标签：__ search 爬虫 pubmed sleep 使用 query data
工具
RISmed(library)
中文社区居然没有他的介绍让我匪夷所思,于是乎我做一个简易的介绍吧.
安装
install.packages('RISmed')
使用
library(RISmed)
- 首先我们要定义一个搜索的tag:
search_tags = 'sleep'
然后就可以十分暴力的调用函数了:
- EUtilsSummary
Usage
EUtilsSummary(query,type="esearch",db="pubmed",url=NULL,encoding="unknown",...)
Arguments
query
string query as given in NCBI search box
type
string indicating type of NCBI Eutility
db
string indicating the NCBI database used in query
url
string of url to bypass query construction
encoding
encoding to be assumed for input strings, see readLines
...
additional limits added to query
tips
Windows的同学注意encoding
调用EUtilsSummary
> search_query = EUtilsSummary(search_tags,retmax=100)
> summary(search_query)
Query:
"sleep"[MeSH Terms] OR "sleep"[All Fields]
Result count: 205279
query为search build:
“sleep”[MeSH Terms] OR “sleep”[All Fields]
retmax为文献爬取最大数目
后处理
pubmed_data = data.frame('Title' = ArticleTitle(records),'Abstract'=AbstractText(records))
pubmed_data$Abstract <- as.character(pubmed_data$Abstract)
pubmed_data$Abstract <- gsub(",", " ", pubmed_data$Abstract, fixed = TRUE)
> str(pubmed_data)
'data.frame': 99 obs. of 2 variables:
$ Title : Factor w/ 97 levels "A common hub for sleep and motor control in the substantia nigra.",..: 41 56 49 45 4 35 94 2 83 51 ...
$ Abstract: chr "BACKGROUND: Sleep apnoea is prevalent in dialysis patients.
