Irrelevant addition: Addition or removal of a word or phrase, that does not affect the meaning of the sentence (as far as the relation of interest is concerned), and can be inferred from the context independently.
Topicalization transformation: A transformation from or to a topicalization construction. Topicalization is a construction in which a clause is moved to the beginning of its enclosing clause.
Apposition transformation: A transformation from or to an apposition construction. In an apposition construction, two noun phrases where one identifies the other are placed one next to each other.
Other syntactic movements: Includes other types of syntactic transformations that are not part of the other categories. This includes cases such as moving an element from a coordinate construction to the subject position as in the last example in Table 8. Another type of transformation is in the following paraphrase: “[X] plays in [Y] position.” and “[X] plays in the position of [Y].” where a compound noun-phrase is replaced with a prepositional phrase.
Different types of paraphrases in ParaRel 🤘. We report examples from each paraphrase type, along with the type of relation, and the number of examples from the specific transformation from a random subset of 100 pairs. Each pair can be classified into more than a single transformation (we report one for brevity), thus the sum of transformation is more than 100.
