基于社會網(wǎng)絡(luò)分析方法的中國計算機領(lǐng)域科研論文合作規(guī)律探析
[Abstract]:If the authors are regarded as a node in the network, when they publish a paper together, they are connected with each other by an edge, thus forming a cooperative network of papers. In essence, the paper cooperation network is a special social network. M.E.J.Newman, a famous scholar, believes that the cooperative network of papers is a kind of relationship network formed by the scientific research workers to communicate with other researchers and cooperate in the process of carrying out scientific research. From 2000 to 2011, we take 20 kinds of core journals in computer field as data source, construct the paper cooperation network between 2000 and 2011 in computer field, construct the paper cooperation network between 2000 and 2011 in each journal. The thesis cooperation network of computer science and software technology, computer image graphics, computer automation and measurement and control are classified. Cooperative Network of Sensor Theory and Application Journals. The characteristics of the above mentioned networks are analyzed by using the social network analysis method from the angle of the network personality attribute and the whole attribute, and the following conclusions and rules are obtained: (1) the cooperative network in this paper is scale-free network. The core nodes have the characteristics of high value (Large Degree) and high intermediate (Large Betweenness). (2) the cooperative network has multi-core network structure. The network is not a fully connected network. There are some small groups in each network, most of which are national key laboratories or research institutes. (3) the thesis cooperation network has obvious inner core network and peripheral network. Most of the core elements come from the inner core network, and some peripheral network elements play a certain role in the network connection. (4) in the same network, the order of degree and intermediation is not exactly the same; The intermediate rank is not necessarily at the top. Most of these people are interdisciplinary and interdisciplinary researchers. (5) the average path of the cooperative network of computer science and software technology is large, the average clustering coefficient is small, and it has a small world effect, but it is not obvious. (6) there are normal discrete nodes in the network, most of which are new to the cooperative network. Finally, some suggestions and practices for constructing an efficient small group scientific research network are put forward.
