We measured the quality of the paraphrases produced in an experiment , i.e. , -LRB- i -RRB- their grammaticality : at least 99 % correct sentences ; -LRB- ii -RRB- their equivalence in meaning : at least 96 % correct paraphrases either by meaning equivalence or entailment ; and , -LRB- iii -RRB- the amount of internal lexical and syntactical variation in a set of paraphrases : slightly superior to that of hand-produced sets .
 conjunction: equivalence in meaning, grammaticality; used for: meaning equivalence, paraphrases; conjunction: meaning equivalence, entailment; used for: entailment, paraphrases; conjunction: internal lexical and syntactical variation, equivalence in meaning; compare: paraphrases, hand-produced sets
