Introduction

BOLT Egyptian-English Word Alignment -- Discussion Forum Training was developed by the Linguistic Data Consortium (LDC) and consists of 400,448 words of Egyptian Arabic 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 Egyptian 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 Arabic Discussion Forums (LDC2018T10).

The BOLT word alignment task was built on treebank annotation. Specifically, Egyptian source tree tokens for word alignment were automatically extracted from tree files of BOLT Egyptian Arabic Treebank annotation on the source discussion forum data harvested by LDC. Human annotators then followed LDC guidelines to link words and phrases in Arabic to those in English.

The data profile broken down by character tokens, tree tokens and segments appears below:
