IXDOMAIN(1)IXDOMAIN(1)NAMEixdomain - convert weighting domain files
SYNOPSIS
/usr/bin/ixdomain [ -dhwDH ] [ file ... ]
DESCRIPTION
Notice: ixdomain is now obsolete. Its functionality is provided by the
more general program ixparse(1).
ixdomain converts weighting domain files between three different
formats. Weighting domains can be converted between domain format as
defined by the IXWeightingDomain class of the Indexing Kit, histogram
format, and NEXTSTEP Release 2 word frequency table (WFTable) format.
Domain format files are preferred for use with ixbuild(1).
Each line of a file in histogram format has the form:
token weight rank
Where token is the token or word in the index, weight is its weight
(frequency) in the domain, and rank is its cardinal rank in the domain
(1 == most common, 2 = second most common, and so on). The fields of
the line are separated by single spaces; be sure to search backward
from the end of a line to find the token, as it is possible for it to
contain embedded spaces or tabs.
OPTIONS-- Lists these options.
-d Reads domain format.
-h Reads histogram format (default).
-w Reads WFTable format.
-D Writes domain format (default).
-H Writes histogram format.
