TF-IDF.jar is a JavaArchive file to measure TF-IDF of each document
in a document collection (corpus).
The jar can be used to
(a) get all the terms in the corpus
(b) get the document frequency (DF) and inverse document frequency (IDF) of
all the terms in the corpus
(c) get the TF-IDF of each document in the corpus
(d) get each term with their frequency (no. of presence), term frequency (TF) and TF-IDF in every document
