accept_check — Check whether a grammar accept / reject given word sequences
accept_check [-t] [-s spname] [-v] {prefix}
accept_check is a tool to check whether a sentence can be accepted or
rejected on a grammar (prefix.dfa and
prefix.dict). The sentence should be given from
standard input. You can do a batch check by preparing all test
sentence at each line of a text file, and give it as standard input of
accept_check.
This tool needs .dfa, .dict and .term files. You should convert a written grammar file to generate them by mkdfa.pl.
A sentence should be given as space-separated word sequence.
It may be required to add head / tail silence word like sil,
depending on your grammar. And should not contain a short-pause word.
When a word belongs to various category in a grammar, accept_check will check all the possible sentence patterns, and accept it if any of those is acceptable.
-t
Use category name as input instead of word.
-s
spname
Short-pause word name to be skipped.
(default: "sp")
-v
Debug output.
