This volume contains the full research papers, short research papers, posters,
demonstrations, PhD symposium papers, tutorials, and extended abstracts for the
keynotes of the 21st International Conference on Web Engineering (ICWE 2021), held
from May 18–21, 2021, in Biarritz, France [virtually].
ICWE 2021 focused on eight research themes, namely, Semantic Web, Social Web,
Web Modeling and Engineering, Web Big Data and Data Analytics, Web Mining and
Knowledge Extraction, Web of Things, Web Programming, and Web User Interfaces
The comprehensive program would not have been possible without the support
of the many people that contributed to the successful organization of this event. We
would like to thank all the Special Issues, Tutorials, Workshops, Demonstrations and
Posters, PhD Symposium, Publicity, Website, Local Arrangements, and Finance Chairs
for their dedication and hard work. Our thanks goes also to Ricardo Baeza-Yates
(Northeastern University, USA), Christos Faloutsos (Carnegie Mellon University,
USA), and Fabrizio Silvestri (Sapienza University of Rome, Italy) who accepted to be
our keynote speakers. Alessandro Bozzon and Oscar Diaz deserve special thanks for
their support and encouragement in setting up ICWE 2021. We would like to also thank
André Langer and Martin Gaedke for hosting the conference website. We are grateful
to Springer for making possible the publication of this volume. In addition, we thank
the reviewers for their hard work that allowed us to select the best papers to be
presented at ICWE 2021. Last but not least, we would like to thank the authors that sent
their work to ICWE 2021 and all the participants that contributed to the success of this
conference.
