As far as I can remember, it was option 1.
After I choose option 1(before tf-idf weighting scheme), how do I calculate tf-idf weighting for terms which scaled(multiplied) by constant factor s=2.5?
Let assume this condition: term1 in document 3 and document 7 appears in document title, so it will be multiplied by constant factor s=2.5, the matrix is like below:
