GALE Chinese-English Word Alignment and Tagging Training Part 1 -- Newswire
and Web was developed by the Linguistic Data Consortium (LDC) and contains 150,068 tokens of word aligned
Chinese and English parallel text enriched with linguistic tags. This material
was used as training data in the DARPA
GALE (Global Autonomous Language Exploitation) program.
Some approaches to statistical machine translation include the incorporation
of linguistic knowledge in word aligned text as a means to improve automatic
word alignment and machine translation quality. This is accomplished with two
annotation schemes: alignment and tagging. Alignment identifies minimum translation
units and translation relations by using minimum-match and attachment annotation
approaches. A set of word tags and alignment link tags are designed in the tagging
scheme to describe these translation units and relations. Tagging adds contextual,
syntactic and language-specific features to the alignment annotation.
This release consists of Chinese source newswire and web data (newsgroup, weblog)
collected by LDC in 2008. The distribution by genre, words, character tokens
and segments appears below:
|Chinese|| wb || 87|| 46766 || 70149 || 2357
Note that all token counts are based on the Chinese data only. One token is equivalent
to one character and one word is equivalent to 1.5 characters.
The Chinese word alignment tasks consisted of the following components:
- Identifying, aligning, and tagging 8 different types of links
- Identifying, attaching, and tagging local-level unmatched words
- Identifying and tagging sentence/discourse-level unmatched words
- Identifying and tagging all instances of Chinese 的 (DE) except when
they were a part of a semantic link.
The file names indicate the source provider, the story date and the language.
For example, "AFP_CMN_20080406"" refers to the source Agence France Presse ("AFP"),
the story date is April 6, 2008 and the language is Chinese ("CMN").
Please follow the links for the source, translation, and
word alignment files.
