It is my great honour to welcome you to CIKM 2019, the 28th ACM International Conference on Information and Knowledge Management, will be held in Beijing, China from the 3rd to the 7th of November 2019. Beijing, the capital city of China, is a major historical and cultural centre, as well as China's largest science and technology hub. CIKM is an annual conference in the computer science research field. Since it was first held in the United States in 1992, 27 conferences have been held in 8 countries around the world. The research areas it primarily focuses on include database management, information retrieval, and knowledge management. It has been evolving into a major conference in these research areas. Our theme this year is "AI for future life". Since the term "artificial intelligence" was first proposed by John McCarthy in 1955, artificial intelligence has been evolving for more than half a century. It is gaining greater significance in our daily lives, and the importance of scientific research in the area is becoming increasingly prominent. We are proud to present four distinguished keynote speakers to CIKM 2019 attendees: Steve Maybank, Jiawei Han, Jian Pei and Jianping Shi. We are also honored to have about ten spectacular industry talks in this year's conference. To allow the participants to better understand the most cutting-edge work in today's research field, we will arrange 9 tutorials, 9 workshops, and 26 demos. World renowned experts from academia and industry have been invited to give keynote speeches to showcase and disseminate the latest research outcome in related research fields. We are honored to announce that this conference has received 1676 submissions. All these submissions were assigned to qualified reviewers and area chairs for review and acceptance. Reviewers and area chairs were selected by Program Committee Chairs through checking their research fields and publications in recent years to avoid conflict with their work throughout the review process. Finally, 202 long papers, 107 short papers and 37 applied research papers were accepted. The number of long, short and applied research papers account for 21% of the total number of accepted papers. The proceedings of CIKM 2019 will be published by ACM.

This book explains how to use a data-driven approach to design strategies for social media content delivery. It first introduces readers to how social information can be effectively gathered for big data analysis, which provides content delivery intelligence. Secondly, the book describes data-driven models to capture information diffusion in online social networks and social media content propagation and popularity, before presenting prediction models for social media content delivery. By addressing the resource allocation and content replication aspects of social media content delivery, the book presents the latest data-driven strategies. In closing, it outlines a number of potential research directions regarding social media content delivery.

This brief presents new architecture and strategies for distribution of social video content. A primary framework for socially-aware video delivery and a thorough overview of the possible approaches is provided. The book identifies the unique characteristics of socially-aware video access and social content propagation, revealing the design and integration of individual modules that are aimed at enhancing user experience in the social network context. The change in video content generation, propagation, and consumption for online social networks, has significantly challenged the traditional video delivery paradigm. Given the massive amount of user-generated content shared in online social networks, users are now engaged as active participants in the social ecosystem rather than as passive receivers of media content. This revolution is being driven further by the deep penetration of 3G/4G wireless networks and smart mobile devices that are seamlessly integrated with online social networking and media-sharing services. Despite increasingly abundant bandwidth and computational resources, the ever-increasing volume of data created by user-generated video content--along with the boundless coverage of socialized sharing--presents unprecedented challenges. .
