Abstract

The invention relates to the technical field of artificial intelligence, in particular to an intelligent question answering method and device based on a bidirectional attention mechanism, equipment and a medium. The method comprises the steps: adopting a first bidirectional LSTM coding layer for coding a text and a problem to obtain a text semantic feature vector and a problem semantic feature vector respectively, and then enabling the text semantic feature vector and the problem semantic feature vector to fully interact with each other to obtain a comprehensive interaction matrix of the text and the problem; inputting the comprehensive interaction matrix into the bidirectional LSTM model to output the answer, so the context information of the text and the question and the interaction characteristics of the text and the question are fully mined, the semantic representation of the text and the question is enriched, and the accuracy of intelligent question answering is improved. Moreover, intelligent question answering is carried out by using a bidirectional LSTM model in a reading understanding manner, and answers to the questions are automatically obtained from each text without depending on fixed corpora in a corpus.

Description

【Technical field】 [0001] The present invention relates to the technical field of artificial intelligence, in particular to an intelligent question answering method, device, equipment and medium based on a two-way attention mechanism. 【Background technique】 [0002] In the intelligent question answering scenario of the prior art, it is generally based on a corpus, and the corpus used is often limited. If the corpus cannot be updated in time, the accuracy rate will drop significantly, affecting customer experience, and the intelligent question answering based on the corpus lacks generalization ability, which is not conducive to improving the accuracy of intelligent question answering. 【Content of invention】 [0003] The object of the present invention is to provide an intelligent question answering method, device, equipment and medium based on a two-way attention mechanism, so as to solve the technical problem of low accuracy of intelligent question answering in the prior ar...
