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 keywords

DESCRIPTION

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.
