DenseCNN-ATT:实体关系抽取的密集连接卷积神经网络
《计算机与数字工程》2021年第12期2483-2489,共7页李雅欣 王佳英 单菁 邵明阳 
国家自然科学基金-青年基金项目“海量文本数据下实体智能近似匹配的关键技术研究”(编号:61702346);国家自然科学基金-青年基金项目“基于跨平台资源整合的团队形成深度策略关键技术研究”(编号:61702345);辽宁省教育厅基金项目“面向生物大数据的局部近似匹配技术研究”(编号:lnqn202015)资助。
在远程监督(Distant Supervision,DS)实体关系抽取任务中,采用远程监督的方式虽然可以产生大量的标注数据,但是这种方法产生的数据集充满大量的噪声数据,从而会降低关系抽取的性能。为此,我们针对现有深度学习使用浅层和单一深层神经网...
