Natural Language Processing for programmers: part 3 -- World Writable

Previously, I experimented with text generation using context-free grammars, one of the oldest techniques in natural language processing. I'll come back to CFGs in a future post.

A common type of classification is no doubt working on your behalf right this moment: spam filtering.
