ACL 2005 WORKSHOP ON DEEP LEXICAL ACQUISITION
Sponsored by the ACL Special Interest Group on the Lexicon (SIGLEX)
30 June, 2005
Ann Arbor, USA

Submission deadline: 11 April, 2005
WORKSHOP DESCRIPTION
In natural language processing (NLP), there is a pressing need to develop
deep lexical resources (e.g. lexicons for linguistically-precise grammars,
template sets for information extraction systems, ontologies for word sense
disambiguation). Such resources are critical for enhancing the performance
of systems and for improving their portability between domains. For
example, to perform reliably, an information extraction system needs access
to high-quality lexicons or templates specific to the task at hand.
Most deep lexical resources have been developed manually by lexicographers.
Manual work is costly and the resulting resources have limited coverage,
and require labour-intensive porting to new tasks. Automatic lexical
acquisition is a more promising and cost-effective approach to take, and is
increasingly viable given recent advances in NLP and machine learning
technology, and corpus availability.
While advances have recently been made in some areas of automatic deep
lexical acquisition, a number of important challenges need addressing
before benefits can be reaped in practical language engineering:
* Acquisition of deep lexical information from corpora
While corpus data has been successfully applied in learning certain types
of
deep lexical information (e.g. semantic relations, subcategorization,
selectional preferences), there remain a broad range of lexical relations
that corpus-based techniques have yet to be applied to.
* Accurate, large-scale, portable acquisition techniques
One of the biggest current research challenges is how to improve the
accuracy of existing acquisition techniques further, at the same time as
improving both scalability and robustness.
* Use of deep lexical acquisition in recognised applications
Although lexical acquisition has the potential to boost performance in
many
NLP application tasks, this has yet to be demonstrated for many important
applications.
* Multilingual deep lexical acquisition
For theoretical and practical reasons it is important to test whether
techniques developed for one language (typically English) can be used to
benefit research on other languages.
TARGET AUDIENCE
The workshop will be of interest to anyone interested in automatically
acquired deep lexical information, e.g. in the areas of computational
grammars, computational lexicography, machine translation, information
retrieval, question-answering, and text mining. Areas of Interest
* Automatic acquisition of deep lexical information:
o subcategorization
o diathesis alternations
o selectional preferences
o lexical / semantic classes
o qualia structure
o lexical ontologies
o semantic roles
o word senses
etc.
* Methods for supervised, unsupervised and weakly supervised deep lexical
acquisition (machine learning, statistical, example- or rule-based,
hybrid
etc.)
* Large-scale, cross-domain, domain-specific and portable deep lexical
acquisition
* Extending and refining existing lexical resources with automatically
acquired information
* Evaluation of deep lexical acquisition
* Application of deep lexical acquisition to NLP applications (e.g.
machine
translation, information extraction, language generation,
question-answering)
* Multilingual deep lexical acquisition
IMPORTANT DATES

Workshop date: 30 June, 2005
SUBMISSION DETAILS
Requirements
Papers should describe original work; they should emphasize completed work
rather than intended work, and should indicate clearly the state of
completion of the reported results. Wherever appropriate, concrete
evaluation results should be included. Submissions will be judged on
correctness, originality, technical strength, significance and relevance to
the conference, and interest to the attendees.
A paper accepted for presentation at the workshop, cannot be presented or
have been presented at any other meeting with publicly available published
proceedings. Papers that are being submitted to other conferences or
workshops must indicate this on the title page, as must papers that contain
significant overlap with previously published work. Reviewing
The reviewing of the papers will be blind. Each submission will be reviewed
by at least three programme committee members. Submission Information
Submissions should follow the two-column format of ACL proceedings and
should not exceed eight (8) pages, including references. We strongly
recommend the use of ACL-05 LaTeX style files or Microsoft Word Style
files. They are available at http://www.aclweb.org/acl2005/styles/. A
description of the format is also available in case you are unable to use
these style files directly. Papers must conform to the official ACL-05
style guidelines, and we reserve the right to reject submissions that do
not conform to these styles including font size restrictions.
As reviewing will be blind, the paper should not include the authors' names
and affiliations. Furthermore, self-references that reveal the author's
identity, e.g., "We previously showed (Smith, 1991) ...", should be
avoided. Instead, use citations such as "Smith previously showed (Smith,
1991) ...". Papers that do not conform to these requirements will be
rejected without review.
Papers should be submitted electronically in BOTH Postscript and PDF format
to: dla-acl2005@unimelb.edu.au
The following identification information should be sent in a separate email
with the subject line "ACL2005 WORKSHOP ID PAGE":
Title: title of paper
Authors: list of all authors
Keywords: up to five topic keywords
Contact author: email address of author of record (for correspondence)
