For the RTE 1-4 corpora, we use the same SR interval scores and the same type of TE values, that means that a pair of sentences could have a SR score on a 5-point-semantic-scale [1-5] that ranges from 1 (completely unrelated) to 5 (very related) and that there are TE values ENTAILMENT, CON-TRADICTION and NEUTRAL.
as the texts in RTE corpora are usually not equal in size/length between the text (T) and the hypothesis (H), and most of the time, one text is (much) longer than the other one, we need to have a specific rule for this case.
