Introduction
BOLT Chinese-English Word Alignment and Tagging -- Discussion Forum Training was developed by the Linguistic Data Consortium (LDC) and consists of 448,094 words of Chinese and English parallel text enhanced with linguistic tags to indicate word relations.
The DARPA BOLT (Broad Operational Language Translation) program developed machine translation and information retrieval for less formal genres, focusing particularly on user-generated content. LDC supported the BOLT program by collecting informal data sources -- discussion forums, text messaging and chat -- in Chinese, Egyptian Arabic and English. The collected data was translated and annotated for various tasks including word alignment, treebanking, propbanking and co-reference.
Data
This release consists of Chinese source discussion forum threads harvested from the Internet by LDC using a combination of manual and automatic processes. The source data is released as BOLT Chinese Discussion Forums (LDC2016T05).
The BOLT word alignment task was built on treebank annotation. Specifically, LDC automatically extracted Chinese source tokens, including empty categories/traces, from word-segmented files provided by the BOLT Chinese Treebank annotation team at Brandeis University. The word-segmented tokens were then used to automatically generate ctb (Chinese Treebank) alignment and were also tokenized for character alignment by inserting white spaces to separate characters.
The data profile broken down by character tokens, ctb tokens and segments appears below:
| Language | Genre | Files | Words | CharTokens | CTBTokens | Segments |
| Chinese | forum | 570 | 448,094 | 672,140 | 442,520 | 20,819 |
