective intelligence in this fields. The conference targeted a wide variety of topics including new perspectives in social theories, complex networks, data science, knowledge management, web and social media.

This book constitutes the refereed proceedings of the Second EAI International Conference on Pervasive Knowledge and Collective Intelligence on Web and Social Media, PerSOM 2023, which took place in Hyderabad, India, during November 24–25, 2023. The 28 full papers included in the proceedings were carefully reviewed and selected from 70 submissions. They focus on information and Web mining, social network analysis, semantic network analysis, trust, reputation, social control and privacy, information reliability, and Web and content authenticity.

Computational collective intelligence (CCI) is most often understood as a subfield of artificial intelligence (AI) dealing with soft computing methods that enable group decisions to be made or knowledge to be processed among autonomous units acting in distributed environments. The needs for CCI techniques and tools have grown signi- cantly recently as many information systems work in distributed environments and use distributed resources. Web-based systems, social networks and multi-agent systems very often need these tools for working out consistent knowledge states, resolving conflicts and making decisions. Therefore, CCI is of great importance for today’s and future distributed systems. Methodological, theoretical and practical aspects of computational collective int- ligence, such as group decision making, collective action coordination, and knowledge integration, are considered as the form of intelligence that emerges from the collabo- tion and competition of many individuals (artificial and/or natural). The application of multiple computational intelligence technologies such as fuzzy systems, evolutionary computation, neural systems, consensus theory, etc. , can support human and other collective intelligence and create new forms of CCI in natural and/or artificial s- tems.

As social technologies continue to evolve, it is apparent that librarians and their clientele would benefit through participation in the digital social world. While there are benefits to implementing these technologies, many libraries also face challenges in the integration and usage of social media. Social Media Strategies for Dynamic Library Service Development discusses the integration of digital social networking into library practices. Highlighting the advantages and challenges faced by libraries in the application of social media, this publication is a critical reference source for professionals and researchers working within the fields of library and information science, as well as practitioners and executives interested in the utilization of social technologies in relation to knowledge management and organizational development.

This textbook introduces the “Fundamentals of Multimedia”, addressing real issues commonly faced in the workplace. The essential concepts are explained in a practical way to enable students to apply their existing skills to address problems in multimedia. Fully revised and updated, this new edition now includes coverage of such topics as 3D TV, social networks, high-efficiency video compression and conferencing, wireless and mobile networks, and their attendant technologies. Features: presents an overview of the key concepts in multimedia, including color science; reviews lossless and lossy compression methods for image, video and audio data; examines the demands placed by multimedia communications on wired and wireless networks; discusses the impact of social media and cloud computing on information sharing and on multimedia content search and retrieval; includes study exercises at the end of each chapter; provides supplementary resources for both students and instructors at an associated website.
