Reddit reviews Natural Language Processing for Prolog Programmers

If you're interested in natural language processing, learning Prolog would be a great start. It's very different from most other languages, but its structure makes tokenizing, tagging, parsing, etc. super simple once you get comfortable with it. I used this book to learn Prolog in a class. It's written by a computational linguist (Covington). He also has another book specifically about NLP, but it is out of print and thus quite expensive.
