Intelligent question answering knowledge base establishment method, establishment device and establishment system

Abstract

The invention relates to an intelligent question answering knowledge base establishment method, establishment device and establishment system. The establishment method comprises the following steps: providing a domain knowledge data base, wherein the domain knowledge data base comprises a plurality of pieces of preset knowledge; receiving initial request information; performing semantic similarity calculation on the initial request information and the preset knowledge in the domain knowledge data base, and judging whether the maximum value of the semantic similarity calculation results is larger than a similarity threshold or not; if the maximum value of the semantic similarity calculation results is larger than the similarity threshold, storing a standard question and an extended question in the preset knowledge corresponding to the initial request information and the maximum value of the semantic similarity calculation results in the intelligent question answering knowledge base; if the maximum value of the semantic similarity calculation results is smaller than the similarity threshold, carrying out the abstract semantic recommendation process so as to acquire one or more specific semantic expressions corresponding to the initial request information, and storing the initial request information and the specific semantic expressions in the intelligent question answering knowledge base. The establishment method provided by the invention can improve the establishment efficiency of the intelligent question answering knowledge base.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device and system for establishing an intelligent question-and-answer knowledge base. Background technique [0002] Knowledge base, also known as intelligent database or artificial intelligence database. The knowledge base is a structured, easy-to-operate, easy-to-use, comprehensively organized knowledge cluster in knowledge engineering. It is aimed at the needs of solving problems in a certain (or some) fields, and uses a certain (or several) knowledge representation methods in the computer memory. A collection of interconnected pieces of knowledge stored, organized, managed, and used in . These pieces of knowledge include domain-related theoretical knowledge, factual data, and heuristic knowledge obtained from expert experience, such as definitions, theorems, algorithms, and common sense knowledge related to a certain domain. [0003] The knowledge base has ...

AI Technical Summary

Problems solved by technology

[0005] Due to the different angles and expressions of different users asking questions, in order to improve the accuracy of the intelligent question answering system, when presetting the questions in the question bank, it is necessary to manually input multiple questions with different expressions from the man-machine interface, which consumes a lot of time. Time-consuming, labor-intensive, and low efficiency, so the efficiency of existing storage devices for problem storage needs to be improved
