Abstract
En 中文
Because many existing algorithms are mainly trained based on the structural features of the networks, the results are more inclined to the structural commonality of the networks. These algorithms ignore the rich external information and node attributes (such as node text content, community and labels, etc. ) that have important implications for network data analysis tasks. Existing network embedding algorithms considering text features usually regard the co -occurrence words in the node's text, or use an induced matrix completion algorithm to factorize the text feature matrix or the network structure feature matrix. Although this kind of algorithm can greatly improve the network embedding performance, they ignore the contribution rate of different cooccurrence words in the node's text. This article proposes a network embedding learning algorithm combining network structure and co -occurrence word features, also incorporating an attention mechanism to model the weight information of the co -occurrence words in the model. This mechanism filters out unimportant words and focuses on important words for learning and training tasks, fully considering the impact of the different co -occurrence words to the model. The proposed network representation algorithm is tested on three open datasets, and the experimental results demonstrate its strong advantages in node classification, visualization analysis, and case analysis tasks.
