| Outline of Final Research Achievements |
This research project designed a Japanese lexicalized grammar based on Combinatory Categorial Grammar (CCG) and considered an algorithm of (semi-)automatically extracting logical forms from corpora by using CCG derivations. When sentences get longer because of some linguistic complexity the parsing performance deteriorates. Under the framework of CCG, we analyzed such linguistic matters as multiple-GA, GA-NO conversion and locative NI-DE alternation in Japanese, and proposed a syntactic and semantic parsing strategy, which is also available for inducing a CCG grammar from an annotated corpus.
