How To Advance In the North American Computational Linguistics Olympiad

Computational Linguistics is an interdisciplinary field that uses computers to process and analyze human language. This rapidly growing field has numerous applications in various industries. The North American Computational Linguistics Olympiad (NACLO) is an annual competition to inspire high school students to pursue Computational Linguistics and related fields.

What is the North American Computational Linguistics Olympiad? A Quick Look

NACLO is a contest where high school students solve linguistic problems, enhancing their logic skills and understanding of language diversity and consistency. No prior knowledge of linguistics or second languages is needed. 

Experts in linguistics and computational language technologies create problems using various languages, reflecting current field issues. The competition attracts top students to pursue studies and careers in these areas, offering them a glimpse into 21st-century natural-language processing.

NACLO, first held in 2006, has grown into a popular competition with thousands of high school students from North America participating each year. It is organized by dedicated volunteers, including university professors, high school teachers, and industry professionals. They create challenging problems that test students’ skills in areas like syntax, morphology, semantics, and pragmatics.

Participating in NACLO is a fantastic way for high school students to explore their interest in Computational Linguistics and related fields. The problems are designed to be tough but also accessible, even if you have no prior experience. NACLO offers a fun and engaging way to learn about the field and its applications.

NACLO also allows students to compete with their peers and showcase their skills. The competition is well-respected by universities and industry professionals, and top-performing students can earn recognition and prizes. Besides the competition, NACLO supports teachers who want to introduce computational linguistics to their classrooms. They offer training materials, sample problems, and online resources to help teach these concepts.

How to Qualify for the North American Computational Linguistics Olympiad

To qualify for the North American Computational Linguistics Olympiad (NACLO), high school students must start by taking the Open Round. This is a 3-hour online test open to any high school student, typically held in January or February. Students can register for the test on the NACLO website.

The Open Round features linguistics problems in areas like syntax, morphology, semantics, and pragmatics. These problems are challenging but designed to be accessible, even for students without prior experience.

Top performers from the Open Round are invited to the Invitational Round, a 4.5-hour in-person test held at various locations across North America. This round includes more advanced linguistics problems.

The best students from the Invitational Round can qualify for the International Linguistics Olympiad (ILO), an annual event held in different countries. The ILO brings together top students from around the world to compete in linguistics problem-solving.

There are three rounds in total for the North American Computational Linguistics Olympiad:

  • Open Round: The initial 3-hour online test is open to all high school students.
  • Invitational Round: A 4.5-hour in-person test for top performers from the Open Round.
  • International Linguistics Olympiad (ILO): The final round for top performers from the Invitational Round, held annually in different countries.

Open Round

The Open Round is available to all interested middle and high school students. Its purpose is to introduce students to linguistics and computational linguistics while identifying those who will advance to the Invitational Round.

The Open Round will take place on January 25, 2024.

Invitational Round

This round offers a fun and educational challenge with more difficult problems for students who did well in the Open Round. NACLO also uses this round to identify students for the North American teams competing in the International Linguistics Olympiad (IOL), provided they meet IOL eligibility requirements.

If your school is closed for Spring Break on this date, you can participate at a nearby university or secondary school. Check naclo.org for a list of NACLO host sites.
