【摘要】：本文利用网络爬虫技术对万方知识平台的科技论文大数据进行抓取,基于社会网络方法构建了作者合作网络、科研机构合作网络和地区合作网络,对网络的基本属性、关键节点进行了个性化分析。研究发现:中国科技创新论文稳步上升并呈现空间集聚性,"农业"、"大学生"等关键词成为研究热点,产学研合作不断加深,但从区域看,由东向西区域协同创新能力逐渐减弱,核心作者间的信息分享与协同创新较少,处于同一地区、具有相同经营范围或研究方向的机构单位之间更容易展开合作。
[Abstract]:This paper makes use of the technology of web crawler to grasp the scientific and technological paper big data of Wanfang knowledge platform. Based on the method of social network, the author's cooperative network, the cooperative network of scientific research institutions and the regional cooperative network are constructed, and the basic properties of the network are also discussed.The personalization analysis of the key nodes is carried out.It is found that Chinese scientific and technological innovation papers are rising steadily and present spatial agglomeration. Key words such as "agriculture" and "college students" have become the focus of research. The cooperation between industry, education and research has been deepened, but from the regional point of view, the ability of collaborative innovation from east to west has gradually weakened.There is less information sharing and collaborative innovation among core authors, and it is easier to cooperate among institutions with the same business scope or research direction in the same area.
