  2. What is Computational Linguistics? • Linguistics is the study of language itself – how languages are formed, how we learn and understand languages, how languages work, etc. • Syntax • Semantics • Phonology • Morphology • Pragmatics • Computational linguistics is the science of designing algorithms and programming computers to “understand” the rules of languages that we intuitively know.

  3. Language Subtleties • Adjective order and placement • A big black dog • A big black scary dog • A big scary dog • A scary big dog • *A black big dog • Antonyms: which sizes go together? • Big and little • Big and small • Large and small • *Large and little

  4. Headline Ambiguity • DRUNK GETS NINE YEARS IN VIOLIN CASE • FARMER BILL DIES IN HOUSE • PROSTITUTES APPEAL TO POPE • STOLEN PAINTING FOUND BY TREE • INCLUDE CHILDREN WHEN BAKING COOKIES • MINERS REFUSE TO WORK AFTER DEATH

  5. Computational Linguistics in the World: • Internet Search Engines/Social Networks • Machine Translation • Speech Recognition • Artificial Intelligence • Cryptography • Education Technology

  6. So…what is this Olympiad? • The Olympiad will test your logical and analytical thinking skills to solve problems similar to the one you just saw • You will be given a set of problems to solve individually within a three-hour period • Success at the two state-level competitions will give you the opportunity to participate in the International Linguistics Olympiad in Poland

  7. A Sample Problem… Doing Math in Indonesian Definition: satu = 'one' • Satu ditambah satu menjadi dua. • Dua ditambah dua menjadi empat. • Satu ditambah dua menjadi tiga. • Dua dikalikan dua menjadi empat. • Enam dikurangi tiga menjadi tiga. • Sepuluh dikurangi enam menjadi empat. • Sepuluh dibagi dua menjadi lima. • Tiga dikalikan enam menjadi delapan belas. • Delapan belas dikurangi satu menjadi tujuh belas. • Tiga ditambah empat menjadi ___________. • Tiga dikalikan tiga menjadi sembilan.

  8. How did you solve that? • (Now imagine trying to get a computer to do the same thing!)

  9. Dates • February 4, 2009: • Qualifying Round @ UNT, Research Park, • Registration starts at 8:00am, competition starts at 8:45am • [Optional] January 29, 2009, 6pm, Research Park F223 • Practice session • March 11, 2009: • Invitational Round @ UNT, Research Park • Summer 2009: • International Linguistics Olympiad Training Camp • Summer 2009: • International Linguistics Olympiad in Poland

  10. Why Should You Participate? • Get introduced to an ever-growing field • Try a new challenge, with nothing to lose • Looks great on college resumes • A chance to travel world-wide • No prior experience necessary – just a head for analytical thinking and a can-do attitude
