I'm always fascinated with NLP. My undergrad works around it. And currently doing a research for my MS degree. It's about a variant of automatic summarization, wherein I extract the most important sentences in an article. I'll open an API for it soon. :) If you're interested, just contact me in my email (check my profile for it).

In the meantime, here's a preview of what it can do. http://goo.gl/Lz7Vr
