17th Workshop on Multiword Expressions (MWE 2021)
Colocated with ACL-IJCNLP 2021 (Bangkok, Thailand), 5 or 6 August 2021
https://multiword.org/mwe2021/
Organised and sponsored by: SIGLEX, the Special Interest Group on the Lexicon
of the ACL
*** Deadline: April 19, 2021 ***
** FIRST CALL FOR PAPERS **
Multiword expressions (MWEs) are word combinations which exhibit lexical,
syntactic, semantic, pragmatic and/or statistical idiosyncrasies (Baldwin & Kim
2010<https://people.eng.unimelb.edu.au/tbaldwin/pubs/handbook2009.pdf>), such
as by and large, hot dog, pay a visit and pull one's leg. The notion
encompasses closely related phenomena: idioms, compounds, light-verb
constructions, rhetorical figures, institutionalised phrases, collocations,
etc. The behaviour of MWEs is often unpredictable, in particular their meanings
are not regularly composed of the meanings of their parts. Thus, MWEs are a
major challenge in computational linguistics (Constant et al.
2017<https://www.aclweb.org/anthology/J17-4005/>), including linguistic
modelling (e.g. treebanking), computational modelling (e.g. parsing), and
end-user NLP applications (e.g. natural language understanding, machine
translation, and social media mining).
Modelling and processing MWEs for NLP has been the topic of the MWE workshop
organised by the MWE section<http://multiword.sourceforge.net/> of
SIGLEX<http://www.siglex.org/> in conjunction with major NLP conferences since
2003. Although much progress has been made in the field, MWE processing in
end-user NLP tasks is currently under-explored, and most studies still
introduce MWEs as future work. Nonetheless, there are recent studies in which
MWEs gained particular attention in end-user applications, including machine
translation (Zaninello & Birch
2020<https://www.aclweb.org/anthology/2020.lrec-1.471/>), text simplification
(Kochmar et al. 2020<https://www.aclweb.org/anthology/2020.lrec-1.545/>, Liu &
Hwa 2016<https://www.aclweb.org/anthology/N16-1040/>), language learning and
assessment (Paquot et al.
2019<https://dial.uclouvain.be/pr/boreal/object/boreal:226339>, Christiansen &
Arnon 2017<https://doi.org/10.1111/tops.12274>), social media mining (Maisto et
al. 2017<https://doi.org/10.4000/books.aaccademia.2441>), and abusive language
detection (Zampieri et al.
2020<https://www.aclweb.org/anthology/2020.semeval-1.188/>, Caselli et al.
2020<https://www.aclweb.org/anthology/2020.lrec-1.760/>).
The special focus for this 17th edition of the workshop is on MWE processing in
end-user applications such as those listed above. On the one hand, the PARSEME
shared tasks (Ramisch et al.
2020<https://www.aclweb.org/anthology/2020.mwe-1.14/>, Ramisch et al.
2018<https://www.aclweb.org/anthology/W18-4925/>, Savary et al.
2017<https://www.aclweb.org/anthology/W17-1704/>), among others, fostered
significant progress in MWE identification, providing datasets, evaluation
measures and tools that now allow fully integrating MWE identification into
end-user applications. On the other hand, NLP seems to be shifting towards
end-to-end neural models capable of solving complex end-user tasks with little
or no intermediary linguistic symbols, questioning the extent to which MWEs
should be implicitly or explicitly modelled. Therefore, one goal of this
workshop is to bring together and encourage researchers in various NLP
subfields to submit MWE-related research, so that approaches that deal with
MWEs in various applications could benefit from each other.
Following the success of previous joint workshops LAW-MWE-CxG
2018<http://multiword.sourceforge.net/lawmwecxg2018/>, MWE-WN
2019<http://multiword.sourceforge.net/mwewn2019/> and MWE-LEX
2020<http://multiword.sourceforge.net/mwelex2020/>, we further extend the scope
of the workshop to MWEs in e-lexicons and WordNets, MWE annotation, as well as
grammatical constructions.
The 17th Workshop on MWEs invites submissions on (but not limited to) the
following topics:
Traditional MWE topics:
· Computationally-applicable theoretical work on MWEs and constructions in
psycholinguistics and corpus linguistics
· MWE and construction annotation and representation in resources such as
corpora, treebanks, e-lexicons and WordNets
· Processing of MWEs and constructions in syntactic and semantic frameworks
(e.g. CCG, CxG, HPSG, LFG, TAG, UD, etc.)
· Discovery and identification methods for MWEs and constructions
· MWEs and constructions in language acquisition, language learning, and
non-standard language (e.g. tweets, speech)
· Evaluation of annotation and processing techniques for MWEs and constructions
· Retrospective comparative analyses from the PARSEME shared tasks on
automatic identification of MWEs
Topics on MWEs and end-user applications:
· Processing of MWEs and constructions in end-user applications (e.g. MT, NLU,
summarisation, social media mining, computer assisted language learning)
· Implicit and explicit representation of MWEs and constructions in end-user
applications
· Evaluation of end-user applications concerning MWEs and constructions
· Resources and tools for MWEs and constructions (e.g. lexicons, identifiers)
in end-user applications
** JOINT SESSION WITH WOAH WORKSHOP **
Pursuing the MWE Section's tradition of synergies with other communities and in
accordance with ACL-IJCNLP 2021's theme track on NLP for social good, we will
organise a joint session with the Workshop on Online Abuse and Harm
(WOAH)<https://www.workshopononlineabuse.com/>. We believe that MWEs are
important in online abuse detection, and that the latter can provide an
interesting testbed for MWE processing technology. The main goal is to pave the
way towards the creation of data for a shared task involving both communities.
The format of the session is under discussion, and we welcome suggestions from
the community. Submissions describing research on MWEs and abusive language,
especially introducing new datasets, are also welcome.
** SUBMISSION MODALITIES **
· Long papers (8 content pages + references) should report on solid and
finished research including new experimental results, resources and/or
techniques.
· Short papers (4 content pages + references) should report on small
experiments, focused contributions, ongoing research, negative results and/or
philosophical discussion.
In regular research papers, the reported research should be substantially
original. Papers available as preprints can also be submitted provided that
they fulfil the conditions defined by the ACL Policies for Submission, Review
and
Citation<https://www.aclweb.org/portal/content/new-policies-submission-review-and-citation>.
Notice that double submission to ACL-IJCNLP 2021 main conference and MWE 2021
is allowed but should be notified at submission time, as per the ACL-IJCNLP
2021 call for
papers<https://2021.aclweb.org/calls/papers/#multiple-submission-policy>:
"[...] papers can be dual-submitted to both ACL-IJCNLP 2021 and an ACL-IJCNLP
2021 workshop which has its submission deadline falling before our notification
date of May 5, 2021."
Submission is **double-blind** as per the ACL-IJCNLP 2021
guidelines<https://2021.aclweb.org/calls/papers/#paper-submission-information>.
For all types of submission, the ACL-IJCNLP 2021
templates<https://2021.aclweb.org/calls/papers/#paper-submission-and-templates>
must be used. There is no limit on the number of reference pages. An extra page
will be allowed to take the reviewers' comments into account in the final
versions of accepted papers (long = 9 content pages, short = 5 content pages).
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
participation (presential and/or virtual). No distinction between papers
presented orally and as posters is made in the workshop proceedings.
All papers should be submitted via the workshop's START space, available soon.
Please choose the appropriate submission modality (long/short).
