Due to the current health crisis, SEMANTiCS conference, the leading European conference on Semantic Technologies and AI, will postpone its on-site event to September 6-9, 2021. To keep a minimum level of continuity for 2020 we welcome submissions to the Research & Innovation Track and will publish open access proceedings with Springer LNCS. Please consult our open calls for further details. Stay safe, stay healthy! We are looking forward to meet you again in Amsterdam in 2021!
