摘要

摘要: 提出了注意力机制独立循环神经网络和胶囊网络并行的维吾尔语事件缺失元素填充模型(Att IndRNN CapsNet).首先, 抽取18项事件和事件元素的内部特征, 作为结合注意力机制的独立循环神经网络模型的输入, 进一步获取高阶特征; 同时, 引入词嵌入技术将事件触发词和候选元素映射为词向量, 通过胶囊网络挖掘事件和事件元素的上下文语义特征; 然后, 将两种特征融合, 作为分类器的输入, 进而完成事件缺失元素的填充. 实验结果表明, 该方法用于维吾尔语事件缺失元素填充准确率为86.94 %, 召回率为84.14 %, 衡量模型整体性能的F1值为85.52 %, 从而证明了该方法在维吾尔语事件缺失元素填充上的有效性.

Abstract: A parallel model (Att IndRNN CapsNet) for missing arguments fllling of Uyghur event is proposed based on attention-mechanical independent recurrent neural network and capsule network. Firstly, 18 features of events and event arguments are extracted, to be the input of the independent recurrent neural network model combined with the attention mechanism, is used to acquire high-order features. At the same time, the word embedding technique is introduced to map the event triggers and candidate arguments into word vectors. The capsule network mines the contextual semantic features of events and event arguments. Then the two kinds of features are fused as the input to the classifler to complete the fllling of the missing arguments of the event. The experimental results show that the accuracy rate of the missing arguments in Uyghur events is 86.94 %, the recall rate is 84.14 %, and the F1 value of the overall performance of the model is 85.52 %, which proves the efiectiveness of the method on the fllling of missing arguments in Uyghur events.
