摘　　要：针对当前神经网络模型未充分考虑标注词语之间的语义关联和预测标签之间的约束关系的问题,提出了一种基于历史信息的目标属性抽取模型。该模型使用注意力机制融合历史的语义信息和预测标签的约束关系,增强特征信息的抽取能力,并利用目标属性和观点项的共现现象进一步提高标注的准确率。实验结果表明,该模型在一定程度上能够提高目标属性抽取网络的性能。Aiming at the current neural network model of semantic relationship between words and the constraint relationship between labels are not fully considered.A target attribute extraction model combining historical information is proposed.The model can enhance the extraction ability of feature information by using the attention mechanism to fuse the historical semantic information and the constraint relationship of the prediction tag,and can further improve the accuracy of the annotation by using the co-occurrence phenomenon of the target and opinion term.Experiments show that the model can improve the performance of the target attribute extraction network to a certain extent.
