We invite two types of original and unpublished works: Long papers (8 pages) should describe solid results with strong experimental, empirical or theoretical/formal backing, short papers (4 pages) should describe work in progress where preliminary results have already been worked out. Accepted papers will appear in the workshop proceedings. All papers are allowed an unlimited but sensible number of references. Final camera-ready versions will be allowed an additional page of content to address reviewers’ comments. All submissions must be anonymized, in PDF format (using the EMNLP 2021 style sheets for the main conference; see https://2021.emnlp.org/call-for-papers/style-and-formatting) and must be made through the Softconf website set up for this workshop (https://www.softconf.com/emnlp2021/ECONLP/).
