Detects whether two statements have the identical semantic or not (conveying identical meaning or not)
Two sentences are said to be paraphrase if they yield identical meaning. If the meaning does not come to be identical, they are considered as non-paraphrase.
Paraphrasing conveys something that someone else has said or written in a different manner. With the help of paraphrasing, any piece of writing can be made more informative and interesting.
