A Deep Neural Information Fusion Architecture for Textual Network Embeddings

no code implementations IJCNLP 2019 Zenan Xu, Qinliang Su, Xiaojun Quan, Weijia Zhang

Textual network embeddings aim to learn a low-dimensional representation for every node in the network so that both the structural and textual information from the networks can be well preserved in the representations.
