Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a question-and-answer question generation method and device based on a knowledge base, using massive structured entity, attribute and attribute value information as the backbone data of the question, and the entity, attribute and attribute value One of the three elements is used as the correct answer, and the remaining two elements are used as the question components of the question. Compared with the existing human-edited question and answer library, it significantly improves the data conversion efficiency of massive knowledge data to question and answer questions and improves the question and answer questions. The richness of purpose; moreover, the automatic generation of question and answer question banks through massive structured data can avoid the memory bias of manual editing questions and improve the accuracy of answers

Embodiment Construction

[0020] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] see figure 1 , which illustrates a schematic flowchart of a method for generating questions and answers based on a knowledge base according to an embodiment of the present invention, the method may include:

[0022] S101. Obtain a triple data set from a knowledge base, where the triple data set includes three elements: an entity, an attribute, and an attribute value. The relationship between each element is: the attribute value element is the value corresponding to the attribute element of the entity element;

[0023] S102. Using any element in the triple data set as the correct answer, generate a question corresponding to the correct answer according to the template of language expression habits.

[0024] The question-and-answer q...

Abstract

The invention provides a knowledge database based question and answer generating method and apparatus. The method comprises: obtaining triple data set from the knowledge database, wherein the triple data set comprises such three elements as an entity, an attribute and attribute values; a relationship between the elements is: an attribute value element is a corresponding value of an attribute element of an entity element; and using any one of the elements in the triple data set as a correct answer, and generating a corresponding question of the correct answer according to a template of language idomatic expression. The above method and apparatus of the invention can use one element of the triple data set as the correct answer, and the other two elements are transformed into the trunk of the corresponding question; data conversion efficiency from mass structured knowledge data to question and answer is significantly improved according to language idiomatic expression.

Description

technical field [0001] The present invention relates to the Internet field, in particular to a method and device for generating questions and answers based on a knowledge base. Background technique [0002] Questions and answers to the questions are an effective way for people to acquire knowledge data or information in the real world. However, the knowledge data or information involved in the real world (especially on the Internet) is massive, and how to convert the massive knowledge data or information into questions and corresponding answers has become a technical problem that needs to be solved urgently. The conversion of existing knowledge data or information to questions and corresponding answers is mainly done manually, and the conversion data processing efficiency is low. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a question-and-answer question generation method and device based on a ...
