 The objectives of this internship are to exploit word embeddings for discovery of new MWEs based on their semantic proximity to the previously seen MWEs, contained in a lexicon or in an annotated corpus (resources of both types belong to the outcomes of the PARSEME-FR project). The discovery should lead to (semi-)automatic enrichment of these initial resources. Two stages are to be considered: The objectives of this internship are to exploit word embeddings for discovery of new MWEs based on their semantic proximity to the previously seen MWEs, contained in a lexicon or in an annotated corpus (resources of both types belong to the outcomes of the PARSEME-FR project). The discovery should lead to (semi-)automatic enrichment of these initial resources. Two stages are to be considered:
-  * (i) candidates for new MWEs are generated by replacing individual components of known MWEs by their semantically close words, established notably via word embeddings; +  * candidates for new MWEs are generated by replacing individual components of known MWEs by their semantically close words, established notably via word embeddings; 
-(ii) the candidates generated in this way are filtered based on their corpus frequency or contexts of occurrence; for instance, adjectives chaud/froid ‘hot/cold’ tend to co-occur more frequently with prendre un bain/une douche ‘to take a bath/shower’ than with prendre une baignoire (spacieuse/solide...) ‘take a (huge/solid) bathtub’. +  the candidates generated in this way are filtered based on their corpus frequency or contexts of occurrence; for instance, adjectives //chaud/froid// ‘hot/cold’ tend to co-occur more frequently with //*prendreun **bain**/une **douche**// ‘to take a bath/shower’ than with //**prendre** une **baignoire**// (spacieuse/solide...) ‘take a (huge/solid) bathtub’.
-Possible extensions: +
-(iii) integrating MWE discovery with MWE identification in varIDE1 +
-(iv)  coupling word embedding-based lexical replacement with semantic resources such as WordNet. +
-  * Study the linguistic properties of French multiword expressions, through the exploration of a verbal MWE lexicon extracted from the Lexicon-Grammar tables (Gross 1984) +
-  * Develop a tool to automatically link annotated verbal MWEs and their corresponding entries in the lexicon, using matching procedures based on some normalization of the expressions. For instance, a lexicon entry like //to spill the beans// should be linked to its corpus occurrences like //the beans he spilled//, //spilling the beans// etc. +
-  * Develop a web interface in order to search annotated expressions via multicriteria filters and to visualize their tree-like linguistic description +
-  * Optionally, extend the work to all multiword expressions, which involves the automatic conversion of an existing dictionary of nominal, adjectival and adverbial compounds into the PARSEME-FR format, in particular using syntactic information available in the annotated corpus+
