NAME
       fst-infl	fst-infl2 fst-infl3 - morphological analysers

SYNOPSIS
       fst-infl	[ options ] file [ input-file [	output-file ] ]
       fst-infl2 [ options ] file [ input-file [ output-file ] ]
       fst-infl3 [ options ] file [ input-file [ output-file ] ]

OPTIONS
       -t file
	      Read  an alternative transducer from file	and use	it if the main
	      transducer fails to find an analysis. By iterating this  option,
	      a	cascade	of transducers may be tried to find an analysis.

       -b     Print surface and	analysis symbols. (fst-infl2 only)

       -n     Print multi-character symbols without the	enclosing angle	brack-
	      ets.  (fst-infl only)

       -d     The analyses are symbolically disambiguated  by  returning  only
	      analyses	with  a	 minimal  number of morphemes. This option re-
	      quires that morpheme boundaries are marked with the tag <X>.  If
	      no  <X>  tag  is	found in the analysis string, then the program
	      (basically) counts the number of	multi-character	 symbols  con-
	      sisting  entirely	 of  upper-case	characters and uses this count
	      for disambiguation. The latter heuristic was developed  for  the
	      German SMOR morphology. (This option is only available with fst-
	      infl2 and	fst-infl3.)

       -e n   If no regular analysis is	found, do robust  matching  and	 print
	      analyses	with  up  to n edit errors. The	set of edit operations
	      currently	includes replacement, insertion	and deletion. Each op-
	      eration  has  currently  a  fixed	 error weight of 1. (fst-infl2
	      only)

       -% f   Disambiguates the	analyses statistically	and  prints  the  most
	      likely  analyses with at least f % of the	total probability mass
	      of the analyses. The transducer weights are read from a file ob-
	      tained  by  appending  .prob to the name of the transducer file.
	      The weight files are created with	fst-train.  (fst-infl2 only)

       -p     Print the	probability of each analysis. (fst-infl2 only)

       -c     use this option if the transducer	was  compiled  on  a  computer
	      with  a different	endianness. If you have	a transducer which was
	      compiled on a Sparc computer and you want	to use it  on  a  Pen-
	      tium, you	need to	use this option. (fst-infl2 only)

       -q     Suppress status messages.

       -h     Print usage information.

DESCRIPTION
       fst-infl	is a morphological analyser. The first argument	is the name of
       a file which was	generated by fst-compiler.  The	second argument	is the
       name  of	 the input file. The third argument is the output file.	If the
       third argument is missing, output is directed to	stdout.	 If the	second
       argument	is missing, as well, input is read from	stdin.

       fst-infl2 is similar to fst-infl	but needs a transducer in compact for-
       mat (see	the man	pages for fst-compiler and fst-compact). fst-infl2  is
       implemented differently from fst-infl and usually much faster.

       fst-infl3  is also similar to fst-infl but needs	a transducer in	lowmem
       format (see the man pages for fst-compiler and  fst-lowmem).  fst-infl3
       accesses	 the transducer	on disc	rather than reading it into memory. It
       starts very fast	and needs very little memory, but is slower than  fst-
       infl2.

       fst-infl	 reads	the  transducer	 which is stored in the	argument file.
       Then it reads the input file line by line. Each line is	analysed  with
       the transducer and all resulting	analyses are printed (see also the man
       pages for fst-mor).

BUGS
       No bugs are known so far.
