论文摘要
自然，科学和PNA是三个最负盛名的通用科学期刊，自然与科学是总体上最有影响力的期刊之一，基于期刊的影响因素（如果）。在本文中，我们在这些期刊（2005 - 2015年期间出版）中对约50,000篇文章进行自动分类，以探索纪律处分并确定其特定于现场的IF。我们发现，在所有三种期刊中，生物科学，天文学和地球科学的文章都过高，而其他领域的代表性不足，其中一些地区严重严重。例如，在这些期刊中，特定于纪律的IF差异很大，例如，自然界18至46之间的IF差异很大。我们发现，具有最高纪律处分的领域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在所有领域都带来了文章的声望，但是在不同的层面上，最少的是天文学。这三个期刊将自然，科学和PNA的特异性IF与六个最大领域（生物科学，医学，地球科学，物理，天文学和化学）的其他顶级期刊进行比较。
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.
