    Okay, I'll ask the question differently for understanding.

     The operators (see picture), for text processing, basically form the process of the "bag-of-word", if I understand it correctly. Because of the definition that a bag-of-words is a representation of text that describes the occurrence of words within a document. It involves two things:

        A vocabulary of known words.

        A measure of the presence of known words.
