Final Call for Paper Submissions
and Deadline Extension

ACL 2011 Workshop on Multiword Expressions:
from Parsing and Generation to the real world (MWE 2011)

endorsed by the Special Interest Group on the Lexicon of the
Association for Computational Linguistics (SIGLEX)

Portland, Oregon, USA - June 23, 2011

Long papers - Mar 25, 2011 at 23:59 PDT (GMT-7)
Short & demo papers - Apr 01, 2011 at 23:59 PDT (GMT-7)

Under the denomination "Multiword Expression", one can hang a
wide range of linguistic constructions such as idioms (a frog in
the throat, kill some time), fixed phrases (per se, by and large,
rock'n roll), noun compounds (telephone booth, cable car),
compound verbs (give a presentation, go by [a name]), etc. While
easily mastered by native speakers, their interpretation poses a
major challenge for computational systems, due to their flexible
and heterogeneous nature. Surprisingly enough, MWEs are not
nearly as frequent in NLP resources (dictionaries, grammars) as
they are in real-word text, where they have been reported to
account for over 70% of the terms in a domain. Thus, MWEs are a
key issue and a current weakness for tasks like Natural Language
Parsing (NLP) and Generation (NLG), as well as real-life
applications such as Machine Translation.

MWE 2011 will be the 8th event in the series, and the time has
come to move from basic preliminary research and theoretical
results to actual applications in real-world NLP tasks. Therefore,
following further the trend of previous MWE workshops, we propose
a turn towards MWEs on NLP applications, specifically towards
Parsing and Generation of MWEs, as there is a wide range of open
problems that prevent MWE treatment techniques to be fully
integrated in current NLP systems. We will be asking for original
research related (but not limited) to the following topics:

* Lexical representations: In spite of several proposals for
MWE representation ranging along the continuum from words-
with-spaces to compositional approaches connecting lexicon
and grammar, to date, it remains unclear how MWEs should be
represented in electronic dictionaries, thesauri and grammars.
New methodologies that take into account the type of MWE and
its properties are needed for efficiently handling manually
and/or automatically acquired expressions in NLP systems.
Moreover, we also need strategies to represent deep attributes
and semantic properties for these multiword entries.

* Application-oriented evaluation: Evaluation is a crucial
aspect for MWE research. Various evaluation techniques have
been proposed, from manual inspection of top-n candidates to
classic precision/recall measures. However, only application-
oriented techniques can give a clear indication of whether the
acquired MWEs are really useful. We call for submissions that
study the impact of MWE handling in applications such as
Parsing, Generation, Information Extraction, Machine
Translation, Summarization, etc.

* Type-dependent analysis: While there is no unique definition
or classification of MWEs, most researchers agree on some
major classes such as named entities, collocations, multiword
terminology and verbal expressions. These, though, are very
heterogeneous in terms of syntactic and semantic properties,
and should thus be treated differently by applications. Type-
dependent analyses could shed some light on the best
methodologies to integrate MWE knowledge in our analysis and
generation systems.

* MWE engineering: Where do my MWEs go after being extracted?
Do they belong to the lexicon and/or to the grammar? In the
pipeline of linguistic analysis and/or generation, where
should we insert MWEs? And even more important: HOW? Because
all the effort put in automatic MWE extraction will not be
useful if we do not know how to employ these rich resources in
our real-life NLP applications!


MWE 2011 introduces three different submission modalities:

* Regular long papers (8 content pages + 1 page for references):
Long papers should report on solid and finished research
including new experimental results, resources and/or techniques.

* Regular short papers (4 content pages + 1 page for references):
Short papers should report on small experiments, focused contributions,
ongoing research, negative results and/or philosophical discussion.

* System demonstration (2 pages): System demonstration papers should
describe and document the demonstrated system or resources. We
encourage the demonstration of both early research prototypes and
mature systems, that will be presented in a separate demo session.

All submissions must be in PDF format and must follow the ACL
2011 formatting requirements (available at We strongly advise
the use of the provided Word or LaTeX template files. For regular
long and short papers, the reported research should be
substantially original. The papers will be presented orally or as
posters. The decision as to which paper will be presented orally
and which as poster will be made by the program committee based
on the nature rather than on the quality of the work.

Following the example of major conferences like ACL-HLT 2011,
this year we will also accept papers accompanied by the resource
(software or data) described in the paper. Resources will be
reviewed separately and the final acceptance decision will be
made based on both the resource reviews and the paper reviews.
The software or data resources submitted should be ready for
release and should contain at a README file. All resources will
be made available to the MWE community.

Reviewing will be double-blind, and thus no author information
should be included in the papers; self-reference should be
avoided as well. Resources submitted with the papers should be
anonymized for submission. Papers and/or resources that do not
conform to these requirements will be rejected without review.
Accepted papers will appear in the workshop proceedings, where
no distinction will be made between papers presented orally or
as posters.

Submission will be electronic in PDF format through the workshop
START system, available at:

Please chose the appropriate submission type from the starting
submission page, according to the category of your paper, and
remember that long papers must be submitted no later than
March 25, 2011 at 23:59 PDT (GMT-7) and short and demo papers must
be submitted no later than April 1, 2011 at 23:59 PDT (GMT-7).
