NACLO 2021 - North American Computational Linguistics Open competition

Body

The open round of this year’s NACLO competition will take place on January 27, 2022 Make sure to register at the official site!

 

What is NACLO?

Are you a high school student with a knack for languages, logic and computational thinking? Would you like to try your hand at deciphering an ancient script or deducing the logical patterns of Swahili or Hawaiian?

NACLO stands for the North American Computational Linguistics Olympiad. It is a contest for high-school (and younger) students to solve linguistics problems drawn from a variety of languages. Only logic and reasoning skills are necessary; no prior knowledge of particular languages or of linguistics is required.

This year, Ohio State University will run an in-person site with social distancing!

The open round of the contest will take place on January 27, 2022. Well-performing students will be invited to a second round (March 17). The top students in the invitational round will have a chance to participate in the International Linguistics Olympiad in the summer. More information about NACLO can be found at the national NACLO site.

Registration

Participation is free. Students who are interested in can register at the NACLO registration site. Register early to be assured of a seat. Registrations will still be accepted, provided that space is available, up until January 24.

What can Ohio State do for me?

In addition to running our NACLO site, members of the Linguistics department would be pleased to support your NACLO club, team or study session! We can arrange a Zoom or in-person meeting with a member of our faculty or staff to show you how to solve NACLO problems from past years, answer your questions about the study of language, or talk to you about careers in computational linguistics.
