atis3/:

This directory contains the ATIS3 training and December 1993 test
corpora transcriptions, annotations, and documentation.  The
corresponding waveform data is located on Discs 17-2.1 and 17-3.1 in
an identical directory structure.  This directory contains the 
following subdirectories:

doc/ - Directory containing ATIS3 documentation
sp_trn/ - Directory containing ATIS3 training data 
sp_tst/ - Directory containing ATIS3 test data

The data in "sp_trn" is organized in the following directory
and file structure:

sp_trn/<SITE>/<SPKR>/<SCEN>/<FILES>

where,

	SITE := "bbn" | "cmu" | "mit" | "nist" | "sri" (data collection sites)
	SPKR := "001" - "zzz" (3-character base-36 speaker IDs)
	SCEN := "1" - "z" (1-character base-36 scenario-session ID)
	FILES := ATIS3 corpora (see the file, "atis3/doc/fil_spec.doc" for a
                                description of the filenames and types)

The data in "sp_tst" is organized in the following directory
and file structure:

sp_tst/<TEST>/<INST>/<SPKR><SCEN>/<FILES>

where,

	TEST := "nov93" (*December 1993 ATIS benchmark test)
	INST := "initial" | (test transcriptions)
                "prelim" | (pre-adjudicated transcriptions and annotations)
                "final" (post-adjudicated transcriptions and annotations)
	SPKR := "001" - "zzz" (3-character base-36 speaker IDs)
	SCEN := "1" - "z" (1-character base-36 scenario-session ID)
	FILES := ATIS3 corpora (see the file, "atis3/doc/fil_spec.doc" for a
                                description of the filenames and types)

	(Note:  The directory containing the December 1993 test corpora
	was inadvertently named "nov93")

        The waveform files, which are located on Disc 17-3.1, have the
        same directory/file structure, except there is no <INST> directory
        since there is only 1 instantiation of the waveform data.

        In addition, "atis3/sp_tst/nov93", contains documentation and
        a subdirectory, "bug_rpts", which contains copies of requests for 
        adjudication.  See the file, "atis3/sp_tst/nov93/readme.doc" for
        more information about the contents of the "nov93" directory.
