摘要:

现实世界的网络通常存在多个视图,其中每个视图描述一组公共节点之间的一种类型的交互。例如,在视频共享网络上,虽然如果两个用户节点在一个视图中具有共同喜爱的视频,则它们被链接,但是如果它们共享共同的订户,则它们也可以在另一视图中被链接。与传统的单视图网络不同,多个视图维护不同的语义以相互补充。在本文中,我们提出了MANE,多视图网络嵌入的方法来学习低维表示。与现有的研究类似,MANE取决于多样性和协作-而多样性使视图能够保持其各自的语义,协作使视图能够一起工作。然而,我们还发现了一种以前没有探索过的二阶协作的新形式,并进一步将其统一到我们的框架中,以获得更优的节点表示。此外,由于每个视图通常具有不同的重要性,不同的节点,我们提出了MANE+,一个基于注意力的扩展MANE模型节点的视图重要性。最后,我们在三个公共的、真实世界的多视图网络上进行了全面的实验,结果表明我们的模型始终优于最先进的方法。

英文摘要:

Real-world networks often exist with multiple views, where each view describes one type of interaction among a common set of nodes. For example, on a video-sharing network, while two user nodes are linked if they have common favorite videos in one view, they can also be linked in another view if they share common subscribers. Unlike traditional single-view networks, multiple views maintain different semantics to complement each other. In this paper, we propose MANE, a multi-view network embedding approach to learn low-dimensional representations. Similar to existing studies, MANE hinges on diversity and collaboration - while diversity enables views to maintain their individual semantics, collaboration enables views to work together. However, we also discover a novel form of second-order collaboration that has not been explored previously, and further unify it into our framework to attain superior node representations. Furthermore, as each view often has varying importance w.r.t. different nodes, we propose MANE+, an attention-based extension of MANE to model node-wise view importance. Finally, we conduct comprehensive experiments on three public, real-world multi-view networks, and the results demonstrate that our models consistently outperform state-of-the-art approaches.
