textual-entailment-three-outcomes

Summary

When the system compares two pieces of text, the relationship is not a simple yes-or-no. A statement can be supported by the text, directly contradicted by it, or simply unrelated to it — and treating "unrelated" the same as "contradicted" would lead to false conclusions. This three-way split forces the system to distinguish between "the evidence goes against this" and "the evidence just doesn't address it."
