The second one is "TF-IDF-All words" which you should write a corpus for the program and it would calculate the TF-IDF of all the words in it. The last one is "TF-IDF-Specific" which you should write a corpuse for the program and after that you need to tell the program which words do you want to calculate it's TF-IDF.
