It was supported by the NexusLinguarum COST Action CA18209 - European network for Web-centred linguistic data science, and participation to the conference was free of charge. NexusLinguarum also supported the proceedings as an open access publication by OASICS. The conference received additional support from the European H2020 project Prêt-à-LLOD and from the Universidad Zaragoza.
The main conference took place on September 2nd and September 3rd. It was located at the beautiful venue of the Paraninfo Building of the University of Zaragoza, which is hosting not only its ceremonial hall but also a library and a museum of natural sciences.

The main conference was organized in 8 sessions:
We initially counted on 258 registered participants, and the total number of unique participants was 212, 40 of them joining the conference physically in Zaragoza.
The conference attracted a high number of participants, more than doubling the number of participants of the former editions. We think that this is to a large part due to the support by NexusLinguarum, allowing a free registration to the event.
