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 brackets.  (fst-infl
              only)

       -d     The analyses are symbolically disambiguated  by  returning  only  analyses  with  a
              minimal  number  of  morphemes.  This  option requires 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  consisting
              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 operation 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  obtained 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 Pentium, 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 format (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.
