利用Plum Metrics评价系统了解论文的关注度分享情况。Plum Metrics也是一个新兴的评价论文价值的指标，Plum Metrics不同于传统的IF等指标，Plum Metrics着重于社会化分享功能。这和利用Altmetric评价系统了解论文的关注度分享情况中提到的Almetric一样。本文简要介绍一下Plum Metrics。
Plum Metrics的评分规则
Plum Metrics是由Andrea Michalek和Mike Buschman两人共同建立的。主要是为了跟踪研究的分享收录和引用情况。Plum Metrics主要基于社会化媒体和分享而评分，一般包括以下几个方面
- 使用情况：包括下载、浏览、传递、收录等
- 保存情况：包括收藏到收藏夹、书签等
- 摘录情况：包括博客、新闻、维基百科、评论等
- 社会分分享：主要是Twitter，G+、喜欢、分享、评级等
- 引用情况：包括PubMed，Scopus等
Plum Metrics包含内容
Plum Metrics不仅包括常见的期刊论文，还包括很多其它的内容。
- 博客文章
- 书籍及其章节
- 个案
- 临床实验
- 会议论文
- 数据集
- 图表
- 许可
- 访谈
- 信件
- 多媒体
