In particular, we can see the exact distribution of the predictions of our algorithm for experiment 8 with a confusion matrix (figure 3).
some measures seem to differ, such as those in experiment 2, which are lower than 0.5, or those in experiment 5, which are lower than 0.6, with both experiments taking into account features related to the context of the question (vectorization in the first case and the presence of words belonging to lexicons in the second one).
