Google released hummingbird, and it is cool for structured data, but what about unstructured data? That's where http://samuru.com is looking to change the way people search.
We read a tech crunch article that said humming bird was going to answer all our questions using NLP. It didn't seem to do that, so we said, "let's take the afternoon and put the ability to answer questions in to our search engine."
We did that. Here is the slightly unpolished Alpha of the feature.
Ask some questions like: Why are kittens cute
Why are barns red
Why are gas prices so expensive
Should I buy a house
It won't answer everything, but it will answer a lot.
