CALL FOR EVALUATION RESOURCES

LREC2008 - Towards a Shared Task for Multiword Expressions (MWE
2008)

endorsed by the ACL Special Interest Group on the Lexicon (SIGLEX)


Date: Sunday, 1 June 2008
Location: Marrakech, Morocco

########################################################

In recent years, considerable progress has been made in our
understanding of
multiword expressions (MWE), the development of algorithms for their
automatic
extraction from corpora, and the automatic identification of additional
properties such as morphosyntactic preferences or the interpretation of
semi-compositional expressions.

It is difficult to compare results of the many published studies on
MWEs and
obtain a broader perspective, though, because algorithms and implemented
systems have been evaluated on vastly different gold standards and
corpora, in
different languages, for different subtypes of MWEs, etc. In order to
make the
next big step forward, the field of MWE research needs a shared task
in which
different approaches are applied to the same data sets, allowing
completely
new insights to be gained. Since there is as yet not a clear and
universally
accepted definition of multiword expressions, the first instalment of
this
shared task will be of a more exploratory nature than the competitions
that
have been carried out in other areas of computational linguistics.

The MWE 2008 workshop is primarily intended as a forum for collecting,
sharing
and exploiting MWE evaluation resources. We solicit contributions of
such
resources from the MWE community, in particular:

(1) manually annotated data sets (MWE candidates marked as true and
false
positives, or as different subtypes of MWEs);

(2) data sets of MWEs annotated with additional properties; and

(3) lists of known MWEs, e.g. from machine-readable dictionaries.

In addition, candidate data obtained from corpora with sophisticated
proprietary NLP tools may be of interest, helping researchers to apply
their
statistical MWE identification techniques to a broad range of languages.

The contributed resources will be made available freely for research
purposes
on multiword.sf.net, and should be accompanied by documentation (e.g.
annotation guidelines) on the SourceForge project wiki. Contributors
will be
invited to submit a short paper (4 pages) describing their resource and
summarising previous research carried out on these data.

After collection of the resources, teams participating in the shared
task can
evaluate their MWE extraction algorithms on multiple data sets and
discuss
implications for their generalisability and further development. At the
workshop, the evaluation results of the different teams will be
summarised and
compared. A call for papers and participation in the shared task is
being
distributed separately.


SUBMISSION INFORMATION

If you are interested in contributing a MWE evaluation resource to our
initiative, please contact us by e-mail to make further arrangements.

If you have a SourceForge account, you will be able to upload the
resource yourself
and document it on the project wiki.
