Hi , this is my first post, so hello all.
Ok sorted that using multiply but need the term frequency but not total occurances but by document.
So if the word cheap appears in both documents I need to get the amount of occurances in document A and the amount of occurances in document B and NOT the combined total off occurances across both documents.
anyone healp me out with this?? cheers,
(This can be handy in large datasets that are often growing and you have limited memory because you can then batch create TF-IDF by storing the term occurances for each document and calculating the TF-IDF as needed).
