The 2nd ICSSE-International Conference on Software and Services Engineering was held during March 15-17, 2019. The conference is supported by many universities and research institutes. Many professors play an important role in the successful holding of the conference, so we would like to take this opportunity to express our sincere gratitude and highest respects to our keynote speakers and reviewers. They have worked very hard in reviewing papers and making valuable suggestions for the authors to improve their work. At the same time, we also express our sincere thanks for the understanding and support of every participant. Owing to time constraints, imperfection is inevitable, and any constructive criticism is welcome. Good news. All papers of ICSSE2019 have been indexed by EI Compendex and Scopus.
