The Penn - CU Chinese Treebank Project
Growing interest in Chinese Language Processing is leading to the development
of resources such as annotated corpora and automatic segmenters, part-of-speech
taggers and parsers.
Currently these are all being developed independently,
often with quite different standards for segmentation, part-of-speech tagging
and syntactic bracketing.
The time is ripe for an open discussion of the
methodological issues involved in achieving agreement on annotation
standards.
Unlike Western and Middle Eastern
Writing systems, Chinese writing does not have a
natural delimiter between words with the result that appropriate word
segmentation becomes a prerequisite for any other NLP tasks. In the literature
this problem has been discussed extensively.
The problem of part-of-speech
tagging is closely related.
These are both prerequisites to the establishment
of a Chinese Treebank that could be of general use.
We have completed building a 780K-thousand-word Chinese Treebank.
Our aim is to work towards a community
consensus on guidelines that will include the input of influential researchers
from Taiwan, Singapore, Hong Kong, China and the US.
To this end,
we held two workshops and a number of meetings between 7/1998 to 10/2000
in USA and abroad.
We are very interested in the community's
reaction to our guidelines and Treebank, and encourage anyone interested in
getting involved to please look into the guidelines we have attached below, use
the Treebank, which is available via , and
to get in touch with us with your comments.
Descriptions of the project:
Task: Building a segmented, POS tagged and bracketed Chinese corpus. The
data consists of Xinhua newswire, Hong Kong news and articles from Sinorama
news magazine. There is on-going effort to annotate broadcast news and broadcast
conversation data under the
DARPA GALE funding.
Latest release: The Chinese TreeBank (CTB) version 6.0, which has
has been officially
released via .
CTB6.0 data composition:
Xinhua newswire:
[001-325, 400-454, 600-885, 900-931]
Hong Kong news: [500-554]
Sinorama: [590-596, ], Broadcast news: []
for more information.
Coming soon! CTB6.0 is in the LDC publication pipeline.
Penn guidelines for Chinese Treebank
Segmentation guidelines (final version):
Guideline for POS tagging (final version):
Guideline for Bracketing (final version):
All three guidelines are now
technical reports. The ID numbers are
00-06, 00-07 and 00-08, respectively.
