论文摘要
Web of Science Core Collection是最权威的书目数据库之一，在学术界广泛用于跟踪高质量研究。自2017年12月以来，该数据库已开始索引在线第一文章。这种新实践已将两个不同的出版日期（在线和最终出版物日期）介绍到数据库中，以供越来越多的早期访问出版物出版。它可能会使用Web of Science Core Collection提供的出版年度与出版年度相关的工具来搜索或分析文献的许多用户。通过制定自定义检索策略并手动检查，本研究发现，在索引记录的在线和最终出版物日期字段中的搜索页面搜索中的“年度发布”字段。搜索结果页面左侧的每个索引记录仅分配给一个“出版年度”，即使在线出版日期晚于最终出版日期，该记录也将首先从在线出版日期字段中继承。搜索页面中“搜索”页面中的“出版年”字段和时间板“自定义年”字段“自定义年范围”字段与搜索结果页面中的“出版年度”的功能相同。本文末尾还讨论了两个不同出版物日期可用性在计算文献计量指标中的潜在影响。
Web of Science Core Collection, one of the most authoritative bibliographic databases, is widely used in academia to track high-quality research. This database has begun to index online-first articles since December 2017. This new practice has introduced two different publication dates (online and final publication dates) into the database for more and more early access publications. It may confuse many users who want to search or analyze literature by using the publication-year related tools provided by Web of Science Core Collection. By developing custom retrieval strategies and checking manually, this study finds that the "year published" field in search page searches in both online and final publication date fields of indexed records. Each indexed record is allocated to only one "publication year" on the left of the search results page which will inherit first from online publication date field even when the online publication date is later than the final publication date. The "publication year" field in the results analysis page and the timespan "custom year range" field in the search page have the same function as that of the filter "publication year" in search results page. The potential impact of the availability of two different publication dates in calculating bibliometric indicators is also discussed at the end of the article.
