NAME¶

lt-trim — compiled dictionary trimmer for Apertium

SYNOPSIS¶

DESCRIPTION¶

lt-trim is the application responsible for trimming compiled dictionaries. The analyses (right-side when compiling lr) of analyser_binary are trimmed to the input side of bidix_binary (left-side when compiling lr, right-side when compiling rl), such that only analyses which would pass through ‘lt-proc(1) -b bidix_binary’ are kept.

Warning: this program is experimental! It has been tested, but not deployed extensively yet.

Both compound tags (“<compound-only-L>”, “<compound-R>”) and join elements (“<j/>” in XML, “+” in the stream) and the group element (“<g/>” in XML, “#” in the stream) should be handled correctly, even combinations of + followed by # in monodix are handled.

Some minor caveats: If you have the capitalised lemma “Foo” in the monodix, but “foo” in the bidix, an analysis “^Foo<tag>$” would pass through bidix when doing lt-proc(1) -b, but will not make it through trimming. Make sure your lemmas have the same capitalisation in the different dictionaries. Also, you should not have literal ‘+’ or ‘#’ in your lemmas. Since lt-comp(1) doesn't escape these, lt-trim cannot know that they are different from “<j/>” or “<g/>”, and you may get @-marked output this way. You can analyse ‘+’ or ‘#’ by having the literal symbol in the “<l>” part and some other string (e.g., “plus”) in the “<r>”.

You should not trim a generator unless you have a very simple translator pipeline, since the output of bidix seldom goes unchanged through transfer.
