The Smart Innovation, Systems and Technologies book series encompasses the topics
of knowledge, intelligence, innovation and sustainability. The aim of the series is to
make available a platform for the publication of books on all aspects of single and
multi-disciplinary research on these themes in order to make the latest results avail-
able in a readily-accessible form. Volumes on interdisciplinary research combining
two or more of these areas is particularly sought.
The series covers systems and paradigms that employ knowledge and intelligence
in a broad sense. Its scope is systems having embedded knowledge and intelligence,
which may be applied to the solution of world problems in industry, the environment
and the community. It also focusses on the knowledge-transfer methodologies and
innovation strategies employed to make this happen effectively. The combination
of intelligent systems tools and a broad range of applications introduces a need
for a synergy of disciplines from science, technology, business and the humanities.
The series will include conference proceedings, edited collections, monographs,
handbooks, reference books, and other relevant types of book in areas of science and
technology where smart systems and technologies can offer innovative solutions.
High quality content is an essential feature for all book proposals accepted for the
series. It is expected that editors of all accepted volumes will ensure that contributions
are subjected to an appropriate level of reviewing process and adhere to KES quality
principles.

Preface
The volume contains a selection of papers presented at the 21st International Confer-
ence on Informatics in Economy (IE 2022) entitled Education, Research and Business
Technologies, which was held in Bucharest, Romania, in a hybrid format, on May
26th, 2022.
The IE conference has a quite long tradition. Its first edition was organized in
1993 by the Bucharest University of Economic Studies (ASE) in collaboration with
academics of the Institut National des Sciences Appliquées (INSA) de Lyon, France,
as an event meant to stimulate the exchange of ideas and scientific results in the
context of new evolutions in Romania. While, in the period 1993–2011, the confer-
ence has been initially organized in odd years since 2012, IE has become an annual
event.
The International Conference on Informatics in Economy was, in the early 90s,
one of the first scientific events in this thematic domain ever held in Romania and,
over years, has gained international scientific recognition. At the national level, it
remains one of the most important scientific events that gather the entire Romanian
Economic Informatics community. Many of the papers presented at the conference
have been quality works and, consequently, the volumes of the 11th to 16th editions
were indexed by ISI Thomson Reuters as ISI Proceedings. In 2021, Springer accepted
to publish the proceedings The IE 2021 conference proceedings were published
under the title Education, Research and Business Technologies in the book series,
named Smart Innovation, Systems and Technologies, led by Profs. Robert Howlett
and Lakhmi C. Jain.
The 21st edition of the conference promoted research results in Business
Informatics and related Computer Science topics such as:
. Machine learning theory and applications;
. Data science, big data management, processing, and analytics;
. Smart cities and sustainable communities;
. IoT management and integration with utilities;
. Cloud, distributed and parallel, cloud and sky computing;
. Cybersecurity;
v
vi Preface
. Mobile-embedded and multimedia solutions;
. Platform economy;
. Quantitative economics;
. Enterprise and business solutions;
. E-Society, E-Government and E-Education
The programme included three keynote speeches and 37 regular papers grouped
into five sections. Many papers reflected the international cooperation research works
and were authored by researchers from 12 countries (Brazil, Bulgaria, China, Finland,
Greece, Italy, Republic of Moldova, New Zeeland, Norway, Romania, Russia, and
Switzerland).
A number of 43 regular manuscripts were submitted for evaluation and 37 papers
were accepted by the International Programme Committee.
A number of 29 final versions of the accepted papers are included in the four parts
of the volume:
1. Cloud, Distributed and Parallel Computing, IoT, Mobile-Embedded and Multi-
media Solutions (five papers);
2. E-Society, Enterprise and Business Solutions, Smart Cities and Sustainable
Communities, E-Society, E-Government and E-Education (six papers);
3. Big Data Management, Processing and Analytics, Machine Learning Theory and
Applications (ten papers);
4. Quantitative Economics (eight papers).
This volume can be useful for researchers, consultants, and postgraduate students
in Computer science and design, Business informatics, Economics, and Management.
The editors are grateful to Springer for accepting to publish the proceedings of
IE conference in the Advances in Intelligent Systems and Computing series, and
ensuring a high-quality technical version of the volume. Special thanks are due to
Prof. J. Lakhmi C. Jain for permanent guidance, and the technical assistance of
