Embodiment Construction

[0062] The main design concept of the technical solution of the present invention is to propose a method that can reduce the amount of work required to establish a Chinese question-and-answer statement library when the existing Chinese automatic answering system uses pattern matching technology to realize Chinese automatic answering and has a narrow coverage. The workload of the Chinese question-and-answer statement database and the solution to significantly improve the content coverage of the question-and-answer statement database. The solution first determines the category and keyword sequence of the Chinese sentence entered by the user, and then searches the question-and-answer statement database that matches the category of the user-input statement. For the keyword sequence of the same question sentence, match the keyword sequence of the user input sentence with the found keyword sequence, and return the answer sentence corresponding to the successfully matched keyword seque...

Abstract

The invention discloses a Chinese automatic answering method and a system. The invention solves the problems of huge work quantity and narrow cover range for establishing a Chinese question and answer statement base in the prior art when the Chinese automatic answering is achieved by a mode matching technique. The method comprises the steps that: the style and the key word sequence of the Chinese statement input by customer are determined; a key word sequence that is the same as the style of the statement input by the customer is searched from the question and answer statement base; the key word sequence of the statement input by the customer is matched with the searched key word sequence; and the answering statement corresponding to the key word sequence which is matched successfully is returned to the customer. The system comprises a customer statement analyzing module and an inquiring module. The invention has the advantages of increasing the content cover range of the question and answer statement base, reducing the work load for establishing the base, and obviously enhancing the accuracy and the recall rate of the Chinese automatic answering system.
