The main problem with this corpus is that the reviews are star base, on a scale of 1 (poor) to 5 (excellent) stars.
in order to be able to compare to the results generated by the developed pipeline we were required to map this expression of sentiment as follows: • 1 and 2 stars: Negative • 3 stars: Neutral • 4 and 5 stars: Positive From the above, we generated a corpus of test and evaluation data.
