| 摘 要： | 科技论文关键词呈现多类型、多关联关系的属性,可以借助具有多层次、多超边的超网络进行表示建模。本研究构建了由研究对象-实验品种-研究用途-技术方法 4层关键词子网和多种关联超边组成的超网络模型,并将该超网络模型用于"农业动物生殖细胞和干细胞调控"领域的科技论文的实证分析。该超网络模型在揭示单层关键词子网同质关联关系的同时,也能挖掘多层子网之间的隐性异质关联关系,从而发现了该领域常用技术方法、实验品种、研究对象和研究用途,同时还发现了该领域的技术空白点和技术应用空白点,这些空白点很可能成为未来的研究热点。

| Abstract: | Keywords in scientific papers present attributes of multiple types and multiple relationships. They can be modeled by a super-network with multiple levels and multiple edges. In this paper, there are 4 layers of research object keywords, experimental variety keywords, research purpose keywords, and technical method keywords. Subsequently, the super-network is applied to scientific papers of"regulation of reproductive cells and stem cells in agricultural animals."The super-network model not only reveals the homogeneous association of a single layer, but also exhibits the hidden heterogeneous associations among multiple layers. As a result, common technical methods, experimental varieties, research objects,and research purposes in the field have been found. At the same time, technical blank spots and application blank spots of technology in the field have also been found, which are likely to be the focus of future research. |
