Keynote speakers

This year, we are going to have two amazing talks by:

Sabine Schulte im Walde, University of Stuttgart

Steven Bird, Charles Darwin University


Multiword expressions (MWEs) are word combinations which exhibit lexical, syntactic, semantic, pragmatic and/or statistical idiosyncrasies (Baldwin & Kim 2010), 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, phrasal verbs, rhetorical figures, collocations, institutionalised phrases, etc. Their behaviour is often unpredictable; for example, their meaning often does not result from the direct combination of the meanings of their parts. Given their irregular nature, MWEs often pose complex problems in linguistic modelling (e.g. annotation), NLP tasks (e.g. parsing), and end-user applications (e.g. natural language understanding and MT), hence still representing an open issue for computational linguistics (Constant et al. 2017).

For almost two decades, modelling and processing MWEs for NLP has been the topic of the MWE workshop organised by the MWE section of SIGLEX in conjunction with major NLP conferences since 2003. Impressive progress has been made in the field, but our understanding of MWEs still requires much research considering its need and usefulness in NLP applications. For this 18th edition of the workshop, we identified three topics on which contributions are particularly encouraged:

Through this workshop, we would like to bring together and encourage researchers in various NLP subfields to submit MWE-related research, so that approaches that deal with processing of MWEs including processing for low-resource languages and for various applications can benefit from each other. We also intend to consolidate the converging effects of previous joint workshops LAW-MWE-CxG 2018, MWE-WN 2019 and MWE-LEX 2020, and the joint MWE-WOAH panel in 2021, extending our scope to MWEs in e-lexicons and WordNets, MWE annotation, as well as grammatical constructions. Correspondingly, we will call for papers on research related (but not limited) to MWEs and constructions in:

Joint session with SIGUL 2022 Workshop

Pursuing its efforts in building bridges with other communities, the MWE Section organises a joint session with the workshop of the Special Interest Group on Under-resourced Languages (SIGUL 2022). The goal is to foster future synergies that could address scientific challenges in the creation of resources, models and applications to deal with multiword expressions and related phenomena in low-resource scenarios, in accordance with one of our special topics in MWE 2022. The session will feature a joint poster session and a joint keynote talk by Steven Bird.

Submission modalities

The workshop invites two types of submissions:

All papers should be submitted via the workshop’s START submission space. Please choose the appropriate link for standard Archival submission or for the Non-archival submission. Registering to the workshop will be necessary to present both archival and non-archival submissions. Presentation and participation formats (on-line, on-site, both) will depend on LREC 2022 main conference arrangements and will be announced later.

Instructions for authors

The double-blind submissions (Archival submissions) should adhere to the ACL Author Guidelines. There is no limit on the number of reference pages.

The PMWE book series editors have put forward a list of conventions to cite multilingual MWE examples and a checklist for PMWE authors. Parts of the checklist are specific to PMWE authors, but sections like Terms, abbreviations and spelling can be relevant for MWE 2022 submissions. We encourage authors to adopt these conventions whenever relevant, without enforcing them. We hope that, in the long term, these could become widely adopted standards in the community.

All submissions should be made via the workshop’s START space. Please choose the appropriate submission modality as described in the Sumbission modalities section above.

Paper Submission Deadline: April 17, 2022
