The invention relates to an intelligent WeChat bank system based on a natural language automatic scheduler. The intelligent WeChat bank system based on the natural language automatic scheduler comprises a natural language input device, a natural language processing device, a predicate extracting and processing device, a function ontology annotating device, a question and function matching device, a constraint extracting and processing device, a parameter matching device, a function calling device and a result displaying device, wherein the natural language input device is used for receiving and describing call commands or questions, the natural language processing device is used for processing specific vocabularies, the predicate extracting and processing device is used for extracting and processing first-order predicates, the function ontology annotating device is used for carrying out ontology annotation on functions and parameters in a function library, the question and function matching device is used for matching the input commands or questions with the corresponding functions, the constraint extracting and processing device is used for extracting constraint data, the parameter matching device is used for enabling numerical values in constraints to correspond to numerical values of function parameters, the function calling device is used for completing assembly function calling, and the result displaying device is used for displaying a processing result. According to the intelligent WeChat bank system based on the natural language automatic scheduler, natural language demands of users can be intelligently recognized and automatically mapped to corresponding programs, the commands are executed, finally, results are fed back to clients, and the control over a computer system through the natural language is achieved.
