=head1 NAME
tmx-POStagger - POStaggers translation units on a tmx file.
=head1 VERSION
version 0.39
=head1 SYNOPSIS
tmx-POStagger file.tmx # creates pos_file.tmx
tmx-POStagger -o=out.tmx file.tmx
-ner ... tags multiword named entities
-dates
-compact
=head1 DESCRIPTION
Although this script is bundled in C<XML::TMX>, it has a soft
dependency on C<Lingua::FreeLing3>. Soft means that the dependency is
not ensured at install time, and other features of the module can
still be used without C<Lingua::FreeLing3>. Nevertheless, if you want
to use this tool you should install that module.
At the moment the supported languages are the same as supported by
FreeLing3: English, Spanish, Russian, Portuguese and Italian.
It your TMX file includes any other language, they will be maintained
without a change. This behavior can change in the future, as a basic
regexp based POStaggerr might be implemented.
=head2 Options
-ner -- groups Proper names with tag C<mwe>
which which WDT
includes include VBZ
<mwe lema="edward_cole" pos="NP00000">
Edward
Cole
</mwe>
-compact
-dates
