Unstructured text-oriented intelligent question and answer method and system

The invention belongs to the technical field of computer intelligent conversation and provides an unstructured text-oriented intelligent question and answer method and system. The method comprises thesteps that S1, a coding layer performs coding on obtained text and question to obtain a text hidden vector and a question hidden vector; S2, an information fusion layer fuses the text hidden vector and the question hidden vector, and obtains a fused correlation vector group; and S3, a decoding layer performs decoding on the text according to the correlation vector group to obtain an answer of thequestion and outputs the answer. The answer is directly given for the raised question of the unstructured text, without establishing a question and answer library in advance; the type of the raised question is not limited; the returned answer is relatively accurate; and the data-driven design is adopted, so that big data is effectively utilized. 本发明属于计算机智能对话技术领域，提供了种面向无结构文本智能问答的方法和系统，包括：S1，编码层将获取到的文本和问题分别进行编码，得到文本隐藏向量和问题隐
