使用来自 pubmedR 的 pmApiRequest 和 pmApi2df 检索到的不完整从属关系

如何解决使用来自 pubmedR 的 pmApiRequest 和 pmApi2df 检索到的不完整从属关系

使用 pubmedR 查找期刊的作者单位时，我发现它们有时不完整。 下面是一个例子：

library(pubmedR)
journal <- "Advances in Clinical Chemistry[JO] AND 2021:2021[DP]"
article_count <- pmQueryTotalCount(query = journal,api_key = NULL)
article_count$total_count
# [1] 21
article_request <- pmApiRequest(query = journal,limit = article_count$total_count,api_key = NULL)
dfa <- pmApi2df(article_request,format = "bibliometrix")

在数据帧“dfa”的“C1”或“AF_UN”列中，我们可以观察到，例如对于第 2 行和第 3 行（PMID 34044912 和 34044911），尽管在相应的 Pubmed 附属机构（分别为冰岛和沙特阿拉伯）中很好地提到了该国家/地区，但并未出现该国家/地区。 https://pubmed.ncbi.nlm.nih.gov/34044912/ https://pubmed.ncbi.nlm.nih.gov/34044911/

如何检索详尽的从属关系？

解决方法

我最终发现从 Pubmed 文章中检索详尽从属关系的最佳方法是来自 ciakovx（感谢他）：

journal <- "Advances in Clinical Chemistry[JO] AND 2021:2021[DP]"
article_count <- pmQueryTotalCount(query = journal,api_key = NULL)
article_count$total_count
# [1] 21

article_request <- pmApiRequest(query = journal,limit = article_count$total_count,api_key = NULL)

dfa <- pluck(article_request,"data") %>% {
  tibble(
    pmid = map_chr(.,pluck,"MedlineCitation","PMID","text"),journal = map(.,"Article","Journal","ISOAbbreviation"),pubdate = map(.,"JournalIssue","PubDate","Year"),affiliation = map(.,"AuthorList","Author","AffiliationInfo","Affiliation")
  )
}
dfa <- as.data.frame(dfa)
