This isn't my plugin, but I came across this today, and found it handy: http://www.hovinne.com/blog/index.php/2007/08/09/135-jquery-wordstats-plugin
>From the site itself: The jQuery wordStats plugin tries to determine what a page is about by computing the density of its keywords. It uses a simple algorithm which adds a variable weight for each keyword occurrence, depending on its 'position' in the document. Although this computation model is quite simple, I get good results with all sorts of documents. There's of course a system to exclude 'stop words' (frequent pronouns, prepositions, adverbs and so on). -- Tane Piper http://digitalspaghetti.me.uk This email is: [ ] blogable [ x ] ask first [ ] private
