Read file "Table Manipulation" Right Click -> Interactive View Tokenize text, count word frequencies Extracting simple text vectorsWe can look at the frequency of words and have these word-counts as numbers in a list.Each position in this list (also known as a vector) represents one specific word. We can do this for as many words as we like, can be just a few, or all of them in the corpus (complete body of texts).
