- -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.
- Print surface and analysis symbols. (fst-infl2 only)
- Print multi-character symbols without the enclosing angle
brackets. (fst-infl only)
- 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)
- Print the probability of each analysis. (fst-infl2
- 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)
- Suppress status messages.
- Print usage information.
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.
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
from fst-infl and usually much faster.
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
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
No bugs are known so far.
