4914	从用户和物品这 2 个角度，同时考虑用户–物品之间的交互关系和物品–物品之间的功能关系，提出了联合成对排序的推荐模型。	To this end, a co-pairwise ranking model was proposed, which modeled a user's pre-ference for a given item as the combination of user-item interactions and item-item complementarity relationships.
4915	考虑正样本的排名位置和负采样策略直接影响模型收敛速度，构建一种排序感知的学习算法，用于求解所提模型的参数。	Con-sidering that the rank position of positive sample and the negative sampler had a direct impact on the rate of convergence,a rank-aware learning algorithm was devised for optimizing the proposed model. Extensive experiments on fourreal-word datasets are conducted to evaluate of the proposed model.
4916	实验结果表明，与当前主流推荐算法相比，该算法在多个评价指标上具有明显的性能优势。	The experimental results demonstrate that the de-vised algorithm significantly outperforms a series of state-of-the-art recommendation algorithms in terms of multipleevaluation metrics.
4917	针对现有网络架构存在结构僵化、IP 单一承载、难以抑制未知威胁等问题，从网络构造的角度来提升网络的功能、性能、效能、安全等性质，将“结构可定义”贯穿网络的各个层面，提出了一种网络各层功能多模态呈现的网络架构——全维可定义的多模态智慧网络，	For current Internet is confronted with some defects such as rigid structure, single IP bearing, and disability insuppressing unknown threats, the functions, performance, efficiency and security of the Internet were promoted from theperspective of network structure, the “structure definition” was introduced through all levels of the Internet, and a net-work architecture of multi-modal presentation of network functions was provided in all levels: full-dimensional definedpolymorphic smart network (PINet),
