Semantic Web & Calais

I spotted a semantic web product called Calais a while back on (Reuters Wants The World To Be Tagged). Basically, it takes any document and 'marks it up' with various semantic web tags. I didn't give it much thought till a blog post this morning Reuters Launches Calais 2.0 - Now With Pop-Culture which reports support for the pharmaceutical and medical world.

You can use this Calais Viewer link to try it out.

I enjoyed using it, but it still has a long way to go, the number of terms it recognises is limited.

Given my lack of vision I'm not sure how you can utilise knowing that ibuprofen is a 'product' and feverish illness is a 'medical condition'. Perhaps one day it'll become obvious...
