更改 quanteda KWIC 中关键字的前置词和 post 词的数量
Change the number of pre and post words of a keyword in quanteda KWIC
有没有办法改变 quanteda KWIC 函数中的前置字数和 post 字数？
window 函数在关键字前后给我相同数量的单词，但我需要关键字前后一个单词和五个单词。
最简单的方法是进行两次 kwic() 调用，一次 window 大小为 1，第二次 window 大小为 5。然后，您使用1 号的 pre 作为另一个的 pre。
library("quanteda")
# get a kwic with window size of 1
kwpre <- kwic(data_char_sampletext, "econom*", window = 1)
# store main kwic result in one with window size of 5
kw <- kwic(data_char_sampletext, "econom*", window = 5)
# replace kw pre with the one-word window pre
kw[["pre"]] <- kwpre[["pre"]]
kw
