Unlocking Linguistic Puzzles

OzCLO offers Secondary students an opportunity to delve into language structure through puzzles, with top performers advancing to international competition. Despite not advancing, our Heathdale teams earned distinctions and are motivated to excel next year!

The Australian Computational and Linguistics Olympiad (OzCLO) is a well-established contest for Secondary students that aims to help them learn about the systematic nature of language through puzzles based on several types of language data. It challenges students to develop strategies for solving language problems related to both real and extinct languages, as well as codes.

The OzCLO contest is held in two rounds, with the first round being a two-hour competition held in early March. The second round is held offline for the top-scoring teams, with the final winners earning the opportunity to travel abroad and compete in the International Linguistics Olympiad. This year, the international round will take place in Brasilia, Brazil, in late July.

Three teams from our school competed in this year’s first round of the OzCLO competition. Unfortunately, we did not advance to the next level, but we performed admirably, earning silver and bronze distinctions. This has motivated our teams to strive for further success next year.

The OzCLO contest is open to all Secondary students who have a keen interest in languages and enjoy working in teams to solve linguistic problems. Interested students are encouraged to register early next year and participate in training sessions prior to the contest.

“Participating in OzCLO was an incredibly enriching experience. I learnt a great deal about the structures of language and the computational approaches used to analyse them. It was fascinating to discover how linguists decipher patterns in unfamiliar languages. Working within our group was a positive experience. We collaborated well, dividing tasks efficiently to tackle the complex problems we faced. I especially appreciated the chance to brainstorm and strategise with my teammates. Overall, I'm so grateful for the opportunity to participate in OzCLO. I feel that I've gained valuable insights into the fascinating field of linguistics and am excited to apply these new skills going forward.” Shriyans S.
