Data configurations

The TROPICAL dataset has 3 configurations: original, no overlapping, and overlapping.The first one contains the 1592 comments. The overlapping dataset contains the comments that have at least one overlapping triplet. The no overlapping dataset contains the comments that have no overlapping triplet.

Dataset Configuration	Number of comments	Number of triplets	Positive triplets	Negative triplets	Neutral triplets
original	1,592	10,729	9,889	734	106
no_overlapping	467	2,235	2,032	184	19
overlapping	1,125	8,494	7,857	550	87

The following table show the splits of the dataset for all configurations:

Dataset Configuration	Train	Test	Val
original	1,114	239	239
no_overlapping	326	70	71
overlapping	787	169	169

The split values for train, test, validation are 70%, 15%, 15% respectively. The seed used is 42.
