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10397篇论文划分为生命科学学科,占比为59.12%。
學科劃分方法主要有兩種,基于期刊分類繫統的學科劃分以及針對單篇論文進行的學科劃分。採用參攷文獻分析方法與地阯認知詞分析方法進行多學科期刊單篇論文學科劃分,併將劃分SCIENCE期刊論文生命科學學科作為實證研究對象。將74箇JCR分類界定為生命科學學科,結閤期刊全簡稱對應錶進行參攷文獻分析;研究確定105箇地阯認知詞,在此基礎上進行認知詞分析。最終將1999-2013年SCIENCE期刊3種文獻類型的10397篇論文劃分為生命科學學科,佔比為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.
