科研领域中,论文关键词对领域研究特点的表征能力存在差异。针对如何有效地区分关键词对领域研究特色的揭示能力,以高效地提取领域中的特色知识点的问题,提出将科研领域放置于其背景学科中,以全局视角考察关键词在领域内、外的统计特征,并依此提出关键词领域度的概念和计算方法。以“高校图书馆”研究领域为例,根据关键词领域度指标提取50个特色知识点,结果表明,这些特色知识点能很好地揭示“高校图书馆”领域研究的特色。
In the field of scientific research, there are differences in the ability of dissertations to characterize the characteristics of field research. Aiming at how to effectively differentiate the revealing ability of keywords on the research characteristics of the field and to extract the characteristic knowledge points in the field efficiently, this paper puts forward that placing the field of scientific research in its background subject and examining the key words in the field from the global perspective The statistical characteristics of the proposed key areas and the concept of the degree and calculation methods. Taking the field of “University Library” as an example, 50 characteristic knowledge points are extracted according to the key domain index, and the results show that these characteristic knowledge points can well reveal the characteristics of the research in the field of “University Library”.
