Blog Categorisation using Encog, ROME, JSoup and Google Guava

Continuing with Programming Collection Intelligence  (PCI) the next exercise was using the distance scores to pigeonhole a list of blogs based on the words used within the relevant blog.

I had already found Encog as the framework for the AI / Machine learning algorithms, for this exercise I needed an RSS reader and a HTML parser.
The 2 libraries I ended up using were:
ROME
JSoup

For general other utilities and collection manipulations I used:
Google Guava

I kept the list of blogs short, included some of the software bloggers I follow, just to make testing quick, had to alter the %'s a little from the implementation in (PCI), but still got the desired result.

Blogs Used:

For the implementation I just went with a main class and a reader class:
