% of different content types out there on the web

(sorry for the cross post)

Hey Guys,

I'm trying to find a good citation or estimate (if anyone has done one) that estimates
the breakout (by % or some other metric) of content types out there out the web
(with a whole web crawl or a meaningful representative dataset) that are non HTML.

Anyone have any ideas about this?

Thanks!

Cheers,
Chris

Unfortunately no, we don't keep record of those, just filter them away as soon 
as wel can.

Hi Markus,

Thanks for the FYI. Any idea at specific %'s for those unwanted suffixes compared
to the size of the entire corpus?

Cheers,
Chris

Hello Chris,

In the Portuguese Web Archive we did a study of web characteristics
for the portuguese web. I don't know if this helps you but where is
the papper.

João Miranda, Daniel Gomes, Trends in Web characteristics (best paper
award: 2nd place), 7th Latin American Web Congress, Merida, Mexico,
November 2009
Link to the papper:
http://sobre.arquivo.pt/sobre-o-arquivo/trends-in-web-characteristics/at_download/file
Presentation: http://sobre.arquivo.pt/about-the-archive/presentation-trends-in-web-characteristics
About other publications from our archive:

Hope this is of assistence.
Cheers,

That could be an interesting experiment to do with the commoncrawl dataset
and Tika on Behemoth. Assuming of course that the detection is done
correctly by Tika.  Does anyone have a spare cluster on EC2 ;-) ?

We only crawl HTML and PDF files for a lot of cc-TLD's so we only have data on 
those two. However, we also explicitly filter out all/most unwanted suffixes. 
We do have a lot of suffixes that we encountered so far.
