A method and device for intelligent question answering based on knowledge graph

Abstract

The embodiment of the present invention relates to a method and device for intelligent question answering based on a knowledge map, the method comprising: collecting multiple pieces of information text to generate a first knowledge base; creating a corresponding first knowledge map; obtaining first question information input by a user; Perform theme extraction to generate first theme data; use the first knowledge node matching the first theme data as the first main knowledge point; classify and arrange other first knowledge nodes associated with the first main knowledge point to obtain multiple first Class associated knowledge node sequence; query the first knowledge base according to the first main knowledge point to obtain the content data of the first main knowledge point; query the first knowledge base according to each first type associated knowledge node sequence to obtain the first type associated knowledge point content data set ; Feedback to the user by composing the first question response information in the order that the content data of the first main knowledge point comes first, and the content data of each first type of related knowledge point is collected later. The method of the invention solves the problem of single conventional automatic answering content.

Description

technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to an intelligent question answering method and device based on knowledge graphs. Background technique [0002] Information display platforms or social platforms have begun to add service windows with automatic response functions on the platforms in order to provide timely feedback on user problems and improve user experience. However, we have found in practical applications that the feedback content of these current automatic answering services is based on the preset question-answer correspondence when processing user responses, and pushes a single content. Additional questions are required. In this case, the more relevant information the user wants to know, the more input operations will be required, which will undoubtedly cause a problem of declining user experience. Contents of the invention [0003] The purpose of the present invention is to address the def...
