物理学中科学生产与消费的特征

Characterizing scientific production and consumption in Physics

Qian Zhang, Nicola Perra, Bruno Goncalves, Fabio Ciulla, Alessandro Vespignani

摘要:

我们分析了整个出版物数据库的美国物理学会产生纵向(50年)引文网络地理定位在单个城市地区的水平。我们定义的知识扩散代理,和科学生产排名算法,以捕捉物理知识的时空动态全球。通过使用知识扩散代理,我们确定了物理学知识生产和消费的关键城市作为时间的函数。科学生产排名算法的结果使我们能够描述物理学学术研究的顶级城市。虽然我们关注的是关于特定领域的单个数据集,但这里提出的方法为跨学科和研究领域的知识动态比较研究开辟了道路

英文摘要:

We analyze the entire publication database of the American Physical Society generating longitudinal (50 years) citation networks geolocalized at the level of single urban areas. We define the knowledge diffusion proxy, and scientific production ranking algorithms to capture the spatio-temporal dynamics of Physics knowledge worldwide. By using the knowledge diffusion proxy we identify the key cities in the production and consumption of knowledge in Physics as a function of time. The results from the scientific production ranking algorithm allow us to characterize the top cities for scholarly research in Physics. Although we focus on a single dataset concerning a specific field, the methodology presented here opens the path to comparative studies of the dynamics of knowledge across disciplines and research areas
