匹配 R/nlp/spacyr 中的多个字符串

Question

我有一个数据框

myDataframe <- data.frame(keyword = c(c("meeting", "laptop"),c("attend a meeting", "fan")))
description <- "I have to attend a meeting."

我必须将描述与数据框中的列关键字和 return“参加会议”相匹配。是否有任何解决方案来获得特定的输出

Answer 1

使用 grepl 将 return myDataframe 中的关键字包含在 description

中

myDataframe <- data.frame(keyword = c(c("meeting", "laptop"),c("attend a meeting", "fan")))
description <- "I have to attend a meeting."

found <- as.logical(lapply(myDataframe$keyword ,
                       function(x) grepl(x , description)))

myDataframe[found , ]
#> [1] "meeting"          "attend a meeting"

^{由 reprex package (v2.0.1)}
