This paper investigates the problem of network embedding, which aims at learning low-dimensional vector representation of nodes in networks. Most existing network embedding methods rely solely on the network structure, i.e., the linkage relationships between nodes, but ignore the rich content information associated with it, which is common in real world networks and beneficial to describing the characteristics of a node. In this paper, we propose content-enhanced network embedding (CENE), which is capable of jointly leveraging the network structure and the content information. Our approach integrates text modeling and structure modeling in a general framework by treating the content information as a special kind of node. Experiments on several real world net- works with application to node classification show that our models outperform all existing network embedding methods, demonstrating the merits of content information and joint learning.

本文研究网络嵌入的问题，提出了内容增强网络嵌入(CENE)的方法，该方法能够联合利用网络结构和内容信息，并通过将内容信息视为特殊节点来将文本建模和结构建模集成在一个通用框架中，试验结果表明，该模型在节点分类应用中胜过其他所有现有的网络嵌入方法，充分证明了内容信息和联合学习的优点。
