Type Inheritance and Constraints of Phonological Information on HPSG

by Michinao Matsui

Type inheritance is one of the most effective methods to compact information of lexical items. Some generative grammars including Head-driven Phrase Structure Grammar (HPSG) adopt this approach. Many researches have cleared the aspects of semantic or syntactic type subsumpition. However, little is known about computational features of constraints based on phonological types. This study draws the outline of type inheritance of phonological information in lexical items.
