Embodiment Construction

[0022] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a method for building a knowledge base according to the present invention, which may specifically include the following steps:

[0024] Step 101, obtaining the existing standard questions in the knowledge base to be constructed and the first extended questions associated with the standard questions;

[0025] Among them, the standard question is a standard description of the knowledge point. Compared with the standard question, the extended question associated with the standard question is a description that is semantically similar to the standard question and has richer and more semantic information. Both standard questions and extended questions...

Abstract

The present invention provides a method and device for constructing a knowledge base. The method includes: acquiring an existing standard question in the knowledge base to be constructed and a first extended question associated with the standard question; according to the standard question and the first extended question An extended question, mining a second extended question semantically matching the standard question and the first extended question from the corpus to be mined; transferring and storing the second extended question from the corpus to be mined to the to-be-mined Constructing a knowledge base, and associating the second extended question with the standard question semantically matched with the second extended question, wherein the second extended question stored in the knowledge base to be constructed is denoted as The first extension asks. When building the knowledge base, the invention does not need manual marking, realizes the automatic construction of the knowledge base, saves manpower and financial resources, improves the construction efficiency of the knowledge base, and shortens the construction period of the knowledge base.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a knowledge base construction method and device. Background technique [0002] Knowledge base, also known as intelligent database or artificial intelligence database, is a structured, easy-to-operate, easy-to-use, and comprehensively organized knowledge cluster built for the needs of solving problems in a certain (or some) domains in knowledge engineering. The knowledge base uses certain (or several) knowledge representation methods to store, organize, manage and use in the computer, and has mutual correlations. The knowledge base generally consists of knowledge points, standard questions and their corresponding extended questions. For example, in the intelligent customer service system, if a certain knowledge point is "check phone bills", and the standard question is "phone bill inquiry", then there are many corresponding extended questions, which can be "how mu...
