Man-machine interaction method and system based on artificial intelligence

A man-machine interaction method and system based on artificial intelligence. The man-machine interaction method based on artificial intelligence comprises the following steps: receiving input information input by a user through an application terminal (S1); acquiring intent information about the user according to the input information about the user, and distributing the input information to at least one interaction service subsystem according to the intent information (S2); receiving a return result returned by the at least one interaction service subsystem (S3); and generating a user return result according to the return result in a pre-set decision strategy, and providing the user return result to the user (S4). In the method and system, the man-machine interaction system is anthropomorphic instead of being instrumentalized, and the user can obtain relaxed and pleased interaction experience in the intelligent interaction process through chat, research and other service. The search in the form of keywords is improved into natural language based search, the user can express demands through flexible and free natural languages, and a multi-round interaction process is closer to the interaction experience among humans.
