Introduction

BOLT Information Retrieval Comprehensive Training and Evaluation was developed by the Linguistic Data Consortium (LDC) and consists of all data produced in support of the Information Retrieval (IR) task within the DARPA Broad Operational Language Translation (BOLT) Program, including annotations, source documents and scoring software.

The BOLT program developed machine translation and information retrieval for less formal genres, focusing particularly on user-generated content. LDC supported BOLT 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.

The material in this release relates to the IR task, which sought to support development of systems that could: (1) take as input a natural language English query sentence; (2) return relevant responses to that query from a large corpus of informal documents in the three BOLT languages (Arabic, Chinese, and English); and (3) translate responses from non-English documents into English.

Data

BOLT Information Retrieval Comprehensive Training and Evaluation contains the pilot, dry run, and evaluation data developed for each phase of the BOLT IR task, including: (1) natural-language IR queries, system responses to queries, and manually-generated assessment judgments for system responses; (2) discussion forum source documents in Arabic, Chinese and English; (3) scoring software for each evaluation phase; and (4) experimental data developed in Phase 2.

Source data is presented as a series of zip archives containing xml files. Queries and responses data are presented as XML as well. Judgments are included as tab delimited files.
