===== Subtask 1: MWE identification =====
This subtask is an extension of [[https://gitlab.com/parseme/corpora/-/wikis/home#shared-tasks|PARSEME shared tasks]] on automatic identification of verbal MWEs.
  * Task: Given a raw text, automatically underline MWEs in it
  * Data: PARSEME 2.0 annotated corpora (not necessarily all the texts from release 1.3)
  * Language teams willing to participate with PARSEME data
    * Albanian
    * Egyptian (ca. 2700-2000 BC): MWEs from the UD-EUJA treebank.
    * Georgian
    * Greek (Modern)
    * Greek (Ancient) 
    * Hebrew
    * Japanese
    * Lithuanian
    * Persian (Farsi)
    * Polish
    * Romanian
    * Serbian
    * Slovene
    * Swedish
    * Ukrainian
  * Minimum annotation effort: 2000 annotated MWEs

===== Subtask 2: MWE paraphrasing =====
  * Task: Given a sentence with a MWE, rephrase a sentence so that there is no MWEs but the meaning is the same
  * Examples:
    * //She made up her mind to…// => //She finally decided to…//
    * //He kicked the bucket// ===> //He died// (But __not__ //He passed away//)
  * Data:
    * Selected sentences form PARSEME annotated corpora
    * The same sentences manually paraphrased
    * One to several hundred examples per language
  * Language teams willing to participate
    * Albanian
    * French
    * Greek (Modern)
    * Japanese
    * Hebrew
    * Lithuanian
    * Persian (Farsi)
