You will need to reshape your data. I suggest using Tableau Prep Builder for it.
Basically you will need to split your column that contains the words on the space. Then you will need to pivot all the columns that the split generated to create a column where each word is a row. Finally you need to aggregate the data so that Tableau Prep gives you a new column with the sum of occurrences of each work (number of records).
I hope it helps.
