Universal Dependencies - English Dependency Treebank | ||
Universal Dependencies English Web Treebank v2.7 -- 2020-11-15 | ||
https://github.com/UniversalDependencies/UD_English-EWT | ||
|
||
|
||
# Summary | ||
|
||
A Gold Standard Universal Dependencies Corpus for English, | ||
built over the source material of the English Web Treebank | ||
LDC2012T13 (https://catalog.ldc.upenn.edu/LDC2012T13). | ||
|
||
|
||
# Introduction | ||
|
||
The corpus comprises 254,830 words and 16,622 sentences, taken from five genres | ||
of web media: weblogs, newsgroups, emails, reviews, and Yahoo! answers. See the | ||
LDC2012T13 documentation for more details on the sources of the sentences. The | ||
trees were automatically converted into Stanford Dependencies and then | ||
hand-corrected to Universal Dependencies. All the basic dependency annotations have | ||
been single-annotated, a limited portion of them have been double-annotated, | ||
and subsequent correction has been done to improve consistency. Other aspects | ||
of the treebank, such as Universal POS, features and enhanced dependencies, has | ||
mainly been done automatically, with very limited hand-correction. | ||

# Structure | ||
|
||
This directory contains a corpus of sentences annotated using Universal | ||
Dependencies annotation. The corpus comprises 254,830 words and 16,622 | ||
sentences, taken from various web media including weblogs, newsgroups, emails, | ||
reviews, and Yahoo! answers; see the LDC2012T13 documentation for more details | ||
on the source of the sentences. The trees were automatically converted into | ||
Stanford Dependencies and then hand-corrected to Universal Dependencies. All | ||
the dependency annotations have been single-annotated, and a limited portion of | ||
them have been double-annotated with interannotator agreement at approximately | ||
96%. The sentence IDs include the genre and the filename | ||
of the original LDC2012T13 filename. | ||
|
||
This corpus is compatible with the CoNLL-U format defined for Universal | ||
Dependencies. See: | ||
|
||
http://universaldependencies.github.io/docs/format.html | ||
|
||
The dependency taxonomy can be found on the Universal Dependencies web site: | ||
|
||
http://www.universaldependencies.org | ||
|
||
For the conversion to v2, we performed an automatic conversion with extensive | ||
spot-checking, and manual adjudication of ambiguous cases. | ||
|
||
The enhanced dependencies were automatically obtained by running an adapted version | ||
of the converter by Schuster and Manning (2016). These dependencies have **not** been | ||
manually checked. | ||
|
||
# Deviations from UD | ||
|
||
Version 2.7 of the English UD treebank conforms to the UD guidelines in | ||
almost all respects, but there remain the following deviations: | ||
|
||
- The UD dependency `flat` is largely only used for person names. | ||
- Dates are not annotated consistently. | ||
- The attachment of punctuation tokens is sometimes not according to the | ||
guidelines. | ||
|
||
