Joint Workshop on Multiword Expressions and WordNet (MWE-WN 2019)

ACL 2019 (Florence, Italy), August 2nd, 2019
Final call for papers

Organised, sponsored and endorsed by SIGLEX, the Special Interest Group on the Lexicon of the ACL Endorsed by GWN, Global Wordnet Association

As a joint event, this workshop addresses two domains – multiword expressions and Wordnets – with partly overlapping communities and research interests, but relatively divergent practices and terminologies.

Multiword expressions (MWEs) are word combinations, such as all of a sudden, a hot dog, to pay a visit or to pull one’s leg, which exhibit lexical, syntactic, semantic, pragmatic and/or statistical idiosyncrasies. MWEs encompass closely related linguistic objects such as idioms, compounds, light verb constructions, rhetorical figures, institutionalised phrases or collocations. Modelling and computational aspects of MWEs have been covered by the Multiword Expression Workshop, organised over the past years by the MWE section of SIGLEX. Because of their unpredictable behavior, and most prominently their non-compositional semantics, MWEs pose special problems in linguistic modelling (e.g. treebank annotation and grammar engineering), in NLP pipelines (e.g. when their orchestration with parsing is concerned), and in end-use applications (e.g. information extraction or machine translation).

From its very beginning, Princeton WordNet has included MWEs, and linked their meanings into a shared network: talk, blab, sing, spill the beans, let the cat out of the bag, tattle, peach, babble, babble out, blab out “divulge confidential information or secrets”. Indeed, over 50% of entries in the Princeton WordNet of English are MWEs and most other wordnets have a similarly high percentage. However, MWEs are generally encoded as a string, with no internal information about syntactic structure or compositionality. Many suggestions for richer encodings have been made but not yet widely adopted, partly because of the cost of adding richer data to already large lexicons.

For the above reasons, the MWE and WN communities are organizing this joint event, which should allow better convergences and scientific innovation. We call for papers focusing on research related (but not limited) to the following topics.

Joint topics on MWEs and Wordnets

MWE-specific topics

Note that, with the intention to also perpetuate previous converging effects with the Construction Grammar community (see the LAW-MWE-CxG 2018 workshop), we extend the traditional MWE scope to include grammatical constructions.


There are two tracks:

The regular research track submissions should follow one of the 2 formats:

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. Authors will be granted an extra page for the final version of their papers. The submission will be double-blind, as understood by the ACL 2019 submission policy. The reported research should be substantially original. Papers available as preprints can also be submitted provided that they fulfil the conditions defined by the new ACL Policies for Submission, Review and Citation. For both types of submissions in this track, the ACL 2019 templates should be used.

The dissemination track submissions are not anonymous, and they should not exceed one page, including the authors’ names and affiliations, the mention of the original venue, the link to the original paper and a short explanation why the paper is relevant to MWEs and Wordnets workshop. If the original paper is not publicly available, it should also be submitted in a separate .pdf file but it does not have to follow the ACL 2019 template.

All papers should be submitted via the following START space:

Please choose the appropriate track (research/dissemination) and for research papers the submission modality (long/short). Multiple submissions A paper that has been or will be submitted to other venues can be submitted to the MWE-WN workshop but the authors must indicate this fact in the submission form. The paper must be withdrawn from the other venue if accepted by the workshop. Conversely, if the paper has been accepted by another venue before being accepted by the MWE-WN workshop, it must be withdrawn from the workshop.
