Abstract

A Bayesian network-based question-answering method, a question-answering apparatus and a computer-readable storage medium. The method comprises: receiving and parsing a question input by a user by means of a client, so as to recognize in the question a target parameter representing user intent and an attribute parameter associated with the target parameter (S10); inputting the target parameter and the attribute parameter into a pre-trained Bayesian network model, and using a directed acyclic graph and a conditional probability table set of the Bayesian network model to infer a value of the target parameter (S20); returning the value of the target parameter inferred by the Bayesian network model to the user (S30). The present method performs causal inference of a question, and on the basis of an inferred result, answers a question put forth by a user.

Description

Technical field [0001] The present invention relates to the technical field of human-computer interaction, and in particular to a question and answer device, method and computer readable storage medium based on Bayesian network. Background technique [0002] Human-computer interaction is the science of studying the interactive relationship between the system and the user. Among them, the system can be a variety of machines, or computerized systems 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 the customer asks a question, the intelligent question answering system automatically responds to the user the answer to the question. However, in the existing intelligent question answering systems, the answers are mostly obtained by searching text o...
