DESCRIPTION

This module was created with reference to Text::MeCab. Text::CaboCha gives you a more natural, Perl-ish way to access libcabocha!

PERFORMANCE

You can get to the result of running eg/benchmark.pl.

$tree = $parser->parse_from_node(Text::MeCab::Node)

Parses the given Text::MeCab::Node via CaboCha::Parser, and returns a Text::CaboCha::Tree object.

$version = Text::CaboCha::version()

The version number, as returned by libcabocha's CaboCha::Parser::version()
