| Research Abstract |
This research project investigated a Japanese practical lexicalized grammar and proposed an algorithm of building a large-scale grammar by(semi-) automatic extraction of lexical entries from corpora. When sentences become longer because of some linguistic complexity the parsing performance deteriorates. Under the framework of CCG, HPSG and DRT, we analyzed such linguistic matters as complex predicates, complex sentences and relative clauses in Japanese, and showed a human sentence processing strategy based on a linguistic formalization, which is also available for inducing a CCG grammar from an annotated corpus.
