摘　　要：中国海关传统的人工商品税率审查方式存在效率低、判断依据不一致、精度不高等问题,使用文本分类方法对商品分类自动确定税率可以有效降低海关税率风险。但面向海关商品数据进行分类时,商品类别具有层次性,同一大类下的许多子类别的商品描述具有高度相似性,给商品分类带来了很大的挑战。因此,提出了一种归纳交互网络模型,在BERT和CNN基础上加入归纳和交互指导模块。在归纳模块中采用动态路由算法对CNN提取的特征进行迭代运算,可以有效解决相邻特征融合和冗余问题。同时,为了解决不同子类别之间特征相似问题,提高分类性能,引入交互指导模块,该模块主要是将归纳模块提取的特征信息同[CLS]分类向量进行交互。在真实的海关数据集上进行实验,实验结果表明,该方法能达到较好的效果,其中准确率高达92.98%,且性能明显优于各基线模型。The traditional way of examining the tax rate of manual goods in China Customs has problems such as low efficiency,inconsistent judgment basis and low precision.Using text classification method to automatically determine the tax rate of commodity classification can effectively reduce the risk of customs tax rate.However,when classifying customs commodity data,commodity categories are hierarchical.Many sub-categories under the same category have highly similar commodity descriptions,which brings great challenges to commodity classification.Therefore,an inductive interactive network model is proposed,and inductive and interactive guidance modules are added on the basis of BERT and CNN.In the induction module,the dynamic routing algorithm is used to perform iterative operation on the features extracted by CNN,which can effectively solve the problem of adjacent feature fusion and redundancy.At the same time,in order to solve the feature similarity problem between different subcategories and improve the classification performance,the interactive guidance module is introduced,which is mainly to interact the feature information extracted by the induction module with[CLS]classification vector.Experiment is carried out on the real customs data set,and the results show that the method can achieve good results,the accuracy is up to 92.98%,and the performance is obviously better than that of each baseline model.
