自然、科学和PNAS --学科概况和影响

Nature, Science, and PNAS -- Disciplinary profiles and impact

Staša Milojević

摘要:

《自然》、《科学》和《美国国家科学院院刊》是三种最负盛名的综合科学期刊,根据期刊影响因子(IF),《自然》和《科学》是最具影响力的期刊之一。在本文中,我们对这些期刊(2005-2015年期间出版)中的约50,000篇文章进行了自动分类,分为14个广泛的领域,以探索学科概况并确定其特定领域的IF。我们发现,在所有三种期刊中,来自生物科学,天文学和地球科学的文章都被过度代表,其他领域的文章被代表不足,其中一些严重。这些期刊中的精氨酸特异性IF差异很大,例如,Nature的IF在18和46之间。我们发现,具有最高学科IF的领域并不是贡献最多文章的领域。我们还发现,在这三种期刊上发表文章会给所有领域的文章带来声望,但在不同的层次上,最少的是天文学。将《自然》、《科学》和《美国国家科学院院刊》的特定领域IF与六大领域(生物科学、医学、地球科学、物理学、天文学和化学)的其他顶级期刊进行比较,这三种期刊始终是前七名期刊之一,《自然》在除医学外的所有领域都名列前茅。

英文摘要:

Nature, Science, and PNAS are the three most prestigious general-science journals, and Nature and Science are among the most influential journals overall, based on the journal Impact Factor (IF). In this paper we perform automatic classification of ~50,000 articles in these journals (published in the period 2005-2015) into 14 broad areas, to explore disciplinary profiles and to determine their field-specific IFs. We find that in all three journals the articles from Bioscience, Astronomy, and Geosciences are over-represented, with other areas being under-represented, some of them severely. Discipline-specific IFs in these journals vary greatly, for example, between 18 and 46 for Nature. We find that the areas that have the highest disciplinary IFs are not the ones that contribute the most articles. We also find that publishing articles in these three journals brings prestige for articles in all areas, but at different levels, the least being for Astronomy. Comparing field-specific IFs of Nature, Science and PNAS to other top journals in six largest areas (Bioscience, Medicine, Geosciences, Physics, Astronomy, and Chemistry) these three journals are always among the top seven journals, with Nature being at the very top for all fields except in Medicine.
