【摘要】：针对科技评估及论证实践中专家知识协作网络的特点,提出专家知识协作"领域-专家-知识"三层加权超网络模型,该模型可以准确刻画专家知识协作的领域社区特性和知识协作机理。在此基础上,构建基于加权超边三角形判定的相似性指标,提出专家知识协作加权超网络的超链路预测方法。仿真结果表明,本文加权超网络模型及其超链路预测方法,能够更准确地预测专家知识协作网络的链路和演化特征,进而可以为科技工作专家体系设计及治理提供科学评价建议。
[Abstract]:In view of the characteristics of expert knowledge cooperation network in scientific and technological evaluation and demonstration practice, a three-layer weighted hypernetwork model of expert knowledge collaboration "domain-expert-knowledge" is proposed. The model can accurately describe the domain community characteristics and knowledge cooperation mechanism of expert knowledge collaboration. On the basis of this, the similarity index based on weighted super-edge triangle decision is constructed, and the hyperlink prediction method based on expert knowledge cooperative weighted hypernetwork is proposed. The simulation results show that the weighted hypernetwork model and its hyperlink prediction method can more accurately predict the link and evolution characteristics of expert knowledge cooperative networks. Furthermore, it can provide scientific evaluation suggestions for the design and management of the expert system of science and technology work.
