 <p>You could also use a free article extraction API, for example:</p> <p><a href="https://www.diffbot.com" rel="nofollow">diffbot.com</a><br> <a href="http://embed.ly/extract" rel="nofollow">embed.ly</a><br> <a href="http://textracto.com" rel="nofollow">textracto.com</a></p> <p>Some of them work quite good, and as I know there are all easy to integrate with Ruby.</p>
