内容简介：
如何识别高引用率论文的城市分布状况及其学术价值？主讲人将通过科学计量学的方法，使用谷歌地图和基于Web of Science的科学数据来识别论文引用率高的城市的卓越程度。这种新的映像方法更注重对一个城市优秀论文实际数量的估算，而非期望值。它不仅可以识别论文高产量的城市，还可以发现哪些城市具有高价值的研究成果。通过在物理、化学、心理学领域研究论文的实证分析发现，拥有高引用率论文发表者的城市，并非一定拥有高产量的优秀论文。
The methods presented in this paper allow for a statistical analysis revealing centers of excellence around the world using programs that are freely available. Based on Web of Science data, field-specific excellence can be identified in cities where highly-cited papers were published significantly. Compared to the mapping approaches published hitherto, our approach is more analytically oriented by allowing the assessment of an observed number of excellent papers for a city (in the sample) against the expected number. Using this test, the approach cannot only identify the top performers in output but the "true jewels." These are cities locating authors who publish significantly more top cited papers than can be expected. As the examples in this paper show for physics, chemistry, and psychology, these cities do not necessarily have a high output of excellent papers.
The lecture will largely be based on the paper available at http://arxiv.org/abs/1103.3216 , and to a lesser extent on the paper at http://arxiv.org/abs/1105.2925
