NAME

       fst-train - learning transducer weights

SYNOPSIS

       fst-train [ options ] file [ input-file ]

OPTIONS

       -t file
	      use multiple transducers in the same way as fst-infl2.

       -b     This option is used for supervised training with disambiguated data.

       -d     Disambiguate the analyses symbolically as described in the man pages of fst-infl2.

       -q     quiet mode

DESCRIPTION

       fst-train  is  used  to	learn  statistical weights for the transducers transitions based on training data. Training is either unsupervised
       (default) or supervised (option -b).
       In supervised mode, the input contains fully disambiguated data with the surface and the analysis form. The format restrictions are identi-
       cal to those applying for lexicon entries, i.e. all operators other than the colon operator (:) are interpreted literally.
       In unsupervised mode, the input data consists of surface strings. The format is identical to the input format of fst-infl and fst-infl2.
       The transducer weights are stored in files whose names are obtained by appending .prob to the names of the transducer files.

BUGS

       No bugs are known so far.

NAME

       fst-mor - Interactive morphological analyser and generator

SYNOPSIS

       fst-mor [options] file

OPTIONS

       -n     Print multi-character symbols without the enclosing angle brackets.

       -h     Print usage information.

DESCRIPTION

       fst-mor	is  an	interactive  morphological  analyser and generator. The argument is the name of a file which was generated by fst-compiler
       (without using option -c).

       fst-mor reads the transducer which is stored in the argument file and prompts the user for input. Each input line is  processed	until  the
       user enters "q" which ends the program.

       fst-mor has two modes, an analysis mode (default) and a generation mode.  Entering an empty input line switches between the two modes.

       In order to explain what the program does in generation and analysis, consider the following transducer:

	      a b:x c:<> d

       In  generation mode, the program will print "axd" if the user enters "abcd" and "no result" otherwise. In other words, the program maps the
       left symbols to the right symbols of the transducer.

       In analysis mode, the program will print "abcd" if the user enters "axd" and "no result" otherwise.

BUGS

       No bugs are known so far.
