Natural Language Understanding And Standardization Of Maintenance Information

Chinese semantic analysis is the most important and difficult problem of Chinese Natural Language Understanding. The description and integration of Information Standardization is namely semantic analysis to informational description. The thesis restricts the research in one given field-Aircraft Maintenance Information. In this sublanguage the problem can be simplified, so we can get simpler and clearer semantic system and it make up the base of natural language understanding in aircraft maintenance information. Our research involves the foundation of machine dictionary, the design of rule stack, the application and revision of current semantic clarifying system, the store form of language knowledge in database and the relation in all kinds of semantic matching. We do most work in some algorithms, especially modifier and bring forward some algorithms. And at last we build a natural language understanding system-The Aircraft Maintenance Information Standardization System.
