| Outline of Final Research Achievements |
Parsing for Japanese is known to be useful for machine translation or knowledge acquisition, but there are several problems in analyzing grammatical semantic roles because Japanese often involves omission and has ambiguous case markers. This study proposes a method for developing a Japanese Head-Driven Phrase Structure grammars (HPSG) and its treebank, and also proposes a deterministic parsing method for Japanese HPSG grammars by using neural network classifiers. We firstly obtain a Japanese HPSG treebank by using annotated corpora with syntactic analysis and case analysis, and then we obtain a Japanese HPSG grammar which provides both syntactic and case analyses by using the developed treebank.
