NACLO 2013

« previous post | next post »

The first round of the 2013 North American Computational Linguistics Olympiad will take place on January 31, 2013, at 45 sites around the U.S. and Canada. As the NACLO web site explains, this

… is a contest in which high-school students solve linguistic puzzles. In solving the problems, students learn about the diversity and consistency of language, while exercising logic skills. No prior knowledge of linguistics or second languages is necessary. 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.

Problems and solutions from the 2012 competition are available here.

Dragomir Radev contributed a LLOG post about the first NACLO, back in 2007; and NACLO veterans have done well in recent International Linguistics Olympiads. Registration at most sites is open through January 30, 2013.

    I'm enjoying attempting the 2012 competition packet. Sadly, the solution packet gives the answers, but no explanations. I spent 20 minutes on the second section (Learn Yolmo with pleasure), and got the first and second questions wrong (I got the third one right, and still don't understand it!)

    Can anybody explain the answers to this one? This sort of thing is fascinating! I need to know what nyimu means!

    Can't really help more without more information, but make sure to understand the difference between inherent possession (my nose, my arm, etc.) and alien possession (my money, my pants, etc.).
