Automatic question answering method, automatic question answering system and method for constructing question answering case base

Abstract

The invention discloses an automatic question answering method, an automatic question answering system and a method for constructing a question answering case base. The automatic question answering method mainly includes vectorizing questions submitted by users by using the question answering case base which stores question answering cases in a vector mode to generate question vectors, searching answer knowledge point IDs with satisfactory similarities by using the question vectors and the question answering case base containing case vectors, and obtaining answer content output to users from a knowledge point document case by using the answer knowledge point IDs. According to the system and the methods, the cost can be reduced, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the field of computer natural language processing, in particular to an automatic question answering method, an automatic question answering system and a method for constructing a question answering example database. Background technique [0002] At present, many industries need to undertake more and more work of answering user inquiries and feedback, such as after-sales service or customer service in the Internet industry. Due to the exponential growth of the number of users, it is no longer possible to use manual methods to provide feedback or timely answers to all user inquiries, and most of the user's questions are concentrated on certain specific knowledge points, and manual responses are often repetitive labor, so , there is an urgent need for a simple, efficient, and easy-to-maintain system to assist humans in answering questions. [0003] Automatic Question Answering (Question Answering, QA) refers to finding a clear an...

AI Technical Summary

Problems solved by technology

[0006] The knowledge base construction and maintenance cost of the existing automatic question answering system is relatively high, and business personnel need to summarize common question templates for a certain knowledge point, and operation and maintenance need to continuously add new templates; since the template library will become larger and larger, reasoning The process of unit reasoning and calculation will become more and more time-consuming, resulting in complex calculations, uncontrollable response time, and low work efficiency. The existing automatic question answering system needs to be further improved
