Text entailment is a problem in NLP (Natural Language Processing). Here the task is to determine if one piece of text, (aka premise) logically implies another piece of text (aka hypothesis). There are three possible outcomes from a Text Entailment analysis. The hypothesis may be entailed, contradicted or neutral with respect to the premise.
For example, consider the premise: “The elephant is trumpeting”, and the hypothesis: “The elephant is making noise”. In this example, the hypothesis “The elephant is making noise” can be logically inferred from the premise “The elephant is trumpeting”. So, the relationship between the premise and the hypothesis is “entailment”.
