Similarity calculation-based questions and answers knowledge base establishing method, device and system

Abstract

The present invention relates to a similarity calculation-based questions and answers knowledge base establishing method, device and system, wherein the establishing method comprises the steps of providing a field knowledge database, wherein the field knowledge database comprises a plurality of preset knowledge, and the preset knowledge comprises a standard question and a or a plurality of expansion questions; receiving the initial request information; carrying out the semantic similarity calculation on the initial request information and the preset knowledge in the field knowledge database, and determining whether the maximum value of a semantic similarity calculation result is greater than a similarity threshold value, when the semantic similarity calculation result is greater than the similarity threshold value, storing the standard questions and the expansion questions in the preset knowledge corresponding to the initial request information and the maximum value of the similarity calculation result in an intelligent questions and answers knowledge base. The establishing method, device and system of the present invention enables the establishment efficiency of the intelligent questions and answers knowledge base to be improved.

Description

technical field [0001] The invention relates to data processing technology, in particular to a method, device and system for establishing a question-and-answer knowledge base based on similarity calculation. 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 ba...

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
