NAME
Lingua::ZH::Keywords - Extract keywords from Chinese text
SYNOPSIS
# Exports keywords() by default
use Lingua::ZH::Keywords;
print join(",", keywords($text)); # Prints five keywords
print join(",", keywords($text, 10)); # Prints ten keywordsDESCRIPTION
This is a very simple algorithm which removes stopwords from the text, and then counts up what it considers to be the most important keywords. The keywords subroutine returns a list of keywords in order of relevance.
The stopwords list is accessible as @Lingua::ZH::Keywords::StopWords.
If the input $text is an Unicode string, the returned keywords will also be Unicode strings; otherwise they are assumed to be Big5-encoded bytestrings.
