A semantic analysis system based on HPSG with the mental‐image directed semantic theory built in

Abstract

SUMMARYThe authors have developed a syntactic and semantic HPSG analysis system based on Mental-Image Directed Semantic Theory (MIDST). While conventional HPSG and JPSG parsers are based on situation semantics, MIDST provides a representation with deeper meaning for natural language by referring to the mental images evoked. Semantic analysis systems based on MIDST, however, have to date employed dependency grammar, requiring word meaning to be represented in two parts. HPSG describes such meanings uniformly, allowing for analysis systems with wide coverage. The proposed system has been developed using common analysis engine for both English and Japanese, requiring only the change of resources such as lexical entries and grammar rules.
