Thanks for the info, but i do not think it is STT2 because STT2 provides internal linking, whereas this site provides external links. Anyone else with a better suggestion?

It look cosaaranda trick.. using generated auto content...

like this Code

<?php
$gac = generateAutoContent(get_the_title(), false, true, false, 5);
echo outputAutoContent($gac,'<p><a
href="http://www.ukcop.net/search/[[permalink]]">[[keyword]]</a><br />[[description]]<br /><small>Source: [[source]]</small></p>',5);
?>
