hfst-unweighted2weighted

Purpose

Transform an unweighted transducer to a weighted one. All weights are initialised to zero (in the tropical semiring).

Usage

hfst-unweighted2weighted [OPTIONS...] [INFILE]

Parameters

Parameters common for all commandline programs.

-h, --help Print help message
-V, --version Print version info
-v, --verbose Print verbosely while processing
-q, --quiet Do not print output
-s, --silent Alias of --quiet

Parameters common for all commandline programs taking one input stream and writing transducers or text as output.

-i, --input=FILENAME Read input from FILENAME
-o, --output=FILENAME Write output to FILENAME

Details

The input is read one transducer at a time. Each input transducer is transformed to a transducer in text format. The transducer in text format is transformed again to a binary transducer (a zero-weighted weighted one). This transducer is written to the output.

The input

The input may either come from a file or STDIN (depending on, if the parameter input is used or not). In both cases the input consists of unweighted transducers.

The output

The output may either be written to a file or STDOUT (depending on, if the parameter output is used or not). In both cases the output consists of weighted transducers written one after another.

Installing

The program is distributed with a Makefile. Calling make install will create all HFST command line tools, including hfst-unweighted2weighted.

Obtaining the program

The program may be obtained from the CVS-repository on the server corpus.csc.fi.
