DEFT Narrative Text was developed by the Linguistic Data Consortium (LDC) and contains proxy reports and their source newswire used to support DARPA's Deep Exploration and Filtering of Text (DEFT) program. Among the goals of the DEFT program is to develop technologies that can perform various NLP tasks on data in a variety of genres, both formal and informal.

LDC provided source data and annotations for DEFT system development. DEFT Narrative Text consists of "proxy reports" (and "multi-proxy reports") in English. (Multi-)proxy reports are intended to mimic the format and other features of some types of government analyst reports using content from newswire articles. The corresponding English newswire source documents are also included in the release.


LDC staff manually selected the source newswire from English Gigaword Fifth Edition (LDC2011T07). Articles were selected for topics of potential interest to the intelligence community based on general guidance from DEFT project sponsors.

The newswire source documents are XML files following the Gigaword corpus format. The proxy reports are in plain text format.
