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 system, which are used to solve the problem of huge workload and narrow coverage of establishing a Chinese question-and-answer sentence database when pattern matching technology is used to realize Chinese automatic answering in the prior art. The method includes the steps of: determining the category and keyword sequence of the Chinese sentence input by the user, searching the keyword sequence identical to the category of the user input sentence from the question-and-answer sentence database, combining the keyword sequence of the user input sentence with the searched keyword sequence The keyword sequence is matched, and the response statement corresponding to the successfully matched keyword sequence is returned to the user; the system includes a user statement analysis module and a query module. The invention improves the content coverage of the question-and-answer sentence database, reduces the workload of building the database, and simultaneously significantly improves the accuracy rate and recall rate of the Chinese automatic answering system.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a Chinese automatic answering method and system. Background technique [0002] Natural language understanding technology is an important research direction in the field of artificial intelligence. It enables computers to understand and use human natural language, and can realize effective communication between humans and computers based on natural language. The natural language here includes various natural languages ​​used by humans, such as Chinese, English and so on. The QA (automatic Question Answering) system is a system with natural language understanding technology as the core, which completes the analysis and processing of user questions on the one hand, and completes the generation of correct answers on the other hand. [0003] The performance of the automatic response system is mainly characterized by the two indicators of accuracy and recall, which are explained b...
