TD*IDF analysis Tools

[jayoliverwright]

Hi guys,

I was wondering if anyone knew of free TD*IDF analysis tools on the market?

I know about onpage.org and Text-tools.net both paid.

I was wondering if anyone knows of other tools?

Cheers,

Chris

Hi Chris,

It's not the TD-IDF solution you're after but may help? SEO Quake (available as a free Chrome plug-in: https://chrome.google.com/webstore/detail/seoquake/akdgnmcogleenhbclghghlkkdndkjdjc) approximates some of this data for you.

It will show the most commonly recurring 1, 2, 3 and 4 word phrases appearing on a web page. It won't compare this to a corpus (e.g. your whole site). It then gives a Density % (broadly, how often this word/phrase appears) and a Prominence % (based around density but also where it appears: title, description, keywords etc.).

Hope that helps.

Hi Chris,

I don't know of any free tools that do this unless you want to write some code yourself.  If you go that route we have some open source libraries that you might find useful, especially qdr that implements the TF-IDF scoring and dragnet for parsing/cleaning the HTML.  Good luck in your search!
