这项研究是第一次使用最近引入的科学网络(WOS)元数据中的开放存取(OA)标签来调查在开放存取期刊目录(DOAJ)列出的期刊上发表的开放存取(OA)文章是否与订阅期刊文章相比具有被引用优势，特别是那些没有自存档版本的文章。对WOS收录的2013至2015年出版的所有文章和评论的文献计量数据进行了分析。除了标准化引文评分(NCS)，我们还使用了两个额外的引文优势衡量标准：一篇文章是否被引用；一篇文章是否在其各自的主题领域内被引用最频繁的百分位数(pptopX%)。对于每个WOS主题领域，计算了访问状态(一篇文章是否发表在办公自动化期刊上)与这三个衡量标准之间的关系强度。我们发现，OA期刊文章在很少的主题领域经历了引用优势，在大多数这些主题领域，引用优势只存在于引用优势的单一衡量标准上，即文章是否被引用。我们的结果导致我们得出结论，访问状态几乎不能解释一篇文章积累的引用数量的变异性。这项研究中使用的方法和计算方法得到了详细的描述，我们相信，我们吸取的经验教训和我们提出的建议，将对未来对使用WOS OA标签感兴趣的研究人员以及一般的引文优势领域有很大帮助。
This study is one of the first that uses the recently introduced open access (OA) labels in the Web of Science (WoS) metadata to investigate whether OA articles published in Directory of Open Access Journals (DOAJ) listed journals experience a citation advantage in comparison to subscription journal articles, specifically those of which no self-archived versions are available. Bibliometric data on all articles and reviews indexed in WoS, and published from 2013 to 2015, were analysed. In addition to normalised citation score (NCS), we used two additional measures of citation advantage: whether an article was cited at all; and whether an article is among the most frequently cited percentile of articles within its respective subject area (pptopX %). For each WoS subject area, the strength of the relationship between access status (whether an article was published in an OA journal) and each of these three measures was calculated. We found that OA journal articles experience a citation advantage in very few subject areas and, in most of these subject areas, the citation advantage was found on only a single measure of citation advantage, namely whether the article was cited at all. Our results lead us to conclude that access status accounts for little of the variability in the number of citations an article accumulates. The methodology and the calculations that were used in this study are described in detail and we believe that the lessons we learnt, and the recommendations we make, will be of much use to future researchers interested in using the WoS OA labels, and to the field of citation advantage in general.
