BYU North American Computational Linguistics Open Competition 2020

The overall organization

NACLO is an abbreviation for the North American Computational Linguistics Open Competition. It is a fun and educational contest for high school (and younger) students that has them solve linguistics problems drawn from a variety of languages (natural and artificial). Though no prior knowledge of particular languages or of linguistics is required, a good knowledge of logic, reasoning, and problem solving skills is helpful.

The first round of NACLO competition is held locally at various locations in the U.S. and Canada. Students who score well on the test advance to a second invitational round of competition.

The Computational Linguistics Open Competition is a worldwide movement which began in Moscow in the 1960's. The U.S. first entered the competition in 1998. Teams from many other places of the world, including a team of top-scoring students from the U.S. NACLO, compete in the worldwide championship.

Last year

In 2019 some 1,500 high school students from across the USA and Canada competed in the annual North American Computational Linguistics Open Competition. The 2019 competions featured problems about Maltese, Ndebele, Catio, Lopit, Mongolian, Hanunó'o, Witsuwit’en, Mayangna, Vietnamese, Afrihili, Róng, Sranan Tongo, Polish, as well as computational topics, such as synchronic Begriffsschrift formulas, natural language inference, disambiguation, and character-level language modeling. The top 152 students (roughly 10% of all participants) advanced to the invitational round, a more difficult five-hour test. The top eight NACLO winners from the U.S. advanced to the International Olympiad of Linguistics, held in Yongin, South Korea.
