### Introduction

BOLT Chinese SMS/Chat was developed by the Linguistic Data Consortium
(LDC) and consists of naturally-occurring Short Message Service (SMS)
and Chat (CHT) data collected through data donations and live collection
involving native speakers of Chinese. The corpus contains 14,877
conversations totaling 3,005,810 words across 497,543 messages.

The
[BOLT](https://www.ldc.upenn.edu/collaborations/current-projects/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

The data in this release was collected using two methods: new collection
via LDC's collection platform, and donation of SMS or chat archives from
BOLT collection participants. All data collected were reviewed manually
to exclude any messages/conversations that were not in the target
language or that had sensitive content, such as personal identifying
information (PII). All data is presented in UTF-8 XML.
