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 ...
