Results for RQ1:
The plot shows the density of the distribution of method pairs by length (i.e., number of tokens). The vertical red lines represents our cut points (i.e., 50 and 100 tokens).
The plot shows that the highest density of method pairs falls in the two intervals.
The table shows the ten different configurations of the hyperparameters tested. The one highlighted in green is the configuration achieving the best results on the validation set
