Design And Implementation Of English Grammar Automatically Check The Wrong System

Natural language processing is a thriving interdiscipline concerned with computer science, linguistics, mathematics, etc. Ill-formed language processing is the essential research when the natural language processing technology is applied into the real world. And, grammar check is one of the ill-formed language processing research projects that have promising market profit.Parsing and checking are two necessary processes in grammar check. However, the current approach of parsing first and checking then limits the ability of current grammar check systems.Many application systems include their subsystems in grammar check, which function well because the error nature is obvious in the application. Yet, the subsystem methods are dependent on that of their host-system, so that there is lack of generality.In this paper, a multi-level approach to error check is presented, which is based on the rule-based deterministic parsing. It is characterized by dividing parsing process into multiple levels of differential depth, from least to most, and interleaving parsing with error check at each level. So, on the whole, checking and parsing are combined closely. In addition, the rule-based method makes the system flexible, not limited to the processing of English.The design principle and the procedure of the approach are demonstrated. Next is the knowledge presentation system. The system implementation includes the overall structures and algorithm explanations. Followed are the instance analysis, which illustrates the procedure of dealing with the sentence, and performance analysis, which presents the system's ability to cope with the disagreement between subject and predicate in sentences. Finally, the further development of the system is discussed in the view of practical application.
