  1. LING 388: Language and Computers Sandiway Fong Lecture 23

  2. Last Time • We started building a Prolog Japanese grammar …

  3. Japanese Grammar • Example: • taroo-gahon-o kaimashita • (john)-nom book-accbuy+past (formal/polite)

  4. Japanese Grammar • Example: • taroo-gahon-o kaimashita • (john)-nom book-accbuy+past (formal/polite) kaimashita

  5. Japanese Grammar • Example (scrambled): • hon-o taroo-gat kaimashita • book-acc (john)-nom trace buy+past (formal/polite)

  6. Japanese Grammar • Example (scrambled): • hon-o taroo-gat kaimashita • book-acc (john)-nom trace buy+past (formal/polite) or..

  7. Japanese Grammar • Example (wh-question): • dare-gahon-o kaimashitaka • who-nom book-accbuy+past Q • Define 2nd argument for NPs with value notwh/wh Q = question particle who what WHNP/WP tags following the Stanford parser:

  8. Japanese Grammar • Example (wh-question): • dare-gahon-o kaimashitaka • who-nom book-accbuy+past Q • Define 2nd argument for NPs with value notwh/wh • Add a new nonterminal sf(sentence final) that generates ka when either the subject or object has value wh

  9. Japanese Grammar • Example (wh-question): • dare-gahon-o kaimashitaka • who-nom book-accbuy+past Q • Define 2nd argument for NPs with value notwh/wh • Add a new nonterminal sf(sentence final) that generates ka when either the subject or object has value wh We assume that the question particle ka is obligatory

  10. Japanese Grammar • Example (wh-question): • dare-gahon-o kaimashitaka • who-nom book-accbuy+past Q • Define 2nd argument for NPs with value notwh/wh • Add a new nonterminal sf(sentence final) that generates ka when either the subject or object has value wh

  11. Japanese Grammar • Example (wh-question): • dare-gahon-o kaimashitaka • who-nom book-accbuy+past Q • hon-o dare-gatkaimashitaka • book-acc who-nom trace buy+past Q Scrambled wh-question

  12. Japanese Grammar • Example (wh-question): • taroo-ganani-o kaimashitaka • (John)-nom what-accbuy+past Q is not represented in the parse

  13. Japanese Grammar • Let’s modify j23.pl • to use SQ instead S for wh-questions • Verb morphology: • kau + masu + ta = kaimashita • (masu = polite, ta = past) • kau + ta = katta (informal) • Yes/No questions: • Sentence-final ka without wh-word as subject or object • taroo-gahon-o kaimashitaka • Did Taroo buy a/the book?

  14. Japanese Grammar • Let’s modify j23.pl • to use SQ instead S for wh-questions

  18. Japanese Grammar • Let’s modify j23.pl • Yes/No questions: • Sentence-final ka without wh-word as subject or object • taroo-gahon-o kaimashitaka • Did Taroo buy a/the book?

  19. Japanese Grammar • Let’s modify j23.pl • Yes/No questions: • Sentence-final ka without wh-word as subject or object • taroo-gahon-o kaimashitaka • Did Taroo buy a/the book?

  20. Japanese Grammar • Let’s modify j23.pl • Yes/No questions: • Sentence-final ka without wh-word as subject or object • taroo-gahon-o kaimashitaka • Did Taroo buy a/the book?

  21. Japanese passives • Patterns: • Object-ga V-passive • Object-ga Subject-ni V-passive From wikipedia
