+====== Working Group 4: Quantifying and promoting diversity ======
+  * **Leader**: [[https://cental.uclouvain.be/team/mcdm/|Marie-Catherine de Marneffe]] (Belgium)
+  * **Vice-leader**: [[https://www.ukr.uni-jena.de/members/olha-kanishcheva|Olha Kanishcheva]] (Germany/Ukraine)
+==== Workplan ====
+This WG is transversal to WGs 1-3 and will focus on how the Action serves inter- and intra-linguistic
+diversity. Its activities will overlap with the 3 other WGs in:
+  - **Networking** for diversity:
+     * bringing together pre-existing groups dedicated to NLP-applicable universality,
+     * integrating experts of (notably low-resourced) languages not yet covered by these groups,
+     * integrating experts in linguistic typology;
+  - **Quantifying** diversity:
+     * designing **measures of inter- and intra-linguistic diversity** in language resources and tools,
+     * using these measures to quantify diversity in UD and PARSEME corpora;
+  - Promoting diversity:
+     * procedures for **better use of the existing resources**, based on their estimated diversity,
+     * **selecting new data** to be annotated, so as to favour intra-linguistic diversity,
+     * designing **evaluation scenarios** which favour tools performing well on rare and diverse phenomena and low resourced languages,
+     * integrating and **training** new experts dedicated to low-resourced and endangered languages,
+     * validating the unified annotation **guidelines** (WG1) and **lexicon formats** (WG2) against newly included languages and defining new language-specific categories and extensions, if needed,
+     * coordinating the creation and enhancement of annotated **corpora** and **lexica** for low-resourced languages,
+     * discovering and analysing **rare** linguistic **phenomena**, and describing them in resources and tools,
+     * coordination of the development of NLP **tools** (WG3) for low-resourced and endangered languages.
+==== Current Subtasks ====
+  * **Task 4.1**: Promoting low-resourced/endangered languages [co-leaders: Lucia Amoros, Abigail Walsh]
+  * **Task 4.2**: Survey of diversity measures [leader: Louis Estève]
