Stem Malay words

stem_malay() will find the root words in a dictionary, in which the malayrootwords data frame can be used, then it will remove “extra suffix”“,”prefix” and lastly “suffix”

To stem word “banyaknya”. It will return a data frame with the word “banyaknya” and the stemmed word “banyak”:

stem_malay(word = "banyaknya", dictionary = malayrootwords)

'Root Word' is now returned instead of 'root_word'
   Col Word Root Word
1 banyaknya    banyak

x <- data.frame(text = c("banyaknya","sangat","terkedu", "pengetahuan"))

stem_malay(word = x, 
          dictionary = malayrootwords, 
          col_feature1 = "text")
  
'Root Word' is now returned instead of 'root_word'
     Col Word Root Word
1   banyaknya    banyak
2      sangat    sangat
3     terkedu      kedu
4 pengetahuan      tahu
