Next location recommendation plays an important role in various location-based services, yielding great value for both users and service providers. Existing methods usually model temporal dependencies with explicit time intervals or learn representation from customized point of interest (POI) graphs with rich context information to capture the sequential patterns among POIs. However, this problem is perceptibly complex, because various factors, e.g., users’ preferences, spatial locations, time contexts, activity category semantics, and temporal relations, need to be considered together, while most studies lack sufficient consideration of the collaborative signals. Toward this goal, we propose a novel

MCN4Rec:用于下一个位置推荐的多级协作神经网络
下一个位置推荐在各种基于位置的服务中发挥着重要作用,为用户和服务提供商都带来了巨大的价值。现有方法通常使用明确的时间间隔对时间依赖性进行建模,或者从具有丰富上下文信息的定制兴趣点 (POI) 图中学习表示,以捕获 POI 之间的顺序模式。然而,这个问题显然很复杂,因为需要一起考虑各种因素,例如用户的偏好、空间位置、时间上下文、活动类别语义和时间关系,而大多数研究缺乏对协作信号的充分考虑。为了这个目标,我们提出了一部小说
