You can also do this by utilizing the entity extraction/categorization
provided by
online Linked-data/clustering providers. One such service is OpenCalais
provided by Thomson-Reuters.

I had played around with Calais one year back and found it very useful
to learn about Linked-data and entity extraction.

In fact, there is an already existing news clustering service written
on top of OpenCalais.

http://www.opencalais.com/applications/interceder

Klezio.com was also a very good example of this, but now it seems
to be down.

In fact I cooked up an application to pull out the cost of mobile
phones using Opencalais and demoed it in a BangPypers meeting
some time back, here is an archive of it.
