Abstract

本申请提供了一种命名实体识别方法和装置、电子设备及存储介质，属于人工智能技术领域。该方法包括：获取原始句子数据；对原始句子数据进行词嵌入处理，得到原始词嵌入向量；基于预设词表对原始词嵌入向量进行特征融合，得到融合词嵌入向量；对融合词嵌入向量进行零值填充，得到初始词嵌入向量；基于参考句子描述特征对初始词嵌入向量进行特征融合，得到目标词嵌入向量；基于候选标签对目标词嵌入向量进行标签预测，得到预测标签数据；对预测标签数据进行解码处理，得到原始句子数据的目标标签数据；根据目标标签数据，从原始句子数据中提取目标实体对，目标实体对包括用于表征相反语义的一对句子信息。本申请能够提高命名实体识别的准确性。
