You could have a look at Lingua::EN::Summarize, (which is what Lingua::EN::Keywords claims to use under the hood, but I couldn't see it in the source...), but this is more useful for large bodies of text. The approach is interesting though - basically splitting the text into sentence 'fragments' and searching for simple statements (X is/was/will/etc. Y). It works best with long paragraphs, cutting them approximately in half in my experience. You may get milage from passing your body text though it before passing to Keywords though.

Cheers, Ben.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
