23rd European Semantic Web Conference (ESWC)

May 10-14, 2026 | Dubrovnik , Croatia

History

This conference series started its life as the European Semantic Web Symposium (ESWS), which was held in Heraklion, Greece in May of 2004. The event was established by the SEKT, DIP, and KnowledgeWeb projects that made up the SDK cluster. Based on the success of this first event, the symposium was expanded and upgraded to a conference with the new name the European Semantic Web Conference (ESWC).

From 2005 through to 2008, the conference has grown in stature and quality, visiting Budva in Montenegro, Innsbruck in Austria, and Tenerife in Spain. The SDK Cluster that initially established the conference series later became known as ESSI with the addition of the ASG project. ESSI was the major seed for the establishment of STI International, which now runs the series as one of its major activities. In 2009 the conference returned to its spiritual home in Heraklion, Greece.

From 2010 on, the ESWC is named ‘Extended Semantic Web Conference’ to underline the extended scope and international character behind the event.
