Two slicing strategies are available:
regular slicing generates quantiles which values are evenly distributed from the minimum to the maximum value.
homogeneous slices produce quantiles gathering roughly the same number of items.
Number of bins
Precise the wanted number of bins, and CorText Manager will devid your dataset according to the chosen slicing strategy.
Alternatively, one can simply type personalized intervals. For instance to produce 5 bins distinguishing between very negative, negative, neutral, positive and very positive sentiment polarity, you would enter: [-10:-4];[-3:-1];;[1:3];[4:10]
