Installation

If you exist on the ÚFAL network, you can use directly Dan's version here. Otherwise, you need to ask Dan for a zipped package of the currently existing drivers. (I intend to maintain it here for download some time later.) Unzip it to a convenient place; below, we assume it is in /home/zeman/lib/perl.

Contributions welcome! If you write your own driver, please share it with others! If you send it to me, I will add it to the package for download here.

Existing drivers

How to use the Interset

You can write your own tag conversion Perl script, and use the Interset driver library. You have to tell Perl where to find the drivers:

setenv PERLLIB /home/zeman/lib/perl:$PERLLIB

Once the variable is set, writing a conversion script is very easy. For instance, my csts-cs-pdt-en-penn.pl script (meaning “read and write CSTS format, read Czech PDT tags, write English Penn tags) essentially looks like this:

use tagset::cs::pdt;
use tagset::en::penn;
 
while(<>)
{
    if(s/<t>([^<]+)/<_tag_to_convert_>)
    {
        my $tag0 = $1;
        my $features = tagset::cs::pdt::decode($tag0);
        my $tag1 = tagset::en::penn::encode($features);
        s/<_tag_to_convert_>/<t>$tag1/;
    }
    print;
}

Note the two-step replacement of the original tag. I do not dare to use the original tag in a regular expression because there could be special characters in the tag.
