多学科期刊论文学科划分方法研究

Study on Subject Classification of Papers Published in Multidisciplinary Journals

学科划分方法主要有两种,基于期刊分类系统的学科划分以及针对单篇论文进行的学科划分。采用参考文献分析方法与地址认知词分析方法进行多学科期刊单篇论文学科划分,并将划分SCIENCE期刊论文生命科学学科作为实证研究对象。将74个JCR分类界定为生命科学学科,结合期刊全简称对应表进行参考文献分析;研究确定105个地址认知词,在此基础上进行认知词分析。最终将1999-2013年SCIENCE期刊3种文献类型的10 397篇论文划分为生命科学学科,占比为59.12%。

There are two major subject classification methods, including journal-level classification system and subject classification of scientific publications. This paper uses reference analysis and method of cognitive words from corporate addresses to analyze the delimita- tion of scientific subfields and life science of journal SCIENCE as an empirical analysis. 74 JCR classifications are defined as life sciences, references were analyzed combined with the schedule for matching the full name and abbreviated name of the journals referred to; 105 ad- dress cognitive words are extracted, and then on this basis cognitive words were analyzed. As a result, using two methods, the paper cate- gorized 10,397 papers with 3 types of references in SCIENCE journals in 1999 -2013 into life science subject, which accounts for 59.12 percent share of all papers.
