Welcome to the 13th International Conference on Ubiquitous Information Management and Communication (IMCOM) 2019. This year venue perfectly matches the diversity of this conference by presenting its own rich diversity in picturesque scenery, history and culture. The IMCOM 2019 aims to provide a platform for promoting new visionary approaches and interdisciplinary researches. New evolving technology and novel ideas on the horizon, in the areas of information management, communication technologies and their implications for social interaction, lays the firm foundation of the conference. The conference has served as the most vital platforms for researchers and developers to exchange innovative ideas, information and significant research achievements; and provides a unique opportunity in which both technology and social science meet. Two main tracks for information processing management and communication will be held, covering both research and application works of information management, intelligent information processing, interaction management, networking /telecommunications, and social interaction. This year's conference contains 4 outstanding speeches from distinguished keynote speakers, 12 oral sessions, 3 poster sessions, and 4 short sessions. This year's review process was very competitive and rigorous, which resulted in a very strong and pivotal conference program. We received 228 submissions from many countries around the world. As a result of a neat, careful and strict review process, we selected 88 papers to be presented in the oral and poster sessions (38.9% acceptance rate). All of the accepted papers not only consist of novel ideas, new results, work in progress, and state-of-the-art techniques, but also provide us with the directions and stimulation for future research activities in the area of information management and communication technologies.
