Morphophonology in Unification-Based Grammar

X2MORF: A Morphological Component Based on Augmented Two-Level Morphology

X2MORF 1 is a language independent morphological component for the recognition and generation of word forms based on a lexicon of morphs. The approach is based on two-level morphology. Extensions are motivated by linguistic data which call into question an underlying assumption of standard two-level morphology, namely the independence of morphophonology and morphology as exemplified by two-leve...

Parsing Korean based on Dependency Grammar and GULP

This paper presents a parsing algorithm in Prolog using GULP, based on dependency grammar and unification-based grammar.1 It parses declarative sentences of a free-word-order language, Korean. The dependency grammar accepts free order of the words in a sentence. Unification-based features separate the grammar from the parsing algorithm and also simplify the notation of the grammar. GULP (Graph ...

Synchronous Tree Unification Grammar

This paper presents a novel grammar formalism, Synchronous Tree Unification Grammar (STUG), that borrows ideas from two rather distinct exemplars of tree-based grammar formalisms, namely Synchronous Tree Adjoining Grammar and Tree Unification Grammar. At the same time STUG differs considerably from those in that it allows for a clean separation of syntax and valency. Exploiting this potential i...

THE SIXTH JAPANESE-KOREAN JOINT CONFERENCE ON FORMAL LINGUISTICS ,1991 Unification in Unification-based Grammar

In the computational linguistics area, after Kay's adopting of feature structures and their unification to manipulate syntactic structures[KAY79], a lot of unification-based grammar formalisms have been issued such as FUG[KAY82] , LFG[BRE82] , GPSG[GAZ85] , PATRII[SHI86], HPSG[P0L87], etc.. Nowadays, an unification of feature structures is known as one of the most effective and powerful means t...
