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 the Ohio State University will be a local site. The open round of the contest will take place on Thursday, January 30, 2014. Well-performing students will be invited to a second round to be held on March 13. 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.

 

Information Session

This year, we're trying something different with information sessions. If your school is sponsoring a NACLO team, let us know and we can arrange to come to you and hold an information session at your convenience! Please email us at naclo@ling.osu.edu for more information.

Where is the OSU site for the contest?

The competition is in the Senate Chamber, on floor 2 of the OSU Student Union, which is located at 1739 North High. Parking is located next door.

When should I arrive?

The contest starts at 10 a.m. sharp and goes until 1 p.m. on Thursday, January 29. Please arrive early, at about 9:30 a.m., as we will go over the rules prior to the start of the contest. After the contest, there will be refreshments and a discussion of opportunities for studying linguistics and computational linguistics at Ohio State.

What is the competition schedule?

  • 9 am: competition room opens
  • 9:30 am: all contestants should arrive by this time
  • 10 am: competition starts
  • 1 pm: competition ends
