Fifth SIGHAN Workshop on Chinese Language Processing
COLING/ACL 2006 Workshop
July 22-23, 2006

Sydney, Australia

Background and Goals

Growing interest in Chinese language processing is leading to the development of
resources such as annotated corpora, word segmenters, part-of-speech taggers,
and parsers. As more resources have become available recently, it is crucial to
create a platform that allows easy exchange of information and data and the
comparison of different approaches to various NLP tasks. The SIGHAN workshops
provide a forum where the latest research in these areas can be shared.

Past SIGHAN workshops included the organization of the First and Second
International Chinese Word Segmentation Bakeoff, where many word segmentation
systems from academia and industry were evaluated. The evaluations conducted
have proven to be influential, and the evaluation data set has become the
benchmark for Chinese word segmentation in the Chinese language processing

COLING/ACL 2006 in Sydney will provide an ideal opportunity to bring together
again influential as well as aspiring researchers from Hong Kong, Mainland
China, Singapore, and Taiwan and other interested Chinese language processing
researchers from around the world, to deliberate and interact on a range of NLP

The first day of the workshop (July 22) will consist of papers on all aspects of
Chinese language processing, including but not limited to:

word segmentation
part-of-speech tagging
lexical semantics
word sense disambiguation
lexicon acquisition
corpus development
discourse processing
cross-lingual information retrieval
machine translation

The second half-day of the workshop (July 23) will present results from a
bakeoff. A SIGHAN business meeting will discuss lessons learned and future
plans. This year's third SIGHAN bakeoff will be held during the Spring of 2006.
This year, in addition to the standard Chinese word segmentation task, we also
plan a new track on named entity recognition and tagging from unsegmented
Chinese text. Training and testing resources will be provided in both
traditional and simplified character sets from a range of institutions including
Chinese Knowledge and Information Processing group of Academia Sinica, City
University of Hong Kong, Microsoft Research Asia, Peking University, and the
Universities of Pennsylvania and Colorado.

Submission Method

Papers should be written in English and may not exceed 8 pages (including all
illustrations, references and appendices, and using 11pt for the main text). We
strongly recommend the use of the LaTeX style files or MS Word document template
provided by COLING/ACL 2006, available at http://www.acl2006.org/program/style.
Since reviewing will be blind, manuscripts should not include authors' names
and affiliations. Papers should be submitted via START, for which more detail
will be available in due course.

Important Dates

Workshop paper submission deadline: April 12, 2006
Notification of acceptance: May 12, 2006
Camera ready version deadline: May 31, 2006

Bakeoff Registration Opens: March 15, 2006

ACL-COLING 2006 Workshop on ''Linguistic Distances''
July 23, 2006
Sydney, Australia


In many theoretical and applied areas of computational linguistics
researchers operate with a notion of linguistic distance or,
conversely, linguistic similarity, which is the focus of the present
workshop. While many CL areas make frequent use of such notions, it
has received little focused attention, an honorable exception being
Lebart & Rajman (2000).

In information retrieval (IR), also the focus of Lebart & Rajman's
work, similarity is at heart of most techniques seeking an optimal
match between query and document. Techniques in vector space models
operationalize this via (weighted) cosine measures, but older tf/idf
models were also arguably aiming at a notion of similarity.

Word sense disambiguation models often work with a notion of
similarity among the contexts within which word (senses) appear, and
MT identifies candidate lexical translation equivalents via a
comparable measure of similarity. Many learning algorithms currently
popular in CL, including not only supervised techniqes such as memory-
based learning (k-nn) and support-vector machines, but also
unsupervised techniques such as Kohonen maps and clustering, rely
essentially on measures of similarity for their processing.

Notions of similarity are often invoked in linguistic areas such as
dialectology, historical linguistics, stylometry, second-language
learning (as a measure of learners' proficiency), psycholinguistics
(acounting for lexical ''neighborhood'' effects, where neighborhoods are
defined by similarity) and even in theoretical linguistics (novel
accounts of the phonological constraints on semitic roots).

The workshop aims to bring together researchers employing various
measures of linguistic distance or similarity, including novel
proposals, especially to demonstrate the importance of the abstract
properties of such measures (validity, stability over corpus size,
computability, fidelity to the mathematical distance axioms), but
also to exchange information on how to analyze distance information
further. We assume that there is a ''hidden variable'' in the
similarity relation, so that we should always speak of similarity with
respect to some property, and we suspect that there is such a plethora
of measures in part because researchers are often inexplicit on this
point. It will useful to tease the different notions apart. Finally,
it is most intriguing if we might make a start on understanding how
some of the different notions might construed as alternative
realizations of a single abstract notion.

Call for papers

Papers are invited on substantial, original, and unpublished research
investigating linguistic distance measures, and their application,
analysis and interpretation. The submission deadline is below.


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 the LaTeX style files or Microsoft Word document
template that will be made available on the conference Web site
(http://www.acl2006.mq.edu.au/). We reserve the right to reject
submissions that do not conform to these styles, including font size

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.

Submission will be electronic. The only accepted format for submitted
papers is Adobe PDF. The papers must be submitted no later than April
1, 2006. Papers submitted after that time will not be reviewed. For
details of the submission procedure, please consult the submission
webpage reachable via the conference website.

Questions regarding the submission procedure should be directed to the
Program Co-Chairs, John Nerbonne and/or Erhard Hinrichs

Papers that are being submitted in parallel to other conferences or
workshops must indicate this on the title page, as must papers that
contain significant overlap with previously published work. Please
use the abstract or the title footnote for noting these complications.
