我们的集体学术知识是如何随着时间的推移而增长的？科学的主要领域是什么？它们是如何相互联系的？哪些领域是主要的知识生产者；哪些领域是消费者？计算科学计量学-将文献计量学/科学计量学方法应用于大规模学术数据集-以及通过科学地图交流结果可能有助于我们回答这些问题。这篇论文代表了一项原型研究的结果，该研究旨在绘制30年来化学研究的结构和演变图。2002年《科学》(SCIE)和《社会科学引文索引》(SSCI)的信息被用来生成包含7,227种期刊和671种期刊群的学科地图。使用JCR类别确定了与研究化学结构和演化相关的簇，并进一步将其聚为14个学科。计算了这14个学科不断变化的科学构成及其通过引文链接进行的知识交流。讨论了化学、生物学、生物化学和生物工程在过去30年中的主导地位、影响和作用的主要变化。论文最后对下一步的工作提出了建议。
How does our collective scholarly knowledge grow over time? What major areas of science exist and how are they interlinked? Which areas are major knowledge producers; which ones are consumers? Computational scientometrics - the application of bibliometric/scientometric methods to large-scale scholarly datasets - and the communication of results via maps of science might help us answer these questions. This paper represents the results of a prototype study that aims to map the structure and evolution of chemistry research over a 30 year time frame. Information from the combined Science (SCIE) and Social Science (SSCI) Citations Indexes from 2002 was used to generate a disciplinary map of 7,227 journals and 671 journal clusters. Clusters relevant to study the structure and evolution of chemistry were identified using JCR categories and were further clustered into 14 disciplines. The changing scientific composition of these 14 disciplines and their knowledge exchange via citation linkages was computed. Major changes on the dominance, influence, and role of Chemistry, Biology, Biochemistry, and Bioengineering over these 30 years are discussed. The paper concludes with suggestions for future work.
