The Stanford Parser is neat

The Stanford Parser: A statistical parser is a pretty neat piece of GPL java code does all kinds of wild text processing.

It can parse a sentence and create a dependency graph that relates each word and includes POS-tagging. Gadzooks!

I had to change the script to use 512m instead of 150m to process even pretty small files…
