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

Association for Computational Linguistics (SIGLEX)

=================================================================

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 interested in
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 will discuss papers 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!
