在科学飞速发展的今天,学科的结构越来越复杂,同时学科间的渗透,又进一步导致了文献的无序与分散;SCI基于引文索引而建立的检索机制十分独特,利用引文索引,可以跨时间跨学科,发现传统的索引方法无法提供的信息,对科研项目的规划和科技前沿课题的调研具有相当重要的作用。
Nowadays, with the rapid development of science, the structure of disciplines is more and more complicated. At the same time, the interdisciplinary infiltration further leads to the disorder and dispersion of documents. The retrieval mechanism established by SCI based on the citation index is very unique. Using the citation index, Time interdisciplinary and found that the traditional indexing method can not provide information, the research project planning and cutting-edge science and technology research has a very important role.
