Dynamic Structures of Science

本研究将尝试使用引文， 期刊来描述科学之间的学科转变。 因子分析将被用来衡量科学的结构 在不同的层次，如学科，子领域， 和专业，以及结构随时间的变化-- 包括跨学科的变化以及 新的科学领域。 一个可靠的方法来跟踪的变化， 学科之间的关系和新领域的出现 这项研究对科学工程有很大的价值 指标和面向政策的受众。的目标 本项目旨在探讨应用 提出的方法及其结果的实用性。创建 描述科学动态结构的方法， 提高我们更准确地反映真实的 按科学领域划分， 固定的日记帐集。

This study will experiment with the use of citations among journals to describe disciplinary shifts among the sciences. Factor analysis will be used to measure the structure of science at various heirarchical levels such as disciplines, subfields and specialties, as well as changes in the structure over time -- including changes in interdisciplinarity as well as the emergence of new areas of science. A reliable methodology for tracking the changes in relationships among disciplines and the emergence of new areas of research would be of great value to Science & Engineering Indicators and to its policy oriented audience. The objective of this project is to explore the practical problems in applying the proposed method and the usefulness of its results. The creation of methods for depicting the dynamic structure of science may improve our capacity to more accurately reflect real levels of national participation by field of science than do the current fixed journal sets.
