In the language engineering and the linguistics communities, research in
comparable corpora has been motivated by two main reasons. In language
engineering, it is chiefly motivated by the need to use comparable
corpora as training data for statistical NLP applications such as
statistical machine translation or cross-lingual retrieval. In
linguistics, on the other hand, comparable corpora are of interest in
themselves by making possible inter-linguistic discoveries and
comparisons. It is generally accepted in both communities that
comparable corpora are documents in one or several languages that are
comparable in content and form in various degrees and dimensions. We
believe that the linguistic definitions and observations related to
comparable corpora can improve methods to mine such corpora for
applications of statistical NLP. As such, it is of great interest to
bring together builders and users of such corpora.

The scarcity of parallel corpora has motivated research concerning the
use of comparable corpora: pairs of monolingual corpora selected
according to the same set of criteria, but in different languages or
language varieties. Non-parallel yet comparable corpora overcome the two
limitations of parallel corpora, since sources for original, monolingual
texts are much more abundant than translated texts.  However, because of
their nature, mining translations in comparable corpora is much more
challenging than in parallel corpora. What constitutes a good comparable
corpus, for a given task or per se, also requires specific attention:
while the definition of a parallel corpus is fairly straightforward,
building a non-parallel corpus requires control over the selection of
source texts in both languages.

Parallel corpora are a key resource as training data for statistical
machine translation, and for building or extending bilingual lexicons
and terminologies. However, beyond a few language pairs such as English-
French or English-Chinese and a few contexts such as parliamentary
debates or legal texts, they remain a scarce resource, despite the
creation of automated methods to collect parallel corpora from the
Web. To exemplify such issues in a practical setting, this year's
special focus will be on

   Language Resources for Machine Translation
   in Less-Resourced Languages and Domains

with the aim of overcoming the shortage of parallel resources when
building MT systems for less-resourced languages and domains,
particularly by usage of comparable corpora for finding parallel data
within and by reaching out for "hidden" parallel data. Lack of
sufficient language resources for many language pairs and domains is
currently one of the major obstacles in further advancement of machine


We solicit contributions including but not limited to the following

Topics related to the special theme:

* comparable corpora use in MT
* comparable corpora processing tools/kits for MT
* parallel corpora usage
* parallel corpora processing tools/platforms
* MT for less-resourced languages
* MT for less-resourced domains
* open source SMT systems (Moses, etc.)
* publicly available SMT

Building Comparable Corpora:

 * Human translations
 * Automatic and semi-automatic methods
 * Methods to mine parallel and non-parallel corpora from the Web
 * Tools and criteria to evaluate the comparability of corpora
 * Parallel vs non-parallel corpora, monolingual corpora
 * Rare and minority languages
 * Across language families
 * Multi-media/multi-modal comparable corpora

Applications of comparable corpora:

 * Human translations
 * Language learning
 * Cross-language information retrieval & document categorization
 * Bilingual projections
 * Machine translation
 * Writing assistance

Mining from Comparable Corpora:

 * Extraction of parallel segments or paraphrases from comparable
 * Extraction of bilingual and multilingual translations of single
   words and multi-word expressions; proper names, named entities,

       26 May 2012    Workshop date


Papers should follow the LREC main conference formatting details (to be
announced on the conference website
and should be submitted as a PDF-file of no more than ten pages via the
START workshop manager:
Reviewing will be double blind, so the papers should not reveal the
authors' identity. Accepted papers will be published in the workshop

Double submission policy: Parallel submission to other meetings or
publications are possible but must be immediately notified to the
workshop organizers.

When submitting a paper through the START page, authors will be asked to
provide information about the resources that have been used for the work
described in their paper or are an outcome of their research. For
details on this initiative, please refer to  Authors will also be
asked to contribute to the Language Library, the new initiative of LREC
