ACL-2004 Workshop on
Multiword Expressions: Integrating Processing

26th July 2004, Barcelona, Spain

In recent years, there has been a growing awareness in the NLP community
of the problems that Multiword Expressions (MWEs) pose and the need for
their robust handling.

MWEs  include a large range of linguistic phenomena,  such as phrasal
(e.g. "add up"), nominal compounds (e.g. "telephone box"),  and=20
institutionalized phrases (e.g. "salt and pepper").  These expressions,=20
which can be syntactically and/or semantically idiosyncratic in nature,

are used frequently in everyday language, usually to express  precisely=20
ideas and concepts that cannot be compressed into a single word.

Most real-world applications tend to ignore MWEs or address them simply
listing. However, it is clear that successful applications will need to
able to identify and treat them appropriately. This particularly applies
the many applications which require some degree of semantic
(e.g. machine translation, question-answering, summarisation,
and require tasks such as parsing and word sense disambiguation.

A considerable amount of research has lately been conducted in
this area, some within large research projects dedicated to MWEs.
In this context, a successful workshop on MWEs was held at ACL 2003
(<>), with papers
presenting a cross section of research on MWEs. There is some research
on MWEs in general. Some is very computational, examining detection and
extraction using a variety of methods. Some is more linguistic, focusing
classification of the various types. There is also a lot of research on
particular subtypes of MWEs, especially English phrasal verbs.

In this workshop the focus is on papers that integrate analysis,
and treatment of various kinds of multiword expressions (MWEs) in NLP.
For example,

(1) research that combines a linguistic analysis with a method of
automatically acquiring the classes described

(2) work that combines the computational treatment of a class of MWEs
a solid linguistic analysis

(3) research that extracts MWEs and either classifies them or uses them
some task.

These combinations of research will help to bridge the gap between the
of NLP and the descriptive tradition of linguistics.


The workshop will be of interest to anyone working on MWEs, e.g. in the
areas of computational grammars, computational lexicography, automatic
lexical acquisition, machine translation, information retrieval, text
mining, and computer-assisted language teaching and learning. The=20
objective is to summarise what has been achieved in the area, to=20
establish common themes between different approaches, and to discuss=20
future trends.


Papers are invited on, but not limited to, the following topics:

* Theoretical research on MWEs, including corpus based analysis
* MWE taxonomies, classifications and databases
* Cross-lingual analysis of MWE types, use, and behaviour
* Methods for identification and extraction of MWEs
(machine learning, statistical, example- or rule-based, or hybrid)
* Evaluation of MWE extraction methods
* Methods for determining the compositionality of MWEs
* Integration of MWE data into grammars and NLP applications
(e.g. machine translation and generation)

Papers can cover one or more of these areas, but research that combines
different topics is especially encouraged.


Papers should be submitted electronically in Postscript or PDF format
to: mwe-acl04 at . Submissions should conform to the
two-column format of ACL proceedings and should not exceed eight (8)
pages, including references. We strongly recommend the use of ACL-2004
