论文摘要
异构信息网络(HIN)已被广泛用于表征各种类型的实体及其复杂关系。最近的尝试要么依赖于明确的路径达到能力来利用基于路径的语义相关性,要么在预测之前学习异质网络表示。这些弱耦合的举止忽略了邻居节点之间的丰富互动,这引入了早期的摘要问题。在本文中,我们提出了Graphhinge(异质相互作用和聚集),该图通过其结构化邻域捕获和聚集了每对节点之间的交互式模式。具体而言,我们首先引入基于邻域的交互(NI)模块,以模拟相同的元数据下的交互式模式,然后将其扩展到基于邻域的交互(CNI)模块以处理不同的Metapaths。接下来,为了解决大规模网络上的复杂性问题,我们通过卷积框架制定交互模块,并通过快速傅立叶变换有效地学习参数。此外,我们设计了一种新型的基于邻里的选择(NS)机制,一种采样策略,以根据其低阶性能过滤高阶邻里信息。对六种不同类型的异质图进行的广泛实验通过与最新的直通率预测和顶级建议任务进行比较,证明了性能的提高。
Heterogeneous information network (HIN) has been widely used to characterize entities of various types and their complex relations. Recent attempts either rely on explicit path reachability to leverage path-based semantic relatedness or graph neighborhood to learn heterogeneous network representations before predictions. These weakly coupled manners overlook the rich interactions among neighbor nodes, which introduces an early summarization issue. In this paper, we propose GraphHINGE (Heterogeneous INteract and aggreGatE), which captures and aggregates the interactive patterns between each pair of nodes through their structured neighborhoods. Specifically, we first introduce Neighborhood-based Interaction (NI) module to model the interactive patterns under the same metapaths, and then extend it to Cross Neighborhood-based Interaction (CNI) module to deal with different metapaths. Next, in order to address the complexity issue on large-scale networks, we formulate the interaction modules via a convolutional framework and learn the parameters efficiently with fast Fourier transform. Furthermore, we design a novel neighborhood-based selection (NS) mechanism, a sampling strategy, to filter high-order neighborhood information based on their low-order performance. The extensive experiments on six different types of heterogeneous graphs demonstrate the performance gains by comparing with state-of-the-arts in both click-through rate prediction and top-N recommendation tasks.
