Question about number of features in a paper In this paper it states that there are 36,787 features, although in Table 3 it states there are clearly 32.
Also how are the words encoded? Is this a one hot encoding they are working with here?

For details, you should probably e-mail the authors, but notice that Table 3 just mentions the classes of the features. For example, Position in sentence has three categories, so after one-hot encoding, this makes three features, Polarity has over three categories, so few more features, Word are probably one-hot encoded unique words, so there could be thousands of them, same with Lemma. Easily this may go into thousands.
