The 2020 North American Computational Linguistics Open at LIU Post


We are excited to announce that LIU Post will be a site host for the 2020 North American Computational Linguistics Open (NACLO). NACLO is a contest in which high-school students solve linguistic puzzles. In solving these puzzles, students learn about the diversity and consistency of language, while exercising logic and problem-solving skills. No prior knowledge of linguistics or computing is necessary and participation is free. Professionals in linguistics, computational linguistics and language technologies use dozens of languages to create engaging problems that represent cutting edge issues in their fields. The competition has attracted top students to study and work in those same fields. It is truly an opportunity for young people to experience a taste of natural-language processing in the 21st century.

What kinds of students are interested in NACLO? Typical NACLO participants enjoy puzzles and languages and take math, language, and/or computer classes.

What’s in it for you? Students participating in this open will learn about a new field of study, participate in fun games, partake in an enriching experience and add an item to their resumes that will help in the college admissions process.

When is it? The Open Round of testing will be on Thursday, January 23, 2019 at 10:00am at Long Island University, Post Campus in Humanities 220 (second floor). Please arrive 15 minutes early so that we can start promptly at 10. The test lasts for 3 hours and consists of 3-8 problems. Last year there were more than 1,000 participants at 100 test sites, and participation continues to grow. Winners of the Open Round are invited to the Invitational Round, and the winners of the Invitational Round are eligible to participate in the International Linguistics Olympiad.

How can I prepare? For students interested in participating, Stony Brook University will host a voluntary training session that will include practice problems, test-taking tips, as well as an overview of linguistics and computational linguistics. The training session will be held on Sunday January 18, 2020 in SBU’S IACS Seminar Room, from 1–3:00pm.
