I've to create a dataset from some text files, writing them as vectors of features.
Something like this:
doc1: 1,0.45 6,0.001 94,0.1 ...
doc2: 3,0.5 98,0.2 ...
...
each position of the vector represent a word, and the score is given by something like TF-IDF.
Do you know some library/tool/whatever for this? (java is better)
