40620 传统二维重构Toeplitz类算法在进行二维相干信源DOA估计时，利用构造两个相关矩阵或协方差矩阵的部分信息构造Toeplitz矩阵，使得信息利用不完整且需要额外的去噪处理. The traditional two-dimensional reconstruction Toeplitz-like algorithm uses partial information from two correlation matrices or covariance matrices to construct a Toeplitz matrix when performing two-dimensional coherent source DOA estimation, which makes information utilization incomplete and requires additional denoising.

40623 基于事件的社交网络为用户提供线上线下互动模式的社交服务，用户在线上组织事件，线下参与事件. Event based social networks(EBSNs) provides users with online to offline social services. Users can organize events online and participate in them offline.
40624 以往的研究基于因素或基于图实现社交事件推荐，难以充分挖掘社交网络中的语义信息. Particularly, social event recommendation is a hot issue in this field. The existing studies have mainly focused on factors-based or graph-based social event recommendation, which can hardly exploit the semantic information in the social networks thoroughly.
