Abstract

The invention discloses a classifier construction and intelligent question answering method, device, terminal and readable storage medium. The method includes: acquiring at least one piece of training data, which is corpus data with at least one layer of classification features, and using the at least one piece of training data, constructing an initial tree classifier, and using the at least one piece of training data to train the initial tree classifier based on a preset machine learning algorithm to obtain a tree classifier. Compared with the prior art, by using training data with at least one layer of classification features to construct and train an initial tree classifier, the classification method of the trained tree classifier is more reasonable, and the tree classifier is used for intelligent question answering, It can effectively improve the accuracy of intelligent question answering.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a classifier construction and intelligent question answering method, device, terminal and readable storage medium. Background technique [0002] The emergence of the intelligent question answering system is to meet the needs of users for self-questioning and self-answering. It can quickly and intelligently answer voice or text questions raised by users. When a user asks a question to the intelligent question answering system, the intelligent question answering system will recognize the question. And determine the answer, and convert the answer into a text or multimedia file according to the scene and output it. [0003] The existing technologies that are widely used in the field of intelligent question answering and even in the field of professional question answering are mainly: keyword search combined with semantic understanding, entity recognition and o...
