摘要： 网络嵌入旨在用低维、实值的向量表示非结构化网络中的节点,使节点嵌入尽可能地保留原始网络中的结构特征与属性特征。然而,当前研究主要集中于嵌入网络结构,对异质信息网络中具有丰富语义的关系属性和节点属性考虑得较少,可能导致节点嵌入语义缺失,从而影响下游应用的预测效果。针对该问题,设计了一种融合多特征的属性异质网络嵌入(Attributed Heterogeneous Network Embedding with Multiple Features,MFAHNE)方法。该方法通过序列采样、结构特征嵌入、属性特征嵌入、特征融合等步骤将网络中的关系属性、节点属性、结构语义等特征融合至最终节点嵌入。实验结果表明,该方法能兼顾结构特征与属性特征,实现两种特征信息的相互补充,优于传统的网络嵌入方法。
