Welcome

What is NACLO?

NACLO (North American Computational Linguistics Open Competition) is a national competition for students in grades 6-12. You’ll get to solve puzzles about language for a chance to win a spot to represent the US in the International Linguistics Olympiad. No prior knowledge of linguistics or a second language is necessary!

What is computational linguistics?

Computational linguistics (or CL) is the science of understanding human language using logic, computer algorithms, and math. It is all around us! You use CL whenever you use Google, Facebook, Twitter, Microsoft, Yahoo, and many other websites and applications. Here are some examples of computational linguistics in action.
