You do not want run-on sentences that do not form complete ideas when writing. Your sentences should explain everything without sounding as though some parts of your thought...
Choose TF-IDF vectorization with SVM if the data set is small, i.e. has a small number of classes, a small number of examples and shorter text size, for example, sentences containing fewer phrases. TF-IDF with SVM can be faster than other algorithms in the classification block. Choose TF...
My data is basically sentences, and I extract features from some words of those sentences to do some classification task. Most of my features are nominal: part-of-speech (POS) of the word, word-to-the-left, POS word-to-the-left, word-to-the-right, POS word-to-the-right, synt...
