I think this is a very interesting version/alternative to the page rank system that we talked about in class. This search engine attempts to understand the keywords and make sense of what exactly is happening on a website and use that in determining the rank of a page. This is different from Google who mostly count links and keywords. If a company was actually 100% able to understand the how they keywords were used and how they were related to each other, I think that a very strong and accurate search engine could be developed with a solid algorithm, possibly more advanced than Google's.
