LING 388: Language and Computers Sandiway Fong Lecture 23

Last Time We started building a Prolog Japanese grammar …

Japanese Grammar Example: – taroo-ga hon-o kaimashita – (john)-nom book-acc buy+past (formal/polite)

Japanese Grammar Example: – taroo-ga hon-o kaimashita – (john)-nom book-acc buy+past (formal/polite) kaimashita

Japanese Grammar Example (scrambled): – hon-o taroo-ga t kaimashita – book-acc (john)-nom trace buy+past (formal/polite)

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

Japanese Grammar Example (wh-question): – dare-ga hon-o kaimashita ka – who-nom book-acc buy+past Q – Define 2 nd argument for NPs with value notwh/wh Q = question particle who what WHNP/WP tags following the Stanford parser:

Japanese Grammar Example (wh-question): – dare-ga hon-o kaimashita ka – who-nom book-acc buy+past Q – Define 2 nd 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

Japanese Grammar Example (wh-question): – dare-ga hon-o kaimashita ka – who-nom book-acc buy+past Q – Define 2 nd 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

Japanese Grammar Example (wh-question): – dare-ga hon-o kaimashita ka – who-nom book-acc buy+past Q – Define 2 nd 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

Japanese Grammar Example (wh-question): – dare-ga hon-o kaimashita ka – who-nom book-acc buy+past Q – hon-o dare-ga t kaimashita ka – book-acc who-nom trace buy+past Q Scrambled wh-question

Japanese Grammar Example (wh-question): – taroo-ga nani-o kaimashita ka – (John)-nom what-acc buy+past Q is not represented in the parse

Japanese Grammar Lets modify j23.pl 1.to use SQ instead S for wh-questions 2.Verb morphology: kau + masu + ta = kaimashita (masu = polite, ta = past) kau + ta = katta(informal) 3.Yes/No questions: Sentence-final ka without wh-word as subject or object taroo-ga hon-o kaimashita ka Did Taroo buy a/the book?

Japanese passives Patterns: – Object-ga V-passive – Object-ga Subject-ni V-passive From wikipedia
