COVID-19 Update

Sep 17, 2021

DL 2021 will run in a hybrid mode without major issues. Despite an increasing number of cases in Slovakia, Bratislava is one of the less affected regions and shall remain so due to the very high vaccination rate. DL will open during the best Green level 1 of the Slovak Covid automaton, with countermeasures such as mandatory face masks (interior, public transport, etc.) and social distancing (2 m), etc. Starting on Monday, Sep 20, Bratislava will switch to the Orange level 2. This will result in slightly stricter countermeasures, including reduced number of customers in shops, and verification of Green Passes during DL and in restaurants.

As of Sep 16, Slovak authorities also announced a less strict regime on the borders which should result in less checks. Green Passes, full vaccination (to avoid quarantine), and online self-declaration (eHranica) before you travel are still required. See our Covid-19 info page for more details and links.

The DL workshop is the major annual event of the description logic research community. It is the forum in which those interested in description logics, both from academia and industry, meet to discuss ideas, share information and compare experiences.

The 34^th edition will be held in Bratislava, Slovakia from September 19^th to September 22^nd, 2021. It will be co-located with a number of events as part of Bratislava Knowledge September (BAKS 2021). In particular, DL is co-located with two satellite workshops: AKMIS and DAO-XAI.
