techniques for finding topically related material in streams of

(detection), and track the reoccurrence of old or new events
(tracking).

This publication contains the TREC (Text REtreival Conference)
Mandarin Corpus used for the Chinese task in TRECs 5-6 and
consists of approximately 170 megabytes of articles drawn from
the People's Daily newspaper (1991-1993) and the Xinhua newswire
(1994-1995) formatted to include TREC document ids. The text is
Mandarin Chinese and is encoded using the GB encoding scheme. The
topics (questions) and relevance judgments (right answers) are
not included in this publication but can be downloaded from the
Data/Non-English section of the TREC web site.

This collection of text was originally gathered by the Linguistic
Data Consortium (LDC), and then adapted by the National Institute
of Standards and Technology (NIST) for use in the TREC Mandarin
evaluation program.
