基于注意力机制的陆空通话语义感知方法

民航运输过程中陆空通话双方出现信息不一致的问题会威胁飞行安全.为了保障陆空通话的准确性,提出一种基于注意力机制的陆空通话语义感知模型,对陆空通话复诵与问答进行语义感知与判别.该模型结合多种特征向量表示句子并对句子向量进行编码,建立注意力交互矩阵计算指令与答复的软对齐结果,采用前馈神经网络和增强差异性的方法进行语义信息的...

SEMANTIC PERCEPTION OF AVIATION RADIOTELEPHONY COMMUNICATION BASED ON ATTENTION MECHANISM

The inconsistent information between the two sides of radiotelephony communication during civil aviation transportation will threaten flight safety.To ensure the accuracy of radiotelephony communication,we propose a semantic perception model based on the attention mechanism to semantically perceive and discriminate the repetition and question answering of radiotelephony communication.The model combined multiple feature vectors to represent sentences and encode the sentence vectors.It established the attention interaction matrix to calculate the soft alignment results of instructions and responses,and used feedforward neural network and the method of enhancing differentiation to compare and aggregate semantic information,so as to achieve semantic matching and perception.The experimental results show that the test accuracy of the proposed method in radiotelephony communication dataset reaches 94.57%,which is more suitable for semantic analysis in aviation radiotelephony communication than other matching models.
