    Did you search through the Community for a sample process or attempt one on your own?

  • elouanesb90elouanesb90 Member Posts: 3 Contributor I

    yes I do my search but it alowas abut document clustering not word or Term clustering.

    for my attempt I try to do the same thing in document clustering using the word output of Text processing operation as input of the K-means clustering operation but it still not good
