Opencalais is one of those Web 3.0 (sorry) services which is really rather interesting. Basically if you throw plain text at it will return the concepts it finds. For example it would recognise the Royal Albert Hall as a place and London as a city. The output is in RDF, yay.

As you might have guessed I’m thwacking the data from iPlayerlist (which is essentially bbc.co.uk/programmes) through it and see what we get.

Well its made me giggle. You get some cool stuff like programmes relating to Cities, People and Nations, but also some rather random topics. Medical Conditions is my favorite, you would be surprised how many programmes pop up in that topic.

So keep you eye out, it won’t be long before you will be able to subscribe to iPlayer shows relating to “sore throats” :)
