IntroductionThe HARD 2004 Text Corpus was produced by Linguistic Data Consortium (LDC), catalog number LDC2005T28 and ISBN 1-58563-372-0. This corpus contains source data for the 2004 TREC HARD (High Accuracy Retrieval from Documents) Evaluation. HARD 2004 was a track within the NIST Text REtrieval Conference (TREC), with the objective of achieving high accuracy retrieval from documents by leveraging additional information about the searcher and/or the search context, through techniques like passage retrieval and the use of targeted interaction with the searcher. The current corpus was previously distributed to HARD Participants as LDC2004E30. The topics and annotations that correspond to this release are distributed as LDC2005T29, HARD 2004 Topics and Annotations. This corpus was created with support from the DARPA TIDES Program and LDC.
