Software - Development

I want a program that queries the worlds blogs, and possibly websites every 10 minutes for recent posts, ? once it has queried the blogs and websites, it presents the info in order of country, in a percentage form. lets say it checks 1000 blogs in India, all the posts being on a variety of topics, it then shows me on the website that 10% of posts in India were about poverty, 20% about the film industry etc. It will also be categorized in order of genders, so it would be able to tell that 20% of posts in India were made my males or females, this is done by taking the users username from the blog, and then checking for a profile name with that username. So it would check the worlds blogs and websites not just the ones used in my example which is India. I need both the software and a interface for this developed.
