Guest Editorial: Special Issue for NCS 2019

The National Computer Symposium 2019 (NCS 2019) held on November 14-15, 2019 in National Quemoy University, Taiwan. This symposium is held every two years. It brought together experts, researchers, scientists, and engineers from around the world to share their experiences and exchange opinions, and promote exchanges between industry, government and academia. This symposium enhanced the software research and development capabilities of information talents, promoted the development of industry-university cooperation, and took innovation and creativity as the basic spirit of the symposium. It is hoped that computer development will be promoted and the high-tech industries will also be promoted. With pleasure, we present this special issue of Journal of Internet Technology (JIT), devoted to NCS 2019. We invite some outstanding accepted papers in their extended versions and widely open for other submissions to this special issue. Each paper submitted to this special issue was rigorously reviewed by at least two reviewers in the corresponding research areas. Finally, about five papers are selected for this special issue.
