      "Putting a Value on Comparable Data"



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.

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. Interest in
non-parallel forms of comparable corpora in language engineering
primarily ensued from the scarcity of parallel corpora. This 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.

With the advent of online data, the potential for building and
exploring comparable corpora is growing exponentially. Comparable
documents in languages that are very different from each other
pose special challenges as very often, the non-parallelness in
sentences can result from cultural and political differences.


The theme of the workshop will be "Comparable Corpora and the
Web". Nevertheless we solicit contributions to other topics as well,
including the following:

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,
