*EXTENDED DEADLINE: September 9, 2020*

*Organised, sponsored and endorsed by:  **SIGLEX* <http://www.siglex.org/>*,

<https://www.aclweb.org/>*ELEXIS* <https://elex.is/>* - European
Lexicographic Infrastructure*

This joint 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
<http://multiword.sourceforge.net/> of SIGLEX <http://www.siglex.org/>.

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 lemmatisation 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.

In order to pave the way towards a better understanding of these issues,
and to foster convergence and scientific innovation, the MWE and ELEXIS
(European Union's Horizon 2020 research grant 731015) communities put
forward a joint event and call for papers on research related (but not
limited) to:

*Joint topics on MWEs and e-lexicons:*

·         Extracting and enriching MWE lists from traditional
human-readable lexicons for NLP use

·         Formats for NLP-applicable MWE lexicons

·         Interlinking MWE lexicons with other language resources

·         Using MWE lexicons in NLP tasks (identification, parsing,
translation, ...)

·         MWE discovery in the service of lexicography

·         Multiword terms in specialised lexicons

·         Representing semantic properties of MWEs in lexicons

·         Paving the way towards encoding lexical idiosyncrasies in

*MWE-specific topics:*

·         Computationally-applicable theoretical work on MWEs and
constructions in psycholinguistics, corpus linguistics and formal grammars

·         MWE and construction annotation in corpora and treebanks

·         Processing of MWEs and constructions in syntactic and semantic
frameworks (e.g. CCG, CxG, HPSG, LFG, TAG, UD, etc.), and in end-user
applications (e.g. information extraction, machine translation and

·         Original discovery and identification methods for MWEs and

·         MWEs and constructions in language acquisition and in
non-standard language (e.g. tweets, forums, spontaneous speech)

·         Evaluation of annotation and processing techniques for MWEs and

·         Retrospective comparative analyses from the PARSEME shared tasks
on automatic identification of MWEs

Our intention is to also perpetuate previous converging effects with the
Construction Grammar and WordNet community (see the LAW-MWE-CxG 2018
<http://multiword.sourceforge.net/lawmwecxg2018/> and MWE-WN 2019
<http://multiword.sourceforge.net/mwewn2019/> workshops). Therefore, we
extend the traditional MWE scope to grammatical constructions and we
include WordNets in the scope of e-lexicons.

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, depending on the available infrastructure
for virtual participation. 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 https://coling2020.org/pages/submission. Please choose the appropriate
track (research/shared task) and for research papers the submission
modality (long/short).

MWE-LEX 2020 hosts edition 1.2 of the PARSEME shared task on
semi-supervised identification of MWEs. This is a follow-up of editions 1.0
(2017) <http://multiword.sourceforge.net/sharedtask2017>, and 1.1 (2018)
<http://multiword.sourceforge.net/sharedtask2018>. Edition 1.2 features (a)
improved and extended corpora annotated with MWEs, (b) complementary
unannotated corpora for unsupervised MWE discovery, and (c) evaluation
focusing on unseen MWEs. Following the synergy with Elexis, our aim is to
foster the development of unsupervised methods for MWE lexicon induction,
which in turn can be used for identification. Authors may submit system
description papers to the shared task track. The system evaluation phase is
now over, results and instructions for system description papers are
available at http://multiword.sf.net/sharedtask2020

All deadlines are at 23:59 UTC-12 (anywhere in the world).
