Zusammenfassung:The invention discloses a tax questioning and answering system, and discloses a device, a terminal and a storage medium with the tax questioning and answering system, the tax questioning and answering system uses a BERT model pre-trained by a general text to carry out word vector representation on a text, and is applied to research and development of the tax questioning and answering system, construction of a tax system data set and implementation of the tax questioning and answering system. According to the method, the similarity of the questions and answers is calculated, meanwhile, a cross entropy optimization model is used, and in the question retrieval process, the questions are divided into a primary screening process and a secondary screening process, so that the model can have better performance in the tax field, and meanwhile, the reaction efficiency is improved. 本发明公开了一种税务问答系统,并公开了具有税务问答系统的装置、终端及存储介质,其中税务问答系统使用通用文本预训练的BERT模型对文本进行词向量表示,应用于税务问答系统研发,构建税务系统数据集,并将问题与答案的相似度分别进行计算,同时使用交叉熵优化模型,并且在问题检索过程中,将问
