Description

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

The MWE Section would like to pursue its efforts in building bridges with other communities. We intend to organise a joint session with the workshop of the Special Interest Group on Under-resourced Languages, SIGUL 2022, which proposal was also submitted to be co-located with LREC 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 format is currently under discussion. This would require some overlap between the schedules of both workshops, implying synchronisation as to whether both of them take place before or after LREC 2022.
