Altmetric.com is one of the leading and widely used commercial providers of altmetrics. Altmetrics is a broad term that encapsulates the collection of multiple digital indicators related to scholarly work (NISO, 2016). In this paper, the group of altmetrics provided by Altmetric.com is called Altmetric.com scores. This study assesses whether Altmetric.com scores are currently effective indicators to evaluate the research impact of social sciences and humanities (SSH). This research covers 1,253,028 records from the SSCI and A&HCI for five years (2013–2017), three publication types (articles, reviews, and proceedings papers), and 10 altmetrics provided by Altmetric.com to test the effectiveness of Altmetric.com scores through four proposed dimensions, including transparency, fairness, availability, and validity. Results show that the transparency of Altmetric.com scores is underexposed. And Altmetric.com scores favored English publications authored by North American researchers. Except for Altmetric attention score, Posts, Readers, and Tweeters, the data presence of most Altmetric.com scores was insufficient. As to research impact, Altmetric.com scores can help to reflect different impacts of SSH research. Overall, the results suggest that Altmetric.com scores are not yet sufficiently effective for evaluating the impact of SSH research though they can provide new insights into impact evaluation.

Altmetric.com是Altmetrics的领先和广泛使用的商业提供商之一。Altmetrics是一个广义术语，囊括了与学术工作相关的多个数字指标的集合（NISO，2016）。在本文中，由Altmetric.com提供的一组altmetrics称为Altmetric.com分数。这项研究评估Altmetric.com分数当前是否是评估社会科学与人文科学（SSH）研究影响的有效指标。该研究涵盖SSCI和A＆HCI五年（2013-2017）的1,253,028记录，三种出版物类型（文章，评论和会议论文），以及Altmetric.com提供的10种altmetrics，以通过以下方式测试Altmetric.com分数的有效性建议的四个维度，包括透明度，公平性，可用性和有效性。结果表明，Altmetric.com分数的透明度不足。而且Altmetric.com的得分也受到北美研究人员撰写的英文出版物的青睐。除了Altmetric的注意力得分，帖子，读者和Tweeters以外，大多数Altmetric.com得分的数据不足。至于研究影响，Altmetric.com分数可以帮助反映SSH研究的不同影响。总体而言，结果表明，Altmetric.com评分虽然可以为影响评估提供新的见解，但尚不足以有效评估SSH研究的影响。com分数不足。至于研究影响，Altmetric.com分数可以帮助反映SSH研究的不同影响。总体而言，结果表明，尽管Altmetric.com评分可以为影响评估提供新的见解，但尚不足以有效评估SSH研究的影响。com分数不足。至于研究影响，Altmetric.com分数可以帮助反映SSH研究的不同影响。总体而言，结果表明，Altmetric.com评分虽然可以为影响评估提供新的见解，但尚不足以有效评估SSH研究的影响。
