+Preparatory work for next WP2 tasks has also been undertaken: ​
+  * Carlos Ramisch and colleagues developed methods based on word embeddings to perform discovery and semantic processing of MWEs (Cordeiro et al. ACL 2016, Ramisch et al. ACL 2016, Ramisch et al. LREC 2016, Ramisch et al. MWE 2017, Vargas et al. MWE 2017). ​
+  * Waszczuk et Savary (BSNLP 2017) designed an algorithm to project heterogeneous MWE lexicons on a constituent treebank. Cordeiro et al. (SemEval 2016) developed a symbolic method to identify MWEs in a text from a lexicon.

+A group of researchers (Mathieu Constant, Agata Savary, Jean-Yves Antoine, Caroline Pasquer, Takuya Nakamura, Carlos Ramisch) is presently working on an internal format of lexicon in order to encode fine-grained properties of MWEs.

+In the meantime, Agata Savary and colleagues are exploring the platform XMG in order to have an object-oriented encoding of MWEs.(cf. Lichte et al. to appear).
