What is unique content to Google

I think Google probably can only recognize patterns and large amounts of text. In a past life, I created several search engine robots, and I can tell you that it is a very hard task even with very complex math to determine word proximities in large quantities. To determine patterns in sentences would be ridiculous. You really need a combination of many sentences in order to determine a large pattern. So I don't think Google is looking at small amounts of text. You have to have patterns in large blocks, if at all.

Another interesting question is who is the originator of the content. If I have a web site with 100,000 incoming links am I the authoritative source of the information. Versus the originator of the information who only has 10,000 incoming links. It's an interesting question. What is the criteria for being the originator?

With a simple program like ArticleBot. I think you can create many variations of original content, and they would all appear unique.
