Message from the Editors The Sixth Conference on Software Engineering and Information Management (SEIM- 2021) opens its doors to young researchers and practitioners in different areas of computer science and software engineering, providing an opportunity to present their research, discuss state-of-the-art technology and engage in useful networking. As before, we consider SEIM to mainly focus on researchers who are just starting out their scientific careers, and hope to ease their introduction to the conference process. On the other hand, SEIM might also be of interest to more experienced researchers, who are aimed at sharing their research with a wider scientific community. The conference welcomes submissions on a wide range of topics, including but not limited to: • Algorithms and data structures • Mobile systems • Big data • Modelling • Cloud systems • Natural language processing • Coding theory • Networks and telecommunications • Compilers • (Non-)relational databases • Crowdsourcing • Operating systems • Data storage and processing • Programming languages • Development management • Recommendation systems • Digital signal processing • Robotics • Distributed systems • Semantic web • E-commerce / e-government • Social networks • Empirical software engineering • Software analysis • High-performance computing • Software testing • Information retrieval • Software verification • Information security • Software virtualization • Intelligent data analysis • Software-defined networks • Internet of Things • Theoretical computer science • Machine learning • Visual languages This year we received 30 papers, each reviewed by at least 3 members of the Program Committee, of which six were selected for publication in CEUR-WS.org. We would like to thank the members of our Program Committee for their continuous work and contribution to the success of our conference. These proceedings include the SEIM-2021 papers, which were selected by the Program Committee for publication in CEUR-WS.org. These papers passed not only the original review procedure, but also an additional round of post-review with the conference feedback. We thank the authors for their submissions to SEIM-2021 and hope to see them in the future. Furthermore, we would also like to thank Tatiana Mironova, Sergey Zherevchuk and Svyatoslav Mikhailov for their great help in organizing the conference, Computer Science Center for hosting the event, and JetBrains Research for their overall support.
