Before revision:  In this paper, we propose a graph embedding method, called ExEm, which using dominating-set theory and deep learning approaches . In the proposed method, the dominating set theory is applied to the collaborative network and dominating nodes of this network are found.
After revision:  In this paper, we propose a graph embedding method, called ExEm, which using dominating-set theory and deep learning approaches to capture node representations. ExEm finds dominating nodes of the collaborative network and dominating nodes of this network are found.
