specific example

[0182] Now give a specific example to illustrate the method of the present invention: Taking the microblog service as an example, the user submits a question to the self-service customer service: "I want to pay attention to others, is it okay? Thank you." The method of the present invention is described in detail below The process of outputting the answer content.

[0183] The questions are regular, remove irrelevant strings, such as "thank you", and automatically mark keywords in the field or words related to the product, such as "follow"; segment the questions to get: I \ think \ follow \ others \ no \ problem ;Extract the keyword "follow", and extract a binary string composed of adjacent single-character words (a single-character word is a word containing only one Chinese character after word segmentation) as a keyword supplement, such as "I" and "think" Compose "I think" as a supplement, binary strings need to meet certain conditions as vector elements, for example, when t...

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...
