After introducing the basic framework of LFG in Chapter 2, I describe the core syntactic and morphological aspects of Japanese in Chapter 3: non-configurationality; the concept of \"bunsetsu\" r syntactic units and their dependency relationship represented in Directed Acyclic Graphs (DAGs); topicalisation by a particular particle; and frequent use of zero pronouns with or without over antecedents. Inflecting parts-of-speech and non-inflecting parts-of-speech of Japanese are also described with examples. In Chapter 4, I provide the linguistic representation of core grammatical features and functions of Japanese in the framework of LFG.I use Directed Acyclic Graphs (DAG) as a framework for the unified representation f surface syntactic, morphological and lexical information in an LFG f-structure. In Chapters 5 and 6, I describe the automatic annotation algorithm of LFG f-structure functional equations (i.e. labelled dependencies) to the Kyoto Text Corpus version 4.0 (KTC4) and the output of Kurohashi-Nagao Parser (KNP provide unlabelled dependencies only. The method presented in this dissertation also includes zero pronoun identification. Finally in Chapter 7 I evaluate the performance of the f-structure annotation algorithm with zero-pronoun identification for KTC4 against a manually-corrected Gold Standard of 500 sentences randomly chosen from KTC4.
