Abstract

The invention provides a question-answering method based on a Bayesian network. The method includes: receiving and parsing a question sentence, which is input by a user through a client, to identify atarget parameter, which represents user intent, and attribute parameters, which are associated with the target parameter, in the question sentence; inputting the target parameter and the attribute parameters into a pre-trained Bayesian network model, and utilizing a directed acyclic graph (DAG) and a conditional probability table set of the Bayesian network model to infer and obtain a value of the target parameter; and feeding back the value, which is of the target parameter and inferred and obtained by the Bayesian network model, to the user. According to the method, causal reasoning is carried out on the question sentence, and a question provided by the user is answered on the basis of a reasoning result. The invention also provides a question-answering device based on the Bayesian network and a computer-readable storage medium.

Description

technical field [0001] The present invention relates to the technical field of human-computer interaction, in particular to a Bayesian network-based question answering device, method and computer-readable storage medium. Background technique [0002] Human-computer interaction is a science that studies the interactive relationship between systems and users. Among them, a system can be a variety of machines, or it can be a computerized system and software. Various artificial intelligence systems can be realized through human-computer interaction, such as intelligent customer service systems, voice control systems, and so on. The intelligent question answering system is a typical application of human-computer interaction. When a customer asks a question, the intelligent question answering system automatically replies to the user with the answer to the question. However, most of the existing intelligent question answering systems are obtained by searching text or knowledge ba...
