Meeting Description:

The joint MWE-LEX workshop addresses two domains – multiword expressions and (electronic) lexicons – with partly overlapping communities and research interests, but divergent practices and terminologies.

Multiword expressions (MWEs) are word combinations, such as by and large, hot dog, pay a visit or pull one's leg, which exhibit lexical, syntactic, semantic, pragmatic or statistical idiosyncrasies. MWEs encompass closely related linguistic objects: idioms, compounds, light-verb constructions, rhetorical figures, institutionalised phrases and collocations. Because of their unpredictable behavior, notably their non-compositional semantics, MWEs pose problems in linguistic modelling (e.g. treebank annotation, grammar engineering), NLP pipelines (notably when orchestrated with parsing), and end-user applications (e.g. information extraction). Modelling and processing of MWEs has been the topic of the MWE workshop, organised over the past years by the MWE section of SIGLEX.

Because MWE-hood is a largely lexical phenomenon, appropriately built electronic MWE lexicons turn out to be quite important for NLP. Their conception opens up, among others, the issues of lemmatization and of standardised representation of morphological, syntactic and semantic properties of MWEs. Large standardised multilingual, possibly interconnected, NLP-oriented MWE lexicons prove indispensable for NLP tasks such as MWE identification, due to its critical sensitivity to unseen data. But the development of such lexicons is challenging and calls for tools which would leverage, on the one hand, MWEs encoded in pre-existing NLP-unaware lexicons and, on the other hand, automatic MWE discovery in large non-annotated corpora.

Final Call for Papers:

This joint workshop addresses two domains – multiword expressions and (electronic) lexicons – with partly overlapping communities and research interests, but divergent practices and terminologies.

The workshop features two tracks:
A regular research track, where the submissions must be substantially original.
A shared task track, with submissions consisting of system description papers.
The regular research track submissions should follow one of the 2 formats:
* Long papers (9 content pages + references): Long papers should report on solid and finished research including new experimental results, resources and/or techniques.
* Short papers (4 content pages + references): Short papers should report on small experiments, focused contributions, ongoing research, negative results and/or philosophical discussion.

The decisions as to oral or poster presentations of the selected papers will be taken by the PC chairs. No distinction between papers presented orally and as posters is made in the workshop proceedings. There is no limit on the number of reference pages. The submission will be double-blind. Papers available as preprints can also be submitted provided that they fulfil the conditions defined by the ACL Policies for Submission, Review and Citation.

All papers should be submitted via the workshop's START space
Please follow the guidelines and use the COLING 2020 style files available at Please choose the appropriate track (research/shared task) and for research papers the submission modality (long/short).

MWE-LEX 2020 will host edition 1.2 of the PARSEME shared task on semi-supervised identification of MWEs. Details are available at

All deadlines are at 23:59 UTC-12 (anywhere in the world).
September 2, 2020: Workshop papers due date (short papers, long papers, system description papers)
October 16, 2020: Notification of acceptance
November 1, 2020: Camera-ready papers due
