Abstract

The previous 2018 International Conference on Computer Information Science and Application Technology (CISAT 2018) was successfully taken place on December 7-9, 2018 in Daqing, China. All accepted papers were published by Journal of Physics: Conference Series (JPCS) and have been indexed by EI/CPCI.It was a great pressure to welcome all the participants from different countries to the 2019 2nd International Conference on Computer Information Science and Application Technology (CISAT 2019) in Guangzhou, China during August 30-September 1, 2019. This three-day conference was supported by Nanjing University of Aeronautics and Astronautics, China.CISAT 2019 managed to serve as a platform for researchers, developers, engineers, academicians as well as industrial professionals from all over the world to present their research results in the field of computer information science and application technology. Professors from various prestigious universities in China and abroad were invited to deliver keynote talks describing the latest information in their respective areas of expertise. The conference helped those that are of interest to the topics to interact with the experts to get their advice and consult on technical matters, and collaboration opportunities and strategies.In the conference, a large number of papers were received, over 425 of which were accepted after a strict peer reviewing process to be published officially and submitted to EI Compendex and Scopus. The selected papers of the conference cover a wide range of computer science and application technology including intelligent system and control technology, big data search, mining and visualization, image processing and detecting, simulation and analysis based on algorithm and modeling, software engineering and application, etc.We would like to deeply acknowledge all the parties involved in making this conference successfully held: the conference chairs, organizing committee, speakers, presenters, authors and reviewers. We hope that we can grow positive impact on information technology and strengthen the researcher network.The Committee of CISAT 2019List of Organizing Committees, General Conference Chairmen, Local Co-chairmen, International Technical Committee, Technology Program Committee, Conference secretary are available in the pdf.
