The International Workshop on Description Logics is the main annual event
of the Description Logic research community. It is the forum at which those
interested in description logics, from both academia and industry, meet to
discuss ideas, share information, and compare experiences. The workshop explicitly
welcomes submissions from researchers that are new to the area and provides
quality feedback via peer-reviewing, while at the same time being of an inclusive
nature with a very high acceptance rate. There are only informal (electronic)
proceedings and inclusion of a paper in these proceedings should not preclude
its publication at conferences. Further information can be found on the DL web
pages at http://dl.kr.org/.
This volume contains the papers presented at the 34th International Workshop
on Description Logics (DL 2021) held in Bratislava, Slovakia, from
September 19–22, 2021. It will be co-located with a number of events as part of Bratislava
Knowledge September (BAKS 2021). Due to the COVID-19 pandemic, the event
was held in hybrid mode, with online and in-person participation.
