NAME
hfst-strings2fst - =Compile string pairs and pair-strings into trans‐
ducer(s)
SYNOPSIS
hfst-strings2fst [OPTIONS...] [INFILE]
DESCRIPTION
Compile string pairs and pair-strings into transducer(s)
Common options:
-h, --help
Print help message
-V, --version
Print version info
-v, --verbose
Print verbosely while processing
-q, --quiet
Only print fatal erros and requested output
-s, --silent
Alias of --quiet
Input/Output options:
-i, --input=INFILE
Read input strings from INFILE
-o, --output=OUTFILE
Write output transducer to OUTFILE
String and format options:
-f, --format=FMT
Write result in FMT format
-j, --disjunct-strings
Disjunct all strings instead of transforming each string into a
separate transducer
--norm Divide each weight by sum of all weights (with option -j)
--log Take negative natural logarithm of each weight
--log10
Take negative 10-based logarithm of each weight
-p, --pairstrings
Input is in pairstring format
-S, --has-spaces
Input has spaces between symbols/symbol pairs
-e, --epsilon=EPS
Interpret string EPS as epsilon.
-m, --multichar-symbols=FILE
Strings that must be tokenized as one symbol.
If OUTFILE or INFILE is missing or -, standard streams will be used.
FMT can be { foma, openfst-tropical, openfst-log, sfst, opti‐
mized-lookup-weighted, optimized-lookup-unweighted }. If EPS is not
defined, the default representation of @0@ is used. Option --norm pre‐
cedes option --log. The FILE of option -m lists all multichar-symbols,
each symbol on its own line. Backslash '\' may be used to escape ':',
tab and itself. For any other symbol x '\x' means x literally, i.e. is
the same as 'x'. The weight of a string can be given after the string
separated by a tabulator. The weight cannot be zero.
EXAMPLES
echo "cat:dog" | hfst-strings2fst
create cat:dog fst
echo "c:da:ot:g" | hfst-strings2fst -p
same as pairstring
echo "c:d a:o t:g" | hfst-strings2fst -p -S
same as pairstring with spaces
echo "c a t:d o g" | hfst-strings2fst -S
same with spaces
