摘要： 针对维吾尔语人称代词指代消解研究忽略了待消解项识别而引入了噪声的问题,提出一种基于深度置信网络(Deep Belief Networks,DBN)的维吾尔语人称代词待消解项识别方法。在分析维吾尔语人称代词语法特征和语言规则的基础上,总结出包含10项特征的维吾尔语人称代词待消解项特征集。所提方法首先通过逐层贪婪地训练每一层受限玻尔兹曼机(Restricted Boltzmann Machine,RBM)网络,来保证特征向量映射到不同的特征空间,尽可能多地保留特征信息；并在最后一层设置BP网络,对RBM输出的特征向量进行分类,以有监督的方式训练整个网络并进行微调。实验结果表明,所提方法正确识别维吾尔语人称代词待消解项的准确率达到95.17%,比SVM算法提高了9%,从而验证了其有效性和可行性。
